  • the invention further relates to an isolated polypeptide as defined herein having superoxide dismutase activity.
  • amino acid changes in the sequences disclosed above may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino-or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.
  • conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine) , acidic amino acids (glutamic acid and aspartic acid) , polar amino acids (glutamine and asparagine) , hydrophobic amino acids (leucine, isoleucine and valine) , aromatic amino acids (phenylalanine, tryptophan and tyrosine) , and small amino acids (glycine, alanine, serine, threonine and methionine) .
  • Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York.
  • Essential amino acids in the polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085) . In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for SOD activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708.
  • the active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labelling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64.

Abstract

Novel polypeptides of fungal origin with catalase active are active, gastric stable and thermal stable, and effective for use in animal feed additives. The use of fungal catalases in animal feed improve animal growth, animal health and intestinal health of animals.

Description

REDOX ENZYMES IN ANIMAL FEED COMPOSITIONS
This application contains a Sequence Listing in computer readable form, which is incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to the use of polypeptides having catalase activity for
● improving one or more performance parameters, wherein the one or more performance parameters is selected from the group consisting of the European Production Efficiency Factor (EPEF) , Feed Conversion Ratio (FCR) , Growth Rate (GR) , Body Weight Gain (WG) , Mortality Rate (MR) and Flock Uniformity (FU) ,
● improving or enhancing immune response and/or reducing inflammation and/or for the modulation of the gut flora in an animal, and
● reducing or eliminating the use of antibiotics administered to animal feed.
The present invention also relates to new polypeptides having catalase activity.
BACKGROUND OF THE INVENTION
Catalases are able to degrade hydrogen peroxide into water and oxygen. A catalase is classified as an EC 1.11.1.6 catalase or as an EP 1.11.1.21 catalase peroxidase.
Known catalases of mammalian origin have been found to have low relative gastric stability thereby impeding their use in feed.
Surprisingly, the inventors of the present invention have found that catalasess of fungal origin, have both high activity and gastric stability, and can therefore be used in an animal feed or animal feed additive. It has further been found that thee use of catalase in animal feed can to improve one or more performance parameters, enhance immune response and reduce inflammation in an animal and thus lead to many advantages such as improving animal health and/or animal performance, and/or reducing feeding cost.
SUMMARY OF THE INVENTION
The present invention relates to animal feed additive comprising a polypeptide of fungal origin having catalase activity and optionally a polypeptide having superoxide dismutase activity. The present invention relates to an animal feed or animal feed additive comprising one or more polypeptides having catalase activity. The present invention relates to an animal feed or animal feed additive comprising one or more polypeptides having catalase activity. Alternatively  defined, the present invention relates to an animal feed additive comprising at least one and no more than two enzyme classes, wherein the at least one enzyme class is a catalase and the optional second enzyme class is a superoxide dismutase of fungal or microbial origin. An aspect of the invention is directed to an animal feed additive comprising an enzyme component, wherein the enzyme component comprises all of the enzymes of the additive and consists of a catalase of fungal orgin and optionally of a superoxide dismutase. Typically, the superoxide dismutase is of fungal or microbial origin.
A further aspect of the invention is directed to an animal feed additive comprising at least one and no more than two enzyme classes, wherein the at least one enzyme class is a catalase of fungal origin and the optional second enzyme class is a superoxide dismutase of fungal origin.

Concentrates: The term “concentrates” means feed with high protein and energy concentrations, such as fish meal, molasses, oligosaccharides, sorghum, seeds and grains (either whole or prepared by crushing, milling, etc. from e.g. corn, oats, rye, barley, wheat) , oilseed press cake (e.g. from cottonseed, safflower, sunflower, soybean (such as soybean meal) , rapeseed/canola, peanut or groundnut) , palm kernel cake, yeast derived material and distillers grains (such as wet distillers grains (WDS) and dried distillers grains with solubles (DDGS) ) .
Feed efficiency: The term “feed efficiency” means the amount of weight gain per unit of feed when the animal is fed ad-libitum or a specified amount of food during a period of time. By "increased feed efficiency" it is meant that the use of a feed additive composition according the present invention in feed results in an increased weight gain per unit of feed intake compared with an animal fed without said feed additive composition being present.
Feed Conversion Ratio (FCR) : FCR is a measure of an animal's efficiency in converting feed mass into increases of the desired output. Animals raised for meat –such as swine, poultry and fish –the output is the mass gained by the animal. Specifically, FCR is calculated as feed intake divided by weight gain, all over a specified period. Improvement in FCR means reduction of the FCR value. An FCR improvement of 2%means that the FCR was reduced by 2%.
Feed Premix: The incorporation of the composition of feed additives as exemplified herein above to animal feeds, for example poultry feeds, is in practice carried out using a concentrate or a premix. A premix designates a preferably uniform mixture of one or more microingredients with diluent and/or carrier. Premixes are used to facilitate uniform dispersion of micro-ingredients in a larger mix. A premix according to the invention can be added to feed ingredients or to the drinking water as solids (for example as water soluble powder) or liquids.
European Production Efficiency Factor (EPEF) : The European Production Efficiency Factor is a way of comparing the performance of animals. This single-figure facilitates comparison of performance within and among farms and can be used to assess environmental, climatic and animal management variables. The EPEF is calculated as [ (liveability (%) x Liveweight (kg) ) / (Age at depletion (days) x FCR) ] x 100, wherein livability is the percentage of animals alive at slaughter, Liveweight is the average weight of the animals at slaughter, age of depletion is the age of the animals at slaughter and FCR is the feed conversion ratio at slaughter.
Forage: The term “forage” as defined herein also includes roughage. Forage is fresh plant material such as hay and silage from forage plants, grass and other forage plants, seaweed, sprouted grains and legumes, or any combination thereof. Examples of forage plants are Alfalfa (lucerne) , birdsfoot trefoil, brassica (e.g. kale, rapeseed (canola) , rutabaga (swede) , turnip) , clover (e.g. alsike clover, red clover, subterranean clover, white clover) , grass (e.g.  Bermuda grass, brome, false oat grass, fescue, heath grass, meadow grasses, orchard grass, ryegrass, Timothy-grass) , corn (maize) , millet, barley, oats, rye, sorghum, soybeans and wheat and vegetables such as beets. Forage further includes crop residues from grain production (such as corn stover; straw from wheat, barley, oat, rye and other grains) ; residues from vegetables like beet tops; residues from oilseed production like stems and leaves form soy beans, rapeseed and other legumes; and fractions from the refining of grains for animal or human consumption or from fuel production or other industries.

As the SODs defined above are novel enzymes, the invention further relates to an isolated polypeptide as defined herein having superoxide dismutase activity.
The amino acid changes in the sequences disclosed above may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-30 amino acids; small amino-or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by  changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.
Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine) , acidic amino acids (glutamic acid and aspartic acid) , polar amino acids (glutamine and asparagine) , hydrophobic amino acids (leucine, isoleucine and valine) , aromatic amino acids (phenylalanine, tryptophan and tyrosine) , and small amino acids (glycine, alanine, serine, threonine and methionine) . Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.
Essential amino acids in the polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085) . In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for SOD activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labelling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide.

Metals of superoxide dismutases
In an embodiment of the invention the polypeptide having superoxide dismutase activity is of fungal origin and is selected selected from the group consisting of a Cu-SOD, a Zn-SOD, a Cu/Zn-SOD, a Mn-SOD, and an Fe-SOD, more typically a Cu-SOD, a Zn-SOD, a Cu/Zn-SOD, a Mn-SOD, and an Fe-SOD, even more typically a Cu-SOD, a Zn-SOD, a Cu/Zn-SOD, or a Mn-SOD.
In a suitable embodiment of the invention the polypeptide having superoxide dismutase activity is of fungal origin and is selected from the group consisting of a Cu-SOD and a Cu/Zn-SOD.
The copper ion is involved in the catalysis of Cu-SODs whereas the zinc ion plays a structural role. The redox active copper catalyzes the disproportionation of superoxide anion to oxygen and hydrogen peroxide, whereas the zinc helps stabilize the protein and promotes pH independence of the reaction.

In one embodiment of the invention, the superoxide dismutase of fungal origin has an activity of at least 1000 U/mg at pH 7.8, such as at least 1500 U/mg, or at least 2000 U/mg, or at least  3000 U/mg, or at least 4000 U/mg, or at least 5000 U/mg, suitably as measured by the method described in Example 9.
SEQ ID NO 1, SEQ ID NO 9, SEQ ID NO 15, SEQ ID NO 21, SEQ ID NO 24, SEQ ID NO 28, SEQ ID NO 29, SEQ ID NO 30, SEQ ID NO 31, SEQ ID NO 32, SEQ ID NO 33, SEQ ID NO 34, SEQ ID NO 35, SEQ ID NO 39, SEQ ID NO 41, SEQ ID NO 42, SEQ ID NO 44, SEQ ID NO 45, and SEQ ID NO 48 all have an activity near, at or over 3000 U/mg EP when measured according to the method described in Example 9 or at pH 7.8.
Gastric Stability of superoxide dismutases
In a preferred embodiment, the SOD, given it is intended for use as an animal feed additive, is gastric stable, when measured according to the method described in Example 10. As can be seen from the table in Example 10, the commercially available superoxide dismutase from bovine erythrocytes and expressed in E. coli of sequence A:

Two commercial SODs were tested as references: SOD-Mn, from E. coli Sigma S5639 with a activity of 10240 U/mg EP and only 26%activity left after gastric press for 30 min; and SOD-Cu/Zn from Bovine expressed in E. coli Sigma S9697 with activity of 6108 U/mg EP and only 35%activity left after gastric press for 30min.
The fungal SODs of the invention were overwhelmingly and surprisingly found to have a very high gastric stability (see Gastric Stability Table) . Moreover, some SODs even have higher activity under gastric stability studies than at the reference pH, indicating that they are more active at low pH. This makes fungal SODs very well suited for use in vivo by means of administration through animal feed.

Thermal Stability of superoxide dismutase
The commercially available E. coli and bovine SODs are tested at 25℃ and stored at -20℃. An animal feed additive for use in animal feed is prepared by a pelleting process, transported by land or sea, stored, and consumed by animals with body temperatures over 30℃ and at gastric pH conditions. Transport and pelleting may lead to temperatures reaching 45℃. Accordingly, thermal stability in each of these conditions is highly pertinent for use of a super oxide dismutase in an animal feed additive.
Test were performed on the super oxide dismutases of the invention to measure the temperature at different acidity/alkalinity to determine the temperature at which the polypeptide unfolds and denatures. As can be seen, from the “Thermal Stability Table with pH” , unfolding of the fungal superoxide dismutase takes place at over 45℃, as measured by the Tm, for all fungal superoxide dismutases at neutral pH (pH7) . A further embodiment is directed to an animal feed additive comprising a fungal superoxide dismutase thermally stable at pH 7, when measured according to the method described in Example 11, such that protein unfolding (Tm) is 45℃ or more.
At gastric pH (pH 3) , fungal superoxide dismutases have been found to be stable at normal body temperatures for farm animals. A further embodiment of the invention is directed to an animal feed additive comprising a fungal superoxide dismutase thermally stable at pH 3, when measured according to the method described in Example 11, such that protein unfolding (Tm) is 35℃ or more, such as 40℃ or more, such as 45℃ or more.
In a preferred embodiment, the animal feed additive of the invention is thermal stable, when measured according to the method described in Example 11. The commercially available superoxide dismutase from bovine erythrocytes and expressed in E. coli of sequence A:

For a solid formulation, the formulation may be for example as a granule, spray dried powder or agglomerate (e.g. as disclosed in WO2000/70034) . The formulating agent may comprise a salt (organic or inorganic zinc, sodium, potassium or calcium salts such as e.g. such as calcium acetate, calcium benzoate, calcium carbonate, calcium chloride, calcium citrate, calcium sorbate, calcium sulfate, potassium acetate, potassium benzoate, potassium carbonate, potassium chloride, potassium citrate, potassium sorbate, potassium sulfate, sodium acetate, sodium benzoate, sodium carbonate, sodium chloride, sodium citrate, sodium sulfate, zinc acetate, zinc benzoate, zinc carbonate, zinc chloride, zinc citrate, zinc sorbate, zinc sulfate) , starch or a sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol) .
In one embodiment, the composition is a solid composition, such as a spray dried composition, comprising the polypeptide having SOD activity of the invention and one or more formulating agents selected from the list consisting of sodium chloride, sodium benzoate, potassium sorbate, sodium sulfate, potassium sulfate, magnesium sulfate, sodium thiosulfate, calcium carbonate, sodium citrate, dextrin, glucose, sucrose, sorbitol, lactose, starch and cellulose. In a preferred embodiment, the formulating agent is selected from one or more of the following compounds: sodium sulfate, dextrin, cellulose, sodium thiosulfate, magnesium sulfate and calcium carbonate.
The present invention also relates to enzyme granules/particles comprising the polypeptide having catalase activity of the invention optionally combined with one or more additional enzymes. The granule is composed of a core, and optionally one or more coatings (outer layers) surrounding the core.
Typically, the granule/particle size, measured as equivalent spherical diameter (volume based average particle size) , of the granule is 20-2000 μm, particularly 50-1500 μm, 100-1500 μm or 250-1200 μm.
The core can be prepared by granulating a blend of the ingredients, e.g., by a method comprising granulation techniques such as crystallization, precipitation, pan-coating, fluid bed  coating, fluid bed agglomeration, rotary atomization, extrusion, prilling, spheronization, size reduction methods, drum granulation, and/or high shear granulation.
Methods for preparing the core can be found in Handbook of Powder Technology; Particle size enlargement by C.E. Capes; Volume 1; 1980; Elsevier. Preparation methods include known feed and granule formulation technologies, e.g.:
a) spray dried products, wherein a liquid enzyme-containing solution is atomized in a spray drying tower to form small droplets which during their way down the drying tower dry to form an enzyme-containing particulate material;
b) layered products, wherein the enzyme is coated as a layer around a pre-formed inert core particle, wherein an enzyme-containing solution is atomized, typically in a fluid bed apparatus wherein the pre-formed core particles are fluidized, and the enzyme-containing solution adheres to the core particles and dries up to leave a layer of dry enzyme on the surface of the core particle. Particles of a desired size can be obtained this way if a useful core particle of the desired size can be found. This type of product is described in, e.g., WO 97/23606;
c) absorbed core particles, wherein rather than coating the enzyme as a layer around the core, the enzyme is absorbed onto and/or into the surface of the core. Such a process is described in WO 97/39116.
d) extrusion or pelletized products, wherein an enzyme-containing paste is pressed to pellets or under pressure is extruded through a small opening and cut into particles which are subsequently dried. Such particles usually have a considerable size because of the material in which the extrusion opening is made (usually a plate with bore holes) sets a limit on the allowable pressure drop over the extrusion opening. Also, very high extrusion pressures when using a small opening increase heat generation in the enzyme paste, which is harmful to the enzyme;
e) prilled products, wherein an enzyme-containing powder is suspended in molten wax and the suspension is sprayed, e.g., through a rotating disk atomiser, into a cooling chamber where the droplets quickly solidify (Michael S. Showell (editor) ; Powdered detergents; Surfactant Science Series; 1998; vol. 71; page 140-142; Marcel Dekker) . The product obtained is one wherein the enzyme is uniformly distributed throughout an inert material instead of being concentrated on its surface. Also US 4,016,040 and US 4,713,245 are documents relating to this technique;
f) mixer granulation products, wherein a liquid is added to a dry powder composition of, e.g., conventional granulating components, the enzyme being introduced either via the liquid or the powder or both. The liquid and the powder are mixed and as the moisture of the liquid is absorbed in the dry powder, the components of the dry powder will start to adhere and agglomerate and particles will build up, forming granulates comprising the enzyme. Such a process is described in US 4,106,991 and related documents EP 170360, EP 304332, EP 304331, WO 90/09440 and WO 90/09428. In a particular product of this process wherein  various high-shear mixers can be used as granulators, granulates consisting of enzyme as enzyme, fillers and binders etc. are mixed with cellulose fibres to reinforce the particles to give the so-called T-granulate. Reinforced particles, being more robust, release less enzymatic dust.
g) size reduction, wherein the cores are produced by milling or crushing of larger particles, pellets, tablets, briquettes etc. containing the enzyme. The wanted core particle fraction is obtained by sieving the milled or crushed product. Over and undersized particles can be recycled. Size reduction is described in (Martin Rhodes (editor) ; Principles of Powder Technology; 1990; Chapter 10; John Wiley &Sons) ;
h) fluid bed granulation, which involves suspending particulates in an air stream and spraying a liquid onto the fluidized particles via nozzles. Particles hit by spray droplets get wetted and become tacky. The tacky particles collide with other particles and adhere to them and form a granule;
i) the cores may be subjected to drying, such as in a fluid bed drier. Other known methods for drying granules in the feed or detergent industry can be used by the skilled person. The drying preferably takes place at a product temperature of from 25 to 90℃. For some enzymes it is important the cores comprising the enzyme contain a low amount of water before coating. If water sensitive enzymes are coated before excessive water is removed, it will be trapped within the core and it may affect the activity of the enzyme negatively. After drying, the cores preferably contain 0.1-10 %w/w water.
The core may include additional materials such as fillers, fibre materials (cellulose or synthetic fibres) , stabilizing agents, solubilizing agents, suspension agents, viscosity regulating agents, light spheres, plasticizers, salts, lubricants and fragrances.
The core may include a binder, such as synthetic polymer, wax, fat, or carbohydrate.
The core may include a salt of a multivalent cation, a reducing agent, an antioxidant, a peroxide decomposing catalyst and/or an acidic buffer component, typically as a homogenous blend.
In one embodiment, the core comprises a material selected from the group consisting of salts (such as calcium acetate, calcium benzoate, calcium carbonate, calcium chloride, calcium citrate, calcium sorbate, calcium sulfate, potassium acetate, potassium benzoate, potassium carbonate, potassium chloride, potassium citrate, potassium sorbate, potassium sulfate, sodium acetate, sodium benzoate, sodium carbonate, sodium chloride, sodium citrate, sodium sulfate, zinc acetate, zinc benzoate, zinc carbonate, zinc chloride, zinc citrate, zinc sorbate, zinc sulfate) , starch or a sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol) , sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol) , small organic molecules, starch, flour, cellulose and minerals and clay minerals (also known as hydrous aluminium phyllosilicates) . In one embodiment, the core comprises a clay mineral such as kaolinite or kaolin.
The core may include an inert particle with the enzyme absorbed into it, or applied onto the surface, e.g., by fluid bed coating.
The core may have a diameter of 20-2000 μm, particularly 50-1500 μm, 100-1500 μm or 250-1200 μm.
The core may be surrounded by at least one coating, e.g., to improve the storage stability, to reduce dust formation during handling, or for coloring the granule. The optional coating (s) may include a salt and/or wax and/or flour coating, or other suitable coating materials.
The coating may be applied in an amount of at least 0.1%by weight of the core, e.g., at least 0.5%, 1%or 5%. The amount may be at most 100%, 70%, 50%, 40%or 30%.
The coating is preferably at least 0.1 μm thick, particularly at least 0.5 μm, at least 1 μm or at least 5 μm. In some embodiments the thickness of the coating is below 100 μm, such as below 60 μm, or below 40 μm.
The coating should encapsulate the core unit by forming a substantially continuous layer. A substantially continuous layer is to be understood as a coating having few or no holes, so that the core unit is encapsulated or enclosed with few or no uncoated areas. The layer or coating should in particular be homogeneous in thickness.
The coating can further contain other materials as known in the art, e.g., fillers, antisticking agents, pigments, dyes, plasticizers and/or binders, such as titanium dioxide, kaolin, calcium carbonate or talc.
The granule may comprise a core comprising the polypeptide having SOD activity of the invention, one or more salt coatings and one or more wax coatings. Examples of enzyme granules with multiple coatings are shown in WO1993/07263, WO1997/23606 and WO2016/149636.
A salt coating may comprise at least 60%by weight of a salt, e.g., at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%or at least 99%by weight.

The term “mortality” as used herein refers to the ratio of life animals at the end of the growth phase versus the number of animals originally included into the pond. It may be determined on the basis of a fish challenge trial comprising two groups of fish challenged by a particular fish pathogen with the aim to provoke a mortality of 40 to 80 %of the animals in the untreated group. However, in the challenge group fed with a suitable concentration per Kg of feed of a mixture of at least two compounds according to the invention, the mortality is reduced compared to the untreated group by at least 5 %, preferably at least, 10 %, 15 %, 20 %, 25 %, 30 %, 35 %, 40 %, 45 %, or at least 50 %.

In some embodiments,, the invention relates to an animal feed and a method of improving or enhancing immune response and/or reducing inflammation and/or for the modulation of the gut flora in an animal comprising administering to the animal an animal feed or animal feed additive comprising one or more polypeptides having superoxide dismutase activity.
These features are supported by example 1 as the first two features are very much linked to oxidative stress. Different in-vitro models tested by the applicant also show that SODs optionally in combinations with a catalase are very effective to decrease oxidative stress /burst.
Dysregulating effects of heat stress and oxidative stress also help in maintaining gut integrity and function. Therefore, the invention also supports a positive modulation of the gut flora, in particular of the microbial gut flora.
The term "gut" as used herein designates the gastrointestinal or digestive tract (also referred to as the alimentary canal) and it refers to the system of organs within multi-cellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.
The term gut "microflora" as used herein refers to the natural microbial cultures residing in the gut and maintaining health by aiding in proper digestion. The term "modulate" as used herein in connection with the gut microflora generally means to change, manipulate, alter, or adjust the function or status thereof in a healthy and normally functioning animal, i.e. a non-therapeutic use.
The term “supporting immune system function” as used herein refers to the immune stimulation effect obtained by the compounds according to the invention.
In the fifth and sixth embodiment, the invention relates to a method of reducing or eliminating the use of antibiotics administered to animal feed or to a method of reducing cellular markers of reactive oxygen species or free radicals in animal body comprising administering to the animal an animal feed or animal feed additive comprising one or more polypeptides having catalase activity. These embodiments are supported by examples 1 to 4.
In the seventh embodiment, the invention relates to an animal feed additive or animal feed premix comprising one or more polypeptides having superoxide dismutase (SOD) , wherein the feed additive or premix further comprises

The energy source of the animal feed is selected from the group consisting of maize, corn, sorghum, barley, wheat, oats, rice, triticale, rye, beet, sugar beet, spinach, potato, cassava, quinoa, cabbage, switchgrass, millet, pearl millet, foxtail millet or in a processed form such as milled corn, milled maize, potato starch, cassava starch, milled sorghum, milled switchgrass, milled millet, milled foxtail millet, milled pearl millet, or any combination thereof.
In a preferred example, the animal feed further comprises one or more components selected from the list consisting of one or more additional enzymes; one or more microbes; one or more vitamins; one or more minerals; one or more amino acids; and one or more other feed ingredients, as described herein.
In a further embodiment, the invention relates to an animal feed additive or animal feed premix comprising one or more polypeptides having catalase activity, wherein the feed additive or premix further comprises
c. one or more polypeptides having superoxide dismutase activity and/or

For a solid formulation, the formulation may be for example as a granule, spray dried powder or agglomerate (e.g. as disclosed in WO2000/70034) . The formulating agent may comprise a salt (organic or inorganic zinc, sodium, potassium or calcium salts such as e.g. such as calcium acetate, calcium benzoate, calcium carbonate, calcium chloride, calcium citrate, calcium sorbate, calcium sulfate, potassium acetate, potassium benzoate, potassium carbonate, potassium chloride, potassium citrate, potassium sorbate, potassium sulfate, sodium acetate, sodium benzoate, sodium carbonate, sodium chloride, sodium citrate, sodium sulfate, zinc acetate, zinc benzoate, zinc carbonate, zinc chloride, zinc citrate, zinc sorbate, zinc sulfate) , starch or a sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol) .
In one embodiment, the composition is a solid composition, such as a spray dried composition, comprising the polypeptide having catalase activity of the invention and one or more formulating agents selected from the list consisting of sodium chloride, sodium benzoate, potassium sorbate, sodium sulfate, potassium sulfate, magnesium sulfate, sodium thiosulfate, calcium carbonate, sodium citrate, dextrin, glucose, sucrose, sorbitol, lactose, starch and cellulose. In a preferred embodiment, the formulating agent is selected from one or more of the following compounds: sodium sulfate, dextrin, cellulose, sodium thiosulfate, magnesium sulfate and calcium carbonate.
The present invention also relates to enzyme granules/particles comprising the polypeptide having catalase activity of the invention optionally combined with one or more additional enzymes. The granule is composed of a core, and optionally one or more coatings (outer layers) surrounding the core.
Typically, the granule/particle size, measured as equivalent spherical diameter (volume based average particle size) , of the granule is 20-2000 μm, particularly 50-1500 μm, 100-1500 μm or 250-1200 μm.
The core can be prepared by granulating a blend of the ingredients, e.g., by a method comprising granulation techniques such as crystallization, precipitation, pan-coating, fluid bed coating, fluid bed agglomeration, rotary atomization, extrusion, prilling, spheronization, size reduction methods, drum granulation, and/or high shear granulation.
Methods for preparing the core can be found in Handbook of Powder Technology; Particle size enlargement by C.E. Capes; Volume 1; 1980; Elsevier. Preparation methods include known feed and granule formulation technologies, e.g.:
a) spray dried products, wherein a liquid enzyme-containing solution is atomized in a spray drying tower to form small droplets which during their way down the drying tower dry to form an enzyme-containing particulate material;
b) layered products, wherein the enzyme is coated as a layer around a pre-formed inert core particle, wherein an enzyme-containing solution is atomized, typically in a fluid bed apparatus wherein the pre-formed core particles are fluidized, and the enzyme-containing solution adheres to the core particles and dries up to leave a layer of dry enzyme on the surface of the core particle. Particles of a desired size can be obtained this way if a useful core particle of the desired size can be found. This type of product is described in, e.g., WO 97/23606;
c) absorbed core particles, wherein rather than coating the enzyme as a layer around the core, the enzyme is absorbed onto and/or into the surface of the core. Such a process is described in WO 97/39116.
d) extrusion or pelletized products, wherein an enzyme-containing paste is pressed to pellets or under pressure is extruded through a small opening and cut into particles which are subsequently dried. Such particles usually have a considerable size because of the material in which the extrusion opening is made (usually a plate with bore holes) sets a limit on the allowable pressure drop over the extrusion opening. Also, very high extrusion pressures when using a small opening increase heat generation in the enzyme paste, which is harmful to the enzyme;
e) prilled products, wherein an enzyme-containing powder is suspended in molten wax and the suspension is sprayed, e.g., through a rotating disk atomiser, into a cooling chamber where the droplets quickly solidify (Michael S. Showell (editor) ; Powdered detergents; Surfactant Science Series; 1998; vol. 71; page 140-142; Marcel Dekker) . The product obtained is one wherein the enzyme is uniformly distributed throughout an inert material instead of being concentrated on its surface. Also US 4,016,040 and US 4,713,245 are documents relating to this technique;
f) mixer granulation products, wherein a liquid is added to a dry powder composition of, e.g., conventional granulating components, the enzyme being introduced either via the liquid or the powder or both. The liquid and the powder are mixed and as the moisture of the liquid is absorbed in the dry powder, the components of the dry powder will start to adhere and agglomerate and particles will build up, forming granulates comprising the enzyme. Such a process is described in US 4,106,991 and related documents EP 170360, EP 304332, EP 304331, WO 90/09440 and WO 90/09428. In a particular product of this process wherein various high-shear mixers can be used as granulators, granulates consisting of enzyme as enzyme, fillers and binders etc. are mixed with cellulose fibres to reinforce the particles to give the so-called T-granulate. Reinforced particles, being more robust, release less enzymatic dust.
g) size reduction, wherein the cores are produced by milling or crushing of larger particles, pellets, tablets, briquettes etc. containing the enzyme. The wanted core particle fraction is obtained by sieving the milled or crushed product. Over and undersized particles can be recycled. Size reduction is described in (Martin Rhodes (editor) ; Principles of Powder Technology; 1990; Chapter 10; John Wiley &Sons) ;
h) fluid bed granulation, which involves suspending particulates in an air stream and spraying a liquid onto the fluidized particles via nozzles. Particles hit by spray droplets get wetted and become tacky. The tacky particles collide with other particles and adhere to them and form a granule;
i) the cores may be subjected to drying, such as in a fluid bed drier. Other known methods for drying granules in the feed or detergent industry can be used by the skilled person. The drying preferably takes place at a product temperature of from 25 to 90℃. For some enzymes it is important the cores comprising the enzyme contain a low amount of water before coating. If water sensitive enzymes are coated before excessive water is removed, it will be trapped within the core and it may affect the activity of the enzyme negatively. After drying, the cores preferably contain 0.1-10 %w/w water.
The core may include additional materials such as fillers, fibre materials (cellulose or synthetic fibres) , stabilizing agents, solubilizing agents, suspension agents, viscosity regulating agents, light spheres, plasticizers, salts, lubricants and fragrances.
The core may include a binder, such as synthetic polymer, wax, fat, or carbohydrate.
The core may include a salt of a multivalent cation, a reducing agent, an antioxidant, a peroxide decomposing catalyst and/or an acidic buffer component, typically as a homogenous blend.
In one embodiment, the core comprises a material selected from the group consisting of salts (such as calcium acetate, calcium benzoate, calcium carbonate, calcium chloride, calcium citrate, calcium sorbate, calcium sulfate, potassium acetate, potassium benzoate, potassium carbonate, potassium chloride, potassium citrate, potassium sorbate, potassium sulfate, sodium acetate, sodium benzoate, sodium carbonate, sodium chloride, sodium citrate, sodium sulfate, zinc acetate, zinc benzoate, zinc carbonate, zinc chloride, zinc citrate, zinc sorbate, zinc sulfate) , starch or a sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol) , sugar or sugar derivative (such as e.g. sucrose, dextrin, glucose, lactose, sorbitol) , small organic molecules, starch, flour, cellulose and minerals and clay minerals (also known as hydrous aluminium phyllosilicates) . In one embodiment, the core comprises a clay mineral such as kaolinite or kaolin.
The core may include an inert particle with the enzyme absorbed into it, or applied onto the surface, e.g., by fluid bed coating.
The core may have a diameter of 20-2000 μm, particularly 50-1500 μm, 100-1500 μm or 250-1200 μm.
The core may be surrounded by at least one coating, e.g., to improve the storage stability, to reduce dust formation during handling, or for coloring the granule. The optional coating (s) may include a salt and/or wax and/or flour coating, or other suitable coating materials.
The coating may be applied in an amount of at least 0.1%by weight of the core, e.g., at least 0.5%, 1%or 5%. The amount may be at most 100%, 70%, 50%, 40%or 30%.
The coating is preferably at least 0.1 μm thick, particularly at least 0.5 μm, at least 1 μm or at least 5 μm. In some embodiments the thickness of the coating is below 100 μm, such as below 60 μm, or below 40 μm.
The coating should encapsulate the core unit by forming a substantially continuous layer. A substantially continuous layer is to be understood as a coating having few or no holes,  so that the core unit is encapsulated or enclosed with few or no uncoated areas. The layer or coating should in particular be homogeneous in thickness.
The coating can further contain other materials as known in the art, e.g., fillers, antisticking agents, pigments, dyes, plasticizers and/or binders, such as titanium dioxide, kaolin, calcium carbonate or talc.
The granule may comprise a core comprising the polypeptide having catalase activity of the invention, one or more salt coatings and one or more wax coatings. Examples of enzyme granules with multiple coatings are shown in WO1993/07263, WO1997/23606 and WO2016/149636.

EXAMPLES
Example 1: Heat Stress Model in Broilers: SOD and CAT reduce oxidative stress response
Background
Different stress factors inevitably influence the animal’s physiology and performance with varying degrees during the production period. High ambient temperature is one of the most common stressor in modern poultry production resulting in reduced feed intake, body weight gain, and increased mortality. Because of their physiological state and greater metabolic activity, broilers are more susceptible to temperature –associated environmental challenges. In addition to its effect on bird performance, the adverse effects of heat stress can range from minimal discomfort to multi-organ damage and failure, including alteration of gut permeability and function due to weakened tight junctions of the epithelial layer. Therefore, heat stress-induced disturbance of gut integrity may lead to leaky gut syndrome thus increasing the susceptibility of birds to enteric pathogens that may lead to systemic bacterial infections. Moreover, heat stress can cause oxidative damage by increasing the formation of reactive oxygen species.
Hypothesis and objective
The central hypothesis is that the adverse effects of heat stress on performance and health of chickens can be mitigated by incorporating effective feed additives into poultry diets. Certain  compounds that can alter the dysregulating effects of heat stress may help in maintaining gut integrity and function. Therefore, the main objective is to alleviate the impact of heat stress challenge on performance and overall health of broilers by timely supplementation of non-drug dietary additives.
Experimental design
A 35-day trial with only male broiler chicks will be run in floor pens with eight replicate pens per treatment and 20 birds/pen. Birds are randomly assigned to treatment groups in a 2 x 4 factorial arrangement that includes heat stress (optimal or high heat) and dietary treatments (basal diet or feed additives) as per Figure 1. A total of 4 animal rooms are used (2 controls and 2 heat stress) each housing half the replicate pens (n = 4) per group.
Three birds per pen for each of the three sampling times (3 x 3 = 9) are randomly tagged at placement with necktags of different colour (or number) per sampling time to ensure random sampling. At sampling, the two of the three birds with the closest to average BW are selected for sampling and their BW is recorded. If less than two of those birds are available or healthy, other random birds can be selected in the pen to complete the two sampled birds.
Treatment groups including controls and challenge from d 28 to 35 (heat stress) are as follows:

Handling of Products
● Store refrigerated at 4 C.
● Gently mix before applying.
● Use industrial protective equipment for handling: gloves, mask, googles, and coat.
● Mix with distilled water at room temperature to complete 1,000 ml /MT immediately before application, and spray uniformly in the mixer, directly into the feed with a micro-fluid nozzle applicator.
Heat Stress Protocol
Heat stress protocol is performed as planned during the finisher feeding phase (d 28 to d 35) . For the heat stress groups, temperature is maintained at 35 ± 1℃ (10℃ above the recommended temp. ) and applied once daily from 10 am to 2 pm, then reduced again to 25 C +/-1 for the remainder of the day. Relative humidity is monitored and maintained at RH < 50%. Birds in the separate ‘optimal heat’ group are kept under normal constant recommended temperatures (25℃ +/-1) . The birds’ (2 birds/pen) rectal temperature was monitored daily with a rectal probe during the heat stress period (d 28-35) .
Feed
The diets consist of corn/soybean in mash as Starter (d 1-21) and Grower (d 22-35) and will be formulated according to commercial specifications for the broilers used (Ross or Cobb) to meet or exceed NRC recommendations (Table 4) . Test products are sprayed onto a small amount (20 kg) of the basal diet and mixed with the rest of the batch for each diet.

Parameters evaluated
1. Performance: Standard performance parameters including body weight (BW) , weight gains (BWG) , feed intake (FI) , and feed conversion ratios (FCR) are evaluated on days 10, 21, 27, and 35 on a per pen basis. Any mortality is recorded daily and feed consumption (+ FCR) corrected for accordingly. Average bird performance is calculated based on the number of birds per each pen (i.e. replicate) after adjusting for any mortality.
2. Rectal temperature: The birds’ rectal temperature is monitored daily during the heat stress period (d 28-35) . Two birds from each replicate pen are selected and tagged for body temperature measurement using a rectal probe daily at a pre-set time range (e.g. 1-2 pm) .
3. Antioxidant parameters: Based on the stress challenge employed, blood serum and liver are sampled at 27, 28 and 35 d from two birds of average BW per pen to determine parameters related to oxidative stress:
a. MDA, CAT, GSH-Px, and SOD: On d 27, two birds per replicate pen are tagged for blood sampling. Blood samples are taken by wing venipuncture on d 27, d 28, and d 35 (alternating sides) , and collected into red-topped serum tubes. The tubes are transferred to the main lab and centrifuged at 2,000 x g for 5 min to collect sera, which are stored at –20℃ until analysis. Antioxidant analyses in blood samples are carried out with commercial kits according to the manufacturer recommendations.
b. Optional analyses. Depending on the results of the other parameters, it might be decided to measure Vitamin E, vitamin A, cysteine, cystine, methionine, and glutamine in the liver, using standard HPLC protocols are used to measure vitamins A and E, as well as profile amino acids (separated on a single column) . They are not included in the initial budget.
4. Liver bacterial load: At the end of the study (d 35) , liver samples are collected from one bird per pen in sterile sampling bags to determine total bacterial load in liver. To establish standard curves for bacterial quantification, pure bacterial (E. coli, and Clostridium perfringens) suspensions are individually cultured in corresponding selective media, the DNA extracted (commercial extraction kits) , and its concentration determined (Nano-Drop) . The DNA stocks are serially diluted (6 times) and real time quantitative PCR performed to determine the threshold cycle (Ct) value related to each pure sample. The standard curves are established with the DNA concentrations and corresponding relative Ct values. DNA from liver tissue samples are extracted via special kits. The abundance of DNA copies in DNA samples from liver tissue is determined by qPCR. For this purpose, specific primers for bacterial 16S rRNA gene are used, and the bacterial loads per gram tissue are calculated using the generated standard curves.
5. Carcass/body composition (no additional cost) : Dual Energy X-Ray Absorptiometry (DXA) analysis is performed on 3 birds per pen on d 35 to assess the effects of products on various measurements of carcass/body composition. These include body fat percentage, fat tissue, lean tissue, and bone mineral density (BMD) , in addition to bone mineral content (BMC) and carcass area, both used for calculation purposes.
6. Gene expression: Liver and intestinal (jejunum) tissue samples are taken (2/pen) on d 27, d 28 and d 35 from birds with average pen weight (sampled above for histology) . Liver weight is measured and relative weight calculated per bird. Tissues are collected, minced, snap-frozen, and stored at –80℃ until qPCR analysis. Target genes to be measured include  immunity-related to heat stress (oxidative stress, heat shock proteins, inflammatory markers) , tight junction genes, host defense peptides, and nutrient transporters. The final list of targets is determined based on study outcome. Transcript analysis for a subset of targets is measured in each collected tissue.
Heat Stress Protocol
Heat stress protocol was performed as planned during the last week of the experiment (d 28 to d 35) . For the heat stress groups, temperature was raised and maintained at 35 ± 1 ℃ (10 ℃ above the recommended temp. ) and applied once daily from 10am to 2pm, then reduced again to 25 ℃ +/-1 for the remainder of the day. Relative humidity was monitored and maintained at RH < 50%. Birds in the separate ‘optimal heat’ group were kept under normal constant recommended temperatures (25 ℃ +/-1) . The birds’ (2 birds/pen) rectal temperature was monitored daily with a rectal probe during the heat stress period (d 28-35) .
Sampling Procedures
Blood, liver and intestinal (jejunum) tissue samples were taken on d 27 (1/pen) , d 28 (2/pen) and d 35 (2/pen) from birds with average pen weight for qPCR and antioxidant assay analyses. The livers were weighed and observed for any pathological findings.
DXA Analysis
Dual Energy X-Ray Absorptiometry (DXA) analysis was performed on 2 birds per pen on d 35 to assess various measurements of carcass/body composition. Birds were individually wing-banded, sacrificed by cervical dislocation and subsequently defeathered and carcasses stored at –20℃ until DXA analysis. Birds were thawed and 10 birds were scanned at a time using GE Healthcare Lunar Prodigy Advance, System ID PA+130, 744 (GE, Madison, WI) .
Total RNA Extraction and Reverse Transcription
Total RNA was extracted from individual liver and intestinal tissues using the Direct-zol RNA Kits (Zymo Research) according to the manufacturer’s recommendations. Tissue samples were removed from –80℃ and placed on ice. A 20-30 mg aliquot of each sample was weighed, placed into a 2-mL microcentrifuge tube, and kept on ice until homogenization. Total RNA concentration was determined at optical density (OD) of 260 (NanoDrop-1000, Thermo Fisher Scientific, Waltham, MA) , and RNA purity was verified by evaluating the 260/280 OD ratios. Total RNA was diluted to 0.2 μg/μL in nuclease-free water. Reverse transcription was accomplished using the high capacity cDNA Reverse Transcription kit (Applied Biosystems, Carlsbad, CA) following the manufacturer’s protocol and the cDNA was stored at –20℃.
Quantitative Real-Time PCR
Quantitative real-time PCR (qRT-PCR) was performed using an ABI 7500 Fast Real-Time PCR System (Applied Biosystems) . The cDNA was diluted 1: 20 in nuclease-free water, and 1 μL of the diluted cDNA was added to each well of a 96-well plate. Next, 9 μL of RT-PCR master mix containing 5 μL of Fast SYBR Green Master Mix (Applied Biosystems) , 0.5 μL each of 2 μM forward and reverse primers, and 3 μL of sterile nuclease-free water per reaction were added to  each well for a final volume of 10 μL. During the PCR reaction, samples were subjected to an initial denaturation phase of 95℃ for 20 s followed by 40 cycles of denaturation at 95℃ for 3 s and annealing and extension at 60℃ for 30 s. Gene expression was analyzed using glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as an endogenous control. Each reaction was run in duplicate. Results from qRT-PCR were analyzed using the 7500 Real-Time PCR software (Applied Biosystems) . The primer pairs used are shown in Table 4. Average gene expression relative to the GAPDH endogenous control for each sample was calculated using the 2 –ΔΔCt method (Livak and Schmittgen, 2001) .
Antioxidant Analysis
Based on the stress challenge employed, blood serum and liver samples were analyzed to determine thiobarbituric acid reactive substances (TBARS) , catalase (CAT) , glutathione peroxidase (GPx) , and superoxide dismutase (SOD) activities on d 27, d 28 and d 35. Antioxidant analyses were carried out with commercial assay kits (Cayman, Ann Arbor, MI) .
Statistical Analysis
Data were subjected to a 2-way ANOVA using the GLM procedure of JMP (Pro13) . The models included heat stress (optimal and high heat) and dietary treatments (basal diet or feed additives) as the main factors, and the 2-way interactions. Post hoc testing was only carried out for significant interactions and was performed using simple effect analysis. The probability P <0.05 was considered significant unless otherwise noted.

● There was an effect of SOD 400 + CAT 100 on BW gain and feed intake in the overall period.
● A high performance effect of enzymes on BWG and FCR was present in the first week. As reported in Figures 7 &8, body weight gain (BWG) and feed conversion ratio (FCR) were improved in birds fed the diets containing either Pro. Low (T3&T7) or Pro. High (T4&T8) compared to birds fed the control diet.
● Feed intake (FI) and mortality were not affected among the treatment groups during the first week (d 0-7) . In particular, a numeric reductions in mortality during heat stress and over the entire trial could be observed.
● Birds fed the diets containing Vit E+Se, Pro. Low, and Pro. High had higher Feed intake compared to the control group and also tended to have higher BWG between d 7-14. Similarly, BW and FI were higher in birds fed those diets containing Vit E+Se, Pro. Low, and Pro. High between d 0-14.
● Birds fed antioxidant enzymes or Vit E &Se did not perform better during heat stress. However, numerically there was less mortality in birds fed antioxidants (enzymes or Vit E&Se) compared to the control during HS.
The data presented above show that an animal feed additive comprising at least one or more polypeptides according to the present invention improves one or more performance parameters selected from the group consisting of
● Feed Conversion Ratio (FCR) ,
● Growth Rate (GR) , Body Weight Gain (WG) ,
● Mortality Rate (MR) .
Other Parameters:
With respect to markers for oxidative and cellular stress and immune function a significant interaction was observed in the HSP90 gene expression between dietary and heat stress treatments. In particular,, the heat challenge significantly upregulated the expression of GPx, SOD, HSP70, HSP90, and TLR4, and downregulated that of GST, IL-10, TNFα, and IFNγ in the liver on d 27/28.
A) Liver Gene Expression
The dietary treatments had significant increase in liver GPx (pre-heat stress) with the lowest doses of enzymes (Figure 9 - liver GPx, nmol/min/mL (measured day 27) )
B) Measurement of heat shock proteins (HSP) , which are indicators of cellular stress.
With respect to HSP
● a significant reduction of jejunum gene expression of HSP70 (Figure 10 - (day 28) ) and liver gene expression of HSP70 (Figure 11– (day 35) ) during heat stress at the lowest dose of enzymes and
● a numeric reduction in liver gene expression of HSP90 during heat stress was observed.
C) Immune function.
The enzyme according to the present invention also show a positive effect on immune function. The treatments show a significant reduction of liver iNOS prior to heat stress challenge (Figure 12 –liver iNOS (mediator of inflammation) pre-heat stress (d 27) ) or TLR2, IL-1 B, IL-10, TNFa, and INFy (Figure 13 –liver gene expression of IL-10 (anti-inflammatory) during heat stress (d 35); Figure 14 –liver gene expression of TNF alpha (pro-inflammatory) during heat stress (d 35); Figure 15 –liver gene expression of INF gamma (pro-inflammatory) during heat stress (d 35) ) .
The results on all these other parameters clearly show that the enzymes according to the present invention help
● to reduce
○ heat-, cold-, nutritional-and oxidative stress,
○ cellular markers of reactive oxygen species or free radicals,
○ inflammation and
● to improve or enhance immune response in the animal.

Summary
The effect of antioxidant enzymes (SOD and CAT) alone at different doses and in combination on the growth performance of early weaned piglets was evaluated in a trial run. A total of eight treatments were tested during the study: 6 test groups: SOD (Product A, SEQ ID No. 1 at 1250 and 2500 U/kg) , CAT (Product B, SEQ ID NO 7 and Product C, SEQ ID NO 250 at 100 U/kg)  and 2 combinations (A500 U/kg + B 100 U/kg; and A 500 U/kg + B 100 U/kg) ; were compared against a Positive Control feed (fed with Avilamycin at 90.7 g/lb) and a Negative Control (standard ration) . Each of treatments contained 12 replicates per treatment randomly assigned and containing 5 male piglets per replicate for a total number of 480 animals on study. Piglets were randomly assigned to treatments on Trial Day 0 (post-weaning at 21 days of age) . At 42 days of age, live performance (growth weight gain and feed conversion) was determined. All rations were formulated with an increase of approximately 5-6%additional crude protein above normal commercial levels. Blood samples were collected at  day  0, 14 and 42 to evaluate oxidative stress parameters at DSM. Gut tissue samples at the duodenum and ileum to evaluate gene expression linked to oxidative stress, and intestinal content (ileum and caecum) , to study the microbiome population, were collected from 12 animals at the beginning of the trial (baseline) and one animal per pen (12 piglets x 8 treatments) at day 14 and at day 42.
For the entire grow-out period (Days 0-42) , body weight gain showed significant improvement over the Negative Control group when piglets were fed diets containing 2000 U/kg of SOD (Product A) , 100 U/kg of CAT B, and both combination of 400 U/kg of SOD (Product A) with 100 U/kg of both CAT products B &C, with the greatest improvements coming with the combination of 400 U/kg of SOD with 100 U/kg of CAT B, which also performed statistically similar to the Positive Control ration that contained Avilamycin at 90.7 g/lb. Feed conversion improved significantly between Positive Control and Negative Control.
Test System
The commercial-simulated test model employed in this study used piglets reared under a normal swine industry Starter diet (Trial Day 0-21) and Grower diet (Trial Day 21-42) , reared on slatted floors. Ration formulations were conducted via computer-generated linear regression program that simulates formulations conducted during practical swine production techniques. Treatments were tested in male piglets. Piglets were continuously fed their experimental diets from time of placement on Trial Day 0 to Trial Day 42.
Table 9: Treatments
Figure PCTCN2020083409-appb-000034
Figure PCTCN2020083409-appb-000035
Piglets were weighed and randomly placed into each pen on Trial Day 0 and fed their respective diets. Each pen had sufficient floor density, feeder and waterer space for each grow-out area for the piglets. Following 42 days of grow-out, piglets were weighed, feed consumption determined, and feed conversion (feed consumed/body weight) calculated.
Materials and Methods
Experimental Design
A total of 500 male piglets (asufficient number to ensure availability of at least 480 healthy male piglets for the conduct of the study) were obtained from a swine breeder on Trial Day 0 (upon weaning, when the piglets were 21 days of age) . Piglets were fed their respective treatment feed ad libitum from Trial Day 0 to Trial Day 42.
Housing and Daily Observations
Each experimental test unit of swine pens was housed in separated pens, located in a room containing forced air heaters with a cross-house ventilation system. Piglets were placed in a 6 ft x 6 ft pen floor area with a minimum of 9.0 ft 2 per piglet (without feeder and waterer space) provided. At least two nipple drinkers per pen (via well water) provided water. Piglets were observed daily for overall health, behavior and/or evidence of toxicity, and environmental conditions. Temperature in the test facility was checked daily. Drinking water and feed were confirmed to be provided ad libitum. No type of medication (other than test material) was administered during the entire feeding period.
Data and Observations
Live performance body weights and feed intakes were collected on  Days  0, 14, 21, and 42 during the growing period. Weight gain, feed intake, feed: gain ratio (feed efficiency) were calculated for 0-42 days of age between weaning and Trial Day 42. Differences between piglets fed control and test groups were statistically evaluated at P<0.05 in a typical ANOVA analysis of variance test model, employing Treatment x Replicate RCB (Randomized Complete Block) . Control group was considered to be the following: Treatment 2, containing Avilamycin at 90.7 g/lb.
At the end of the study, all piglets were humanely euthanized and were disposed of according to local regulations via on-farm composting techniques.
Diet and Water Administration
Diets were fed in two feed phases: Starter diet (0-21 days of age) and Grower diet (21-42 days of age) . All diets were offered ad libitum, without restriction. Fresh well water (from the research facility deep well) was provided ad libitum.

Results
For the entire grow-out period (Days 0-42) , body weight gain (Figure 18) showed significant improvement over the Negative Control group (no added test materials) when piglets were fed diets containing 2000 U/kg of Product A, 100 U/kg of Product B, and a combination of 400 U/kg of Product A with 100 U/kg of both Product B and Product C, with the greatest improvements coming with the combination of 400 U/kg of Product A with 100 U/kg of Product B, which also performed statistically similar to the Positive Control ration that contained Avilamycin at 90.7 g/lb. As shown in Figure 19, feed conversion improved between Treatment 2 (Positive Control) and Treatment 1 (Negative Control) over the period of d0-d42. In particular, inclusion of SOD + CAT (independently of the candidate B or C) in the ratio 400: 100 U/kg showed significant improvement on FCR performance.
In conclusion, the use of a combination of 80 ml/MT of Product A and either 4 ml/MT or 20 ml/MT of Product B appeared to significantly improve 0-42 days of age body weight gains and feed conversion as compared to a standard control ration. Therefore, when commercial piglets are grown on concrete slat floors, this combination appears to have the great potential to result in better live performance.
Analysis and calculation of body weight coefficient of variation at day 14 shows a significant effect of the treatment according to the invention on CV of BW. The data is shown in table 11. The results show that the enzymes according to the invention improve flock uniformity compared to the control T1.

Example 4: Effect of antioxidant enzymes (SOD and CAT) alone or in combination on plasmatic antioxidant enzymes, oxidative stress index and intestinal gene expression response of weaned piglets (based on animal trial of example 3) .
Summary
The objective of this study was to evaluate anti-oxidant enzymes supplementation (SOD and CAT) alone and in combination in early weaned piglets, and if these enzymes can potentially alleviate the oxidative stress impact on weaned piglets and consequently improve the growth performance. In the in vivo trial (example 3) , plasma samples were collected at day 0 (baseline, weaning moment) , day 14 and day 42 of the study for additional analysis.
Piglets supplemented with CAT alone showed a significant increase in the plasmatic antioxidant activity (PAT) . At day 42, also piglets supplemented with CAT showed a significant increase of GPx activity. Gene expression showed significant modulation at day 14. In duodenum at day 14, the supplementation of antioxidant enzymes (SOD + CAT) showed a downregulation of the genes that encode NQO1 (protecting the cells against Oxidative Stress OS) and the anti-oxidant enzyme GSTP1 (p=0.07 and p=0.005 respectively) suggesting that diet supplementation with a combination of SOD and CAT decreases stress protein expressions at the beginning of small  intestine of weaned piglets. SCARA3 showed also a significant increase in the same group (p=0.003) , avoiding accumulation of ROS. At the duodenum, the gene that encodes the antioxidant enzyme GPX1 showed a significant upregulation in piglets supplemented with CAT alone compared to control group and those results are in agreement with the GPx plasmatic activity found. And at the ileum level, supplementation of CAT and SOD alone showed a upregulation on the protecting protein NQO1 but a downregulation on HSP70, and piglets supplemented with SOD + CAT showed a downregulation on the genes NOX5, oxidative stress marker, and CAT, antioxidant enzyme. Those data provide evidence that diet supplementation with a SOD, CAT and the combination of both enzymes, potentially decrease oxidative stress status in weaned piglets.

GAPDH glyceraldehyde-3-phosphate dehydrogenase
The thermal cycling was run on Light Cycler 96 (Roche Diagnostics, Meylan, France) with the following program: 95℃ 10 min, followed by 40 cycles of denaturation at 95℃ 15 seconds and hybridization/elongation at 60℃ 1 min. The Delta Ct method was used to determine expression of target genes (Livak and Schmittgen, 2001)
Oxidative stress index: FRAS5
An oxidative stress index was calculated as the ratio of reactive oxygen metabolites (ROM) and Plasma antioxidant capability (PAT) determined in plasma and liver lysate samples. ROM and PAT were analyzed using commercially methods (d-ROM fast test and PAT test) on FRAS5 instrument (Innovatics Laboratory, Philadelphia, USA) . For d-ROM test, 10 μL of sample was mixed with an acidic buffer. Then, a chromogen was added, and measured photometrically at 505 nm. The results are expressed in UCarr (1 UCarr = 0.08 mg of H2O2/dl) . For PAT test, 10 μl of sample was added in a colored solution (mix of source ferric ions and chromogen) . The intensity of chromatic change was measured at 505 nm. The results are expressed in UCor (1 UCor = 1.4 μM of Vitamin C equivalent) . The oxidative stress index was calculated as the ratio of d-ROMs test value to PAT test value.

Results
Plasmatic parameters
Results of the plasmatic parameters (SOD, CAT and GPx, OS) at  day  0, 14 and 42 can be summarized as follows:
● At day 14, the plasmatic activity of the antioxidant enzymes SOD, CAT and GPx were higher than at day 0.
● For the GPx activity, at day 42, the addition of the enzymes in the diet showed a significant increase in group receiving either the CAT alone or in combination with the SOD.
● At day 0, the reactive oxygen metabolites (d-ROM) and the OSI were higher than at day 14 and 42, reflecting the level of response to the stress generated in the early weaning period of the animals, and indicating a higher sensitivity of this biomarker in acute stress compared to the activity of SOD and CAT.
● Interestingly, the d-ROM showed an increase in animals supplemented with CAT or CAT+SOD in both time point.
● At day 14, the plasmatic antioxidant capacity showed a significant difference between experimental groups (p<0.0001) with an increase in group supplemented with CAT or SOD+CAT.
Gene expression targeting oxidative stress
Results of the gene expression analysis are shown in Table 16 (Gene expression fold change of oxidative stress related genes in duodenum at day 14) , Table 17 (Gene expression fold change of oxidative stress related genes in ileum at day 42) and can be summarized as follows:
● In the group supplemented with both enzymes (SOD + CAT) , a downregulation of the genes that encode NQO1 (protecting the cells against OS) and the anti-oxidant enzyme GSTP1 (p=0.07 and p=0.005 respectively) was observed suggesting that diet supplementation with a combination of SOD and CAT decreases stress protein expressions at the beginning of small intestine of weaned piglets.
● SCARA3 showed also a significant increase in the same group (p=0.003) , avoiding accumulation of ROS.
● In duodenum at day 42, only the gene that encode the antioxidant enzyme GPX1 gene showed a significant upregulation (p=0.019) in piglets supplemented with CAT alone compared to control group with a fold change of 1.34. Those results are in line with the GPx plasmatic activity found in the piglets after 42 days of supplementation.
● Piglets supplemented with SOD alone showed a upregulation on the protecting protein a NQO1
● Similarly to SOD supplementation alone, piglets supplemented with CAT alone showed an upregulation of NQO1. Besides that, piglets showed a upregulation on antioxidant enzyme GSTP1 and a downregulation of a redox marker NOX5.
● Finally, piglets supplemented with SOD + CAT showed a downregulation on the genes NOX5, oxidative stress marker, and CAT, antioxidant enzyme.

Conclusion
Plasmatic antioxidant enzymes, specially SOD and CAT, showed a clear increase at day 14, independently of the treatment, indicating that the oxidative stress situation induced by piglet weaning is progressively corrected during the postweaning period. A significant increase in the plasmatic antioxidant activity in piglets supplements with CAT alone could be observed. At day 42, piglets supplemented with CAT showed a significant increase of GPx activity.
Gene expression showed significant modulation at day 14 and not at day 42. In duodenum at day 14, the supplementation of antioxidant enzymes (SOD + CAT) showed a downregulation of the genes that encode NQO1 (protecting the cells against OS) and the anti-oxidant enzyme GSTP1 (p=0.07 and p=0.005 respectively) suggesting that diet supplementation with a combination of SOD and CAT decreases stress protein expressions at the beginning of small intestine of weaned piglets. SCARA3 showed also a significant increase in the same group (p=0.003) , avoiding accumulation of ROS.
At the duodenum, only the gene that encode the antioxidant enzyme GPX1 showed a significant upregulation in piglets supplemented with CAT alone compared to control group and those results are in agreement with the GPx plasmatic activity found at 42 days. And at the ileum level, supplementation of CAT and SOD alone showed a upregulation on the protecting protein NQO1 and piglets supplemented with SOD + CAT showed a downregulation on the genes NOX5, oxidative stress marker, and CAT, antioxidant enzyme. Those data provide evidence that diet supplementation with a SOD, CAT and the combination of both enzymes, potentially decrease oxidative stress status in weaned piglets.

Cloning, expression and fermentation of fungal SOD enzymes
The SOD genes were derived from fungal strains isolated from environmental samples using standard microbiological isolation techniques. The donor strains HEAL7057, HEAL7058 and HEAL7059 were identified, and taxonomy assigned based on the DNA sequencing of the ITS (Table 1) . The donor fungal organism for HEAL7007 was Trichoderma reesei QM6a, a publicly available strain originally isolated from the Solomon Islands and is available in collections such as ATCC (ATCC 13631) .
Chromosomal DNA from individual strains was isolated by QIAamp Dneasy Kit (Qiagen, Hilden, Germany) . 5 μg of each genomic DNA sample were sent for full genome sequencing using Illumina technology. Genome sequencing, the subsequent assembly of reads and the gene discovery (i.e. annotation of gene functions) is known to persons skilled in the art and the service can also be purchased commercially.
The genome sequences were BLAST analyzed for putative SOD from the PFAM database families PF00080. This analysis identified genes encoding putative SOD, which were subsequently cloned and recombinantly expressed in Aspergillus oryzae.
The SOD genes were amplified by PCR respectively from above isolated genomic DNA. The purified PCR products were cloned into the previously digested pDau109 by ligation with an IN-FUSION TM CF Dry-down Cloning Kit (Clontech Laboratories, Inc., Mountain View, CA, USA) according to the manufacturer's instructions. The plasmid pDAu109 and its use are described in (WO 2005/042735) . The ligation mixture was used to transform E. coli TOP10 chemically competent cells (described in Strains) . The cloned genes were sequenced and confirmed to be identical to the corresponding genes found in the genome sequences and transformed into the Aspergillus oryzae strain MT3568 (WO 11/057140) by the methods described in Christensen et  al., 1988, Biotechnology 6, 1419-1422 and WO 04/032648. Transformants were selected during regeneration from protoplasts based on the ability, conferred by a selectable marker in the expression vector, to utilize acetamide as a nitrogen source, and were subsequently re-isolated under selection.
Production of the recombinant SOD peptides was evaluated by culturing the transformants in 96-well deep-well microtiter plates for 4 days at 30℃ in either a 0.25ml or 0.75ml volume of either or both YPG medium (WO 05/066338) or DAP-4C-1 medium (WO 12/103350) and monitoring peptide expression by SDS-PAGE. A single Aspergillus transformant was selected for each gene based on expression yields as evaluated in microtiter plate fermentation.
Spores of the best expressed transformant were spread on COVE-2 plates for re-isolation in order to isolate single colonies. Then a single colony was spread on a COVE-2 tube until sporulation.
For larger-scale production of the recombinant enzymes, and the Aspergillus transformants were cultured in 500ml baffled flasks containing 150 ml of fermentation medium. Transformants expressing the SOD peptides were fermented in DAP-4C-1 medium (WO 12/103350) . The cultures were shaken on a rotary table at 150 RPM at for 4 days, and the broth was subsequently separated from cellular material by passage through a 0.22 um filtration unit.
Example 8 SOD Purification
The purification process for SOD was firstly applied with hydrophobic interaction chromatography, then if needed, ion exchange chromatography was applied. The difference for all the molecules was buffer type, pH, and salt concentration.
The culture supernatant of recombinant SOD was firstly added by ammonium sulfate with a final concentration of 2.2M and loaded into Phenyl Sepharose High Performance (GE Healthcare) equilibrated with 20mM Tris-HCl at pH7.0 with 2.2M ammonium sulfate added. A gradient decrease of ammonium sulfate concentration from 2.2M to 0 was set up as elution condition. The elution fractions and flow-through faction were assayed by SDS-PAGE. The SOD activity was determined by the relative activity method of the SOD activity assay kit from Sigma (Cat No. 19160) described as below.
If the purity of enzyme purified by first step was not good and contains several bands, ion exchange chromatography will be applied for further purification. The fractions with SOD activity were pooled together and dialyzed with 20 mM Tris-HCl at pH7.0, then loaded into a Mono Q or Capto Q column (GE Healthcare) equilibrated with 20 mM Tris-HCl pH7.0. A gradient increase of NaCl concentration from 0 to 1 M with 20 mM Tris-HCl at pH7.0 was set up  as elution buffer. The elution fractions and flow-through fraction were assayed for SDS-PAGE and SOD activity.
The fractions with enzyme activity were pooled together and then diafiltrated with 20mM Tris-HCl at pH7.0. The protein concentration was determined by

Protein Assay Kit (Invitrogen, cat Q33212) .
Example 9 SOD Activity assay
SOD activity was determined using the relative active method of the SOD activity assay kit from Sigma (Cat No. 19160) . 20μl SOD with different dilution times by MQ water and 0.01%Triton X-100 was added into 200μl WST solution (prepared as described for SOD activity assay kit) , then 20μl coupled enzyme solution from kit was added. The mixture was measured at 450nm for 20 minutes at 37℃ (interval 40sec, shake before first read) . One slope could be created with mOD/min vs enzyme dosage, which could be set as standard curve for each SOD. Two commercial SODs from
Figure PCTCN2020083409-appb-000062
recombinant SOD bovine expressed in Escherichia coli (S9697) with 6108U/mg EP and SOD from E. coli (S5639) with 10240U/mg EP were set as specific activity reference.
Since the pH of WST working solution was about 10, the SOD activity at alkaline condition might be very low. The SOD activity assay was later adjusted by at pH7.8, which WST solution was replaced by Cytochrome C solution at pH7.8 (Cytochrome C, Sigma-Aldrich C7752) . The Cytochrome C working solution contains 50mM PBS at pH7.8, 0.1 mM EDTA, 0.01 mM CytoC, and 0.05mM Xanthine (Sigma-Aldrich X0626) . The absorbance of mixture was measured at 550nm.
Example 10 Gastric stability assay of SODs
Gastric stability was assayed with artificial gastric juice as stress condition. 20μl SOD with appropriate dilution was added into 180μl stress buffer (100mM NaCI, 0.0013M HCI at pH3.0) . The stress buffer with pepsin was prepared by adding 1.11 mg/ml pepsin (from porcine gastric mucosa, P7000, Sigma, 474U/mg) . The mixture was incubated at 37℃ in thermomixer for 0, 15, 30, 45, 60, 90, and 120 minutes separately. 10μl sample extracted from the mixture was added into 90μl activity buffer (K 2HPO 4/KH2PO4 mixed with final concentration of 100mM PBS at pH7.0) as stop mixture. Then 20μl stop mixture was added into 200μl WST solution (or CytoC solution at pH7.8) , and finally 20μl coupled enzyme solution from kit was added to measure absorbance. The absorbance was measured at 450nm for Sigma SOD kit (or 550nm at pH 7.8) for 20 minutes at 37℃ (interval 40sec, shake before first read) . The activity at pH7.0 without stress condition was set as reference, and the residual activity at stress condition (pH3.0, pH3.0+pepsin) compared with reference was calculated as relative stability.

As can be seen from the Table, the SODs of the invention are surprisingly gastric stable compared to conventional and commercial SODs.
Example 11 Thermal stability assay of SODs
Thermal stability was quantified utilizing nano differential scanning fluorimetry (nDSF) . To adjust pH, the samples were diluted 10-fold in a buffer cocktail containing 50 mM 2- (N-Morpholin) ethansulfonsyre (MES) , 50 mM glycine, 50 mM acetic acid, pH 3-11. Sample dilutions were conducted using a Hamilton Microlab STAR Liquid Handling System in 96-well microtiter plates and transferred to 384-well microplates. The nDSF experiments were conducted utilizing either a Prometheus NT. 48 or Prometheus NT. Plex with autosampler from Nanotemper. With the Prometheus NT. 48, the samples were loaded manually using single capillaries (PR-C002) , while samples were loaded in the Prometheus NT. Plex using capillary chips (PR-AC002) . The experiments were conducted from 20 to 95 ℃ with a temperature gradient of 3.3 ℃/min. The transition temperatures (T m-values) were obtained from peak values derived from the first-derivative of the signal trace (350/330 nm fluorescence ratio or 330 nm fluorescence) using PR.ThermControl software.

Example 12: Cloning, expression and fermentation of fungal catalase enzymes
The catalase genes were derived from fungal strains isolated from environmental samples using standard microbiological isolation techniques. The donor strains HEAL7001, was identified, and taxonomy assigned based on the DNA sequencing of the ITS (Table 1) . The donor fungal organism for HEAL7060 was Curvularia verruculosa, a publicly available strain originally isolated from a grass inflorescence in The Gambian Republic, Africa. The strain was originally collected in 1966: Curvularia verruculosa Tandon &Bilgrami ex M. B. Ellis, Mycological Papers 106: 20 (1966) .
Chromosomal DNA from individual strains was isolated by QIAamp Dneasy Kit (Qiagen, Hilden, Germany) . 5 μg of each genomic DNA sample were sent for full genome sequencing using Illumina technology. Genome sequencing, the subsequent assembly of reads and the  gene discovery (i.e. annotation of gene functions) is known to persons skilled in the art and the service can also be purchased commercially.
The genome sequences were BLAST analyzed for putative catalase from the PFAM database families PF00199 and PF18011. This analysis identified genes encoding putative catalases, which were subsequently cloned and recombinantly expressed in Aspergillus oryzae.
The catalase genes were amplified by PCR respectively from above isolated genomic DNA. The purified PCR products were cloned into the previously digested pDau109 by ligation with an IN-FUSION TM CF Dry-down Cloning Kit (Clontech Laboratories, Inc., Mountain View, CA, USA) according to the manufacturer's instructions. The plasmid pDAu109 and its use are described in (WO 2005/042735) . The ligation mixture was used to transform E. coli TOP10 chemically competent cells (described in Strains) . The cloned genes were sequenced and confirmed to be identical to the corresponding genes found in the genome sequences and transformed into the Aspergillus oryzae strain MT3568 (WO 11/057140) by the methods described in Christensen et al., 1988, Biotechnology 6, 1419-1422 and WO 04/032648. Transformants were selected during regeneration from protoplasts based on the ability, conferred by a selectable marker in the expression vector, to utilize acetamide as a nitrogen source, and were subsequently re-isolated under selection.
Production of the recombinant catalase peptides was evaluated by culturing the transformants in 96-well deep-well microtiter plates for 4 days at 30℃ in either a 0.25ml or 0.75ml volume of either or both YPG medium (WO 05/066338) or DAP-4C-1 medium (WO 12/103350) and monitoring peptide expression by SDS-PAGE. A single Aspergillus transformant was selected for each gene based on expression yields as evaluated in microtiter plate fermentation.
Spores of the best expressed transformant were spread on COVE-2 plates for re-isolation in order to isolate single colonies. Then a single colony was spread on a COVE-2 tube until sporulation.
For larger-scale production of the recombinant enzymes, and the Aspergillus transformants were cultured in 500ml baffled flasks containing 150 ml of fermentation medium. Transformants expressing the catalase peptides were fermented in DAP-4C-1 medium (WO 12/103350) . The cultures were shaken on a rotary table at 150 RPM at for 4 days, and the broth was subsequently separated from cellular material by passage through a 0.22 um filtration unit.

Enzyme Commission (EC) Number: 1.11.1.6, CAS Number: 9001-05-2, Molecular weight: 250 kDa) has an acitivty of 3524 U/mg EP. Catalase activity was determined by H 2O 2 reduction detected at 240nm. Firstly, catalase was  diluted with different dilution times by MQ water and 0.01%Triton X-100.10μl enzyme sample, 90 μl activity buffer (K 2HPO 4/KH 2PO 4 mixed with final concentration of 100mM PBS at pH7.0) were added into 50μl 0.2%H 2O 2 solution (30%H 2O 2 was diluted to 0.2%in activity buffer) . The mixture was measured at 240nm for 10 minutes at room temperature (interval 34sec, shake before first read) . The commercial catalase from
Figure PCTCN2020083409-appb-000066
catalase from bovine liver (C1345) , was set as reference. This allows for the selection of the suitable enzyme dosage.

Example 14: Gastric stability assay for catalase
Gastric stability was assayed with artificial gastric juice as stress condition. 10μl catalase with appropriate dilution was added into 90μl stress buffer (100mM NaCI, 0.0013M HCI at pH3.0) . The stress buffer with pepsin was prepared by adding 1.11 mg/ml pepsin (from porcine gastric mucosa, P7000, Sigma, 474U/mg) as pH3+pepsin buffer, and also was incubated with 10ul catalase. The mixture was incubated at 37℃ in thermomixer for 0, 30, 60 and 90 minutes separately. 10μl sample extracted from the mixture was added into 90μl activity buffer as stop mixture. Then 100μl stop mixture was added with 50μl 0.2%H 2O 2 solution to measure absorbance. The absorbance was measured at 240nm for 10 minutes at room temperature (interval 34sec, shake before first read) . One slop could be calculated by OD vs min, which presents the activity. The activity at pH7.0 without stress condition was set as reference, and the residual activity at stress condition (pH3.0 or pH3.0+pepsin) compared with reference was calculated as relative stability.
