Definitions

  • the present invention relates to detergent compositions comprising polypeptides having xanthan degrading activity.
  • the invention relates to such detergent compositions comprising polypeptides within the glycosyl hydrolase family 5 (GH5) having xanthan degrading activity.
  • the invention also relates to methods for producing said detergent compositions and to the use of said detergent compositions in cleaning applications.
  • Xanthan gum is a polysaccharide secreted by the bacterium Xanthomonas campestris. It is produced by the fermentation of glucose, sucrose, or lactose in an aqueous growth medium by X. campestris. After a fermentation period, the polysaccharide is precipitated from the growth medium with isopropyl alcohol, dried, and ground into a fine powder. Later, the powder is added to a liquid medium to form the gum.
  • Xanthan is composed of pentasaccharide subunits, forming a cellulose backbone with trisaccharide side chains composed of mannose-(beta1 ,4)-glucuronic-acid-(beta1 ,2)-mannose attached to alternate glucose residues in the backbone by alpha1 ,3 linkages.
  • This biopolymer is of great commercial significance because of its superior pseudoplasticity, thixotropy, and viscosity.
  • xanthan gum has been widely used as an ingredient in many consumer products including foods (e.g., as thickening agent in salat dressings and dairy products) and cosmetics (e.g., as stabilizer and thickener in toothpaste and make-up to prevent ingredients from separating) and cosmetics (e.g., sun creams).
  • foods e.g., as thickening agent in salat dressings and dairy products
  • cosmetics e.g., as stabilizer and thickener in toothpaste and make-up to prevent ingredients from separating
  • cosmetics e.g., sun creams
  • xanthan gum has found use in the oil industry where xanthan gum is used in large quantities to thicken drilling mud. These fluids serve to carry the solids cut by the drilling bit back to the surface. When the circulation stops, the solids still remain suspended in the drilling fluid. The widespread use of horizontal drilling has led to its expanded use. Xanthan gum is also added to self-consolidating concrete, including concrete poured underwater, to increase its viscosity. The widespread use of xanthan gum has led to a desire to be able to degrade solutions or gels of xanthan gum.
  • Xanthan lyases are enzymes that cleave the beta-D-mannosylalpha-beta-D-1 ,4-glucuronosyl bond of xanthan and have been described in the literature.
  • Xanthan degrading enzymes are known in the art e.g., two xanthan lyases isolated from Paenibacillus alginolyticus XL-1.

Description

DETERGENT COMPOSITIONS COMPRISING POLYPEPTIDES HAVING XANTHAN DEGRADING ACTIVITY
Reference to a Sequence Listing
This application contains a Sequence Listing in computer readable form, which is incorporated herein by reference.
Background of the invention
Field of the invention
The present invention relates to detergent compositions comprising polypeptides having xanthan degrading activity. In particular the invention relates to such detergent compositions comprising polypeptides within the glycosyl hydrolase family 5 (GH5) having xanthan degrading activity. The invention also relates to methods for producing said detergent compositions and to the use of said detergent compositions in cleaning applications.
Description of the related art
Xanthan gum is a polysaccharide secreted by the bacterium Xanthomonas campestris. It is produced by the fermentation of glucose, sucrose, or lactose in an aqueous growth medium by X. campestris. After a fermentation period, the polysaccharide is precipitated from the growth medium with isopropyl alcohol, dried, and ground into a fine powder. Later, the powder is added to a liquid medium to form the gum.
Xanthan is composed of pentasaccharide subunits, forming a cellulose backbone with trisaccharide side chains composed of mannose-(beta1 ,4)-glucuronic-acid-(beta1 ,2)-mannose attached to alternate glucose residues in the backbone by alpha1 ,3 linkages. This biopolymer is of great commercial significance because of its superior pseudoplasticity, thixotropy, and viscosity.
In recent years xanthan gum has been widely used as an ingredient in many consumer products including foods (e.g., as thickening agent in salat dressings and dairy products) and cosmetics (e.g., as stabilizer and thickener in toothpaste and make-up to prevent ingredients from separating) and cosmetics (e.g., sun creams).
In addition, xanthan gum has found use in the oil industry where xanthan gum is used in large quantities to thicken drilling mud. These fluids serve to carry the solids cut by the drilling bit back to the surface. When the circulation stops, the solids still remain suspended in the drilling fluid. The widespread use of horizontal drilling has led to its expanded use. Xanthan gum is also added to self-consolidating concrete, including concrete poured underwater, to increase its viscosity. The widespread use of xanthan gum has led to a desire to be able to degrade solutions or gels of xanthan gum. Complete enzymatic degradation of xanthan gum has till now required several enzymatic activities including xanthan lyase activity and endo-beta-1 ,4-glucanase activity. Xanthan lyases are enzymes that cleave the beta-D-mannosylalpha-beta-D-1 ,4-glucuronosyl bond of xanthan and have been described in the literature. Xanthan degrading enzymes are known in the art e.g., two xanthan lyases isolated from Paenibacillus alginolyticus XL-1.
Glycosyl hydrolases are enzymes that catalyze the hydrolysis of the glycosyl bond to release smaller sugars. There are over 100 classes of Glycosyl hydrolases which have been classified.. The glycosyl hydrolase family 5 (GH5) includes endo-glucanases (EC 3.2.1 .4), endo-beta-1 ,4-xylanase (EC 3.2.1 .8); beta-glucosidase (EC 3.2.1.21 ); beta-mannosidase (EC 3.2.1.25). However, until now identification of xanthan degrading enzymes have not been reported in glycosyl hydrolase family 5.
The mature peptide in SEQ ID NO: 2 is 45 % identical and the mature peptide in SEQ ID NO: 4 is 57 % identical to a predicted endoglucanase from the genome of Echinicola vietnamensis (UNIPROT: L0FVA9).
The mature peptide in SEQ ID NO: 6 is 47 % identical to an uncharacterized protein from the genome of Barnesiella intestinihominis (UNIPROT: K0WXE1 ).
The mature peptide in SEQ ID NO: 8 is 100 % identical to an uncharacterized protein from the genome of Pseudomonas stutzeri (UNIPROT: M2V1 S3).
Summary of the invention
The invention provides new and improved detergent compositions comprising enzymes for the degradation of xanthan gum and methods for producing said detergent compositions and to the use of said detergent compositions in cleaning applications.
The present inventors have surprisingly discovered a new group of enzymes that have xanthan degrading activity - and which do not belong to any glycosyl hydrolase family previously known to comprise this enzymatic activity. The enzymes have no significant sequence similarity to any known enzyme having xanthan degrading activity.
The present invention provides detergent compositions comprising polypeptides having xanthan degrading activity, i.e., having activity on xanthan gum and/or having activity on xanthan gum pretreated with xanthan lyase.
Accordingly, the present invention provides a detergent composition comprising polypeptide of glycosyl hydrolase family 5 having xanthan degrading activity.

(d) a variant of the mature polypeptide of any of SEQ ID NO: 2 SEQ ID NO: 4, SEQ ID NO: 6 or SEQ ID NO: 8 comprising a substitution, deletion, and/or insertion at one or more positions;

Detailed Description of the Invention
The present invention provides detergent composition comprising GH5 polypeptides having xanthan degrading activity. The polypeptides do not belong to a GH family known to comprise enzymes, which degrade xanthan. In addition, the detergent composition comprising a combination of xanthan lyase and an enzyme of the invention having xanthan degrading activity shows a synergistic improved wash performance over using a detergent composition comprising either a xanthan lyase or a GH5 polypeptide alone having xanthan degrading activity. Definitions
Coding sequence: The term "coding sequence" means a polynucleotide, which directly specifies the amino acid sequence of a polypeptide. The boundaries of the coding sequence are generally determined by an open reading frame, which begins with a start codon such as ATG, GTG, or TTG and ends with a stop codon such as TAA, TAG, or TGA. The coding sequence may be a genomic DNA, cDNA, synthetic DNA, or a combination thereof.
Colour clarification: During washing and wearing loose or broken fibers can accumulate on the surface of the fabrics. One consequence can be that the colours of the fabric appear less bright or less intense because of the surface contaminations. Removal of the loose or broken fibers from the textile will partly restore the original colours and looks of the textile. By the term "colour clarification", as used herein, is meant the partial restoration of the initial colours of textile.
Detergent Composition:
The term "detergent composition", includes unless otherwise indicated, granular or powder- form all-purpose or heavy-duty washing agents, especially cleaning detergents; liquid, gel or paste- form all-purpose washing agents, especially the so- called heavy-duty liquid (HDL) types; liquid fine- fabric detergents; hand dishwashing agents or light duty dishwashing agents, especially those of the high-foaming type; machine dishwashing agents, including the various tablet, granular, liquid and rinse-aid types for household and institutional use; liquid cleaning and disinfecting agents, including antibacterial hand-wash types, cleaning bars, soap bars, mouthwashes, denture cleaners, car or carpet shampoos, bathroom cleaners; hair shampoos and hair-rinses; shower gels, foam baths; metal cleaners; as well as cleaning auxiliaries such as bleach additives and "stain-stick" or pre-treat types. The terms "detergent composition" and "detergent formulation" are used in reference to mixtures which are intended for use in a wash medium for the cleaning of soiled objects. In some embodiments, the term is used in reference to laundering fabrics and/or garments (e.g., "laundry detergents"). In alternative embodiments, the term refers to other detergents, such as those used to clean dishes, cutlery, etc. (e.g., "dishwashing detergents"). It is not intended that the present invention be limited to any particular detergent formulation or composition. The term "detergent composition" is not intended to be limited to compositions that contain surfactants. It is intended that in addition to the variants according to the invention, the term encompasses detergents that may contain, e.g., surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, fabric conditioners, foam boosters, suds suppressors, dyes, perfume, tannish inhibitors, optical brighteners, bactericides, fungicides, soil suspending agents, anticorrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.
Dish wash: The term "dish wash" refers to all forms of washing dishes, e.g., by hand or automatic dish wash. Washing dishes includes, but is not limited to, the cleaning of all forms of crockery such as plates, cups, glasses, bowls, all forms of cutlery such as spoons, knives, forks and serving utensils as well as ceramics, plastics, metals, china, glass and acrylics. Dish washing composition: The term "dish washing composition" refers to all forms of compositions for cleaning hard surfaces. The present invention is not restricted to any particular type of dish wash composition or any particular detergent.
Enzyme Detergency benefit: The term "enzyme detergency benefit" is defined herein as the advantageous effect an enzyme may add to a detergent compared to the same detergent without the enzyme. Important detergency benefits which can be provided by enzymes are stain removal with no or very little visible soils after washing and or cleaning, prevention or reduction of redeposition of soils released in the washing process an effect that also is termed anti-redeposition, restoring fully or partly the whiteness of textiles, which originally were white but after repeated use and wash have obtained a greyish or yellowish appearance an effect that also is termed whitening. Textile care benefits, which are not directly related to catalytic stain removal or prevention of redeposition of soils are also important for enzyme detergency benefits. Examples of such textile care benefits are prevention or reduction of dye transfer from one fabric to another fabric or another part of the same fabric an effect that is also termed dye transfer inhibition or anti-backstaining, removal of protruding or broken fibers from a fabric surface to decrease pilling tendencies or remove already existing pills or fuzz an effect that also is termed anti-pilling, improvement of the fabric-softness, colour clarification of the fabric and removal of particulate soils which are trapped in the fibers of the fabric or garment. Enzymatic bleaching is a further enzyme detergency benefit where the catalytic activity generally is used to catalyze the formation of bleaching component such as hydrogen peroxide or other peroxides.
Fragment: The term "fragment" means a polypeptide having one or more (e.g. , several) amino acids absent from the amino and/or carboxyl terminus of a mature polypeptide or domain; wherein the fragment has xanthan degrading activity.
Hard surface cleaning: The term "Hard surface cleaning" is defined herein as cleaning of hard surfaces wherein hard surfaces may include floors, tables, walls, roofs etc. as well as surfaces of hard objects such as cars (car wash) and dishes (dish wash). Dish washing includes but are not limited to cleaning of plates, cups, glasses, bowls, and cutlery such as spoons, knives, forks, serving utensils, ceramics, plastics, metals, china, glass and acrylics.
Improved wash performance: The term "improved wash performance" is defined herein as a (variant) enzyme (also a blend of enzymes, not necessarily only variants but also backbones, and in combination with certain cleaning composition etc.) displaying an alteration of the wash performance of a protease variant relative to the wash performance of the parent protease variant e.g. by increased stain removal. The term "wash performance" includes wash performance in laundry but also e.g. in dish wash.
Isolated: The term "isolated" means a substance in a form or environment that does not occur in nature. Non-limiting examples of isolated substances include (1 ) any non-naturally occurring substance, (2) any substance including, but not limited to, any enzyme, variant, nucleic acid, protein, peptide or cofactor, that is at least partially removed from one or more or all of the naturally occurring constituents with which it is associated in nature; (3) any substance modified by the hand of man relative to that substance found in nature; or (4) any substance modified by increasing the amount of the substance relative to other components with which it is naturally associated (e.g. , recombinant production in a host cell; multiple copies of a gene encoding the substance; and use of a stronger promoter than the promoter naturally associated with the gene encoding the substance). An isolated substance may be present in a fermentation broth sample; e.g. a host cell may be genetically modified to express the polypeptide of the invention. The fermentation broth from that host cell will comprise the isolated polypeptide.
Mature polypeptide: The term "mature polypeptide" means a polypeptide in its final form following translation and any post-translational modifications, such as N-terminal processing, C-terminal truncation, glycosylation, phosphorylation, etc. In one aspect, the mature polypeptide is amino acids 1 to 802 of SEQ ID NO: 2. In a second aspect, the mature polypeptide is amino acids 1 to 808 of SEQ ID NO: 4. In a third aspect, the mature polypeptide is amino acids 1 to 800 of SEQ ID NO: 6. In a fourth aspect, the mature polypeptide is amino acids 1 to 657 of SEQ ID NO: 8. It is known in the art that a host cell may produce a mixture of two of more different mature polypeptides (i.e., with a different C-terminal and/or N-terminal amino acid) expressed by the same polynucleotide. It is also known in the art that different host cells process polypeptides differently, and thus, one host cell expressing a polynucleotide may produce a different mature polypeptide (e.g., having a different C-terminal and/or N-terminal amino acid) as compared to another host cell expressing the same polynucleotide.
Mature polypeptide coding sequence: The term "mature polypeptide coding sequence" means a polynucleotide that encodes a mature polypeptide having xanthan degrading activity. In one aspect, the mature polypeptide coding sequence is nucleotides 109 to 2514 of SEQ ID NO: 1. Nucleotides 1 to 108 of SEQ ID NO: 1 encode a signal peptide. In one aspect, the mature polypeptide coding sequence is nucleotides 1 12 to 2493 of SEQ ID NO: 3. Nucleotides 1 to 1 1 1 of SEQ ID NO: 3 encode a signal peptide. In one aspect, the mature polypeptide coding sequence is nucleotides 106 to 2505 of SEQ ID NO: 5. Nucleotides 1 to 105 of SEQ ID NO: 5 encode a signal peptide. In one aspect, the mature polypeptide coding sequence is nucleotides 109 to 2079 of SEQ ID NO: 7. Nucleotides 1 to 108 of SEQ ID NO: 7 encode a signal peptide.
Nucleic acid construct: The term "nucleic acid construct" means a nucleic acid molecule, either single- or double-stranded, which is isolated from a naturally occurring gene or is modified to contain segments of nucleic acids in a manner that would not otherwise exist in nature or which is synthetic, which comprises one or more control sequences.
Operably linked: The term "operably linked" means a configuration in which a control sequence is placed at an appropriate position relative to the coding sequence of a polynucleotide such that the control sequence directs expression of the coding sequence.
Sequence identity: The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter "sequence identity".
For purposes of the present invention, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice ef a/., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled "longest identity" (obtained using the -nobrief option) is used as the percent identity and is calculated as follows:
(Identical Residues x 100)/(Length of Alignment - Total Number of Gaps in Alignment) For purposes of the present invention, the sequence identity between two deoxyribonucleotide sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, supra) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice ef a/. , 2000, supra), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EDNAFULL (EMBOSS version of NCBI NUC4.4) substitution matrix. The output of Needle labeled "longest identity" (obtained using the -nobrief option) is used as the percent identity and is calculated as follows:
(Identical Deoxyribonucleotides x 100)/(Length of Alignment - Total Number of Gaps in Alignment)
Textile: The term "textile" means any textile material including yarns, yarn intermediates, fibers, non-woven materials, natural materials, synthetic materials, and any other textile material, fabrics made of these materials and products made from fabrics (e.g., garments and other articles). The textile or fabric may be in the form of knits, wovens, denims, non-wovens, felts, yarns, and towelling. The textile may be cellulose based such as natural cellulosics, including cotton, flax/linen, jute, ramie, sisal or coir or manmade cellulosics (e.g. originating from wood pulp) including viscose/ rayon, ramie, cellulose acetate fibers (tricell), lyocell or blends thereof. The textile or fabric may also be non-cellulose based such as natural polyamides including wool, camel, cashmere, mohair, rabit and silk or synthetic polymer such as nylon, aramid, polyester, acrylic, polypropylen and spandex/elastane, or blends thereof as well as blend of cellulose based and non-cellulose based fibers. Examples of blends are blends of cotton and/or rayon/viscose with one or more companion material such as wool, synthetic fibers (e.g. polyamide fibers, acrylic fibers, polyester fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyurethane fibers, polyurea fibers, aramid fibers), and cellulose-containing fibers (e.g. rayon/viscose, ramie, flax/linen, jute, cellulose acetate fibers, lyocell). Fabric may be conventional washable laundry, for example stained household laundry. When the term fabric or garment is used it is intended to include the broader term textiles as well.
Textile care benefit: "Textile care benefits", which are not directly related to catalytic stain removal or prevention of redeposition of soils, are also important for enzyme detergency benefits. Examples of such textile care benefits are prevention or reduction of dye transfer from one textile to another textile or another part of the same textile an effect that is also termed dye transfer inhibition or anti-backstaining, removal of protruding or broken fibers from a textile surface to decrease pilling tendencies or remove already existing pills or fuzz an effect that also is termed anti-pilling, improvement of the textile-softness, colour clarification of the textile and removal of particulate soils which are trapped in the fibers of the textile. Enzymatic bleaching is a further enzyme detergency benefit where the catalytic activity generally is used to catalyze the formation of bleaching component such as hydrogen peroxide or other peroxides or other bleaching species.
Wash performance: The term "wash performance" is used as an enzyme's ability to remove stains present on the object to be cleaned during e.g. wash or hard surface cleaning. The improvement in the wash performance may be quantified by calculating the so-called intensity value (Int) as defined in 'Automatic Mechanical Stress Assay (AMSA) for laundry' herein. See also the wash performance test in Example 18 herein.
Whiteness: The term "Whiteness" is defined herein as a broad term with different meanings in different regions and for different customers. Loss of whiteness can e.g. be due to greying, yellowing, or removal of optical brighteners/hueing agents. Greying and yellowing can be due to soil redeposition, body soils, colouring from e.g. iron and copper ions or dye transfer. Whiteness might include one or several issues from the list below: colorant or dye effects; incomplete stain removal (e.g. body soils, sebum ect.); re-deposition (greying, yellowing or other discolorations of the object) (removed soils re-associates with other part of textile, soiled or unsoiled); chemical changes in textile during application; and clarification or brightening of colours.
Xanthan Lyase: The term "xanthan lyase" is defined herein as an enzyme that cleaves the beta-D-mannosyl-beta-D-1 ,4-glucuronosyl bonds in xanthan gum (EC 4.2.2.12). For purposes of the present invention, xanthan lyase activity is determined according to the procedure described in the Examples in the 'Xanthan lyase activity assay.
Xanthan degrading activity: The term "xanthan degrading activity" is defined herein as ability to cause viscosity reduction of a xanthan solution. Xanthan solution is highly viscous even at low polymer concentrations, and this viscosity is associated with the polymer degree of xanthan. Therefore, viscosity reduction can be used to monitor xanthan degradation. The viscosity reduction may be detected using the viscosity pressure assay described in Example 6.
Xanthan degrading activity includes activity towards intact xanthan as well as activity towards xanthan pretreated with xanthan lyase (modified xanthan gum - see Example 8).
Activity on xanthan gum: The term "GH5 polypeptide having activity on xanthan gum" or a "polypeptide having activity on xanthan gum and belonging to the GH5 class of glycosyl hydrolases" is defined as a polypeptide comprising a domain belonging to the GH5 class of glycosyl hydrolases, and having significant activity on xanthan gum. In one aspect of the invention a GH5 polypeptide having activity on xanthan gum may be a polypeptide having a sequence selected among SEQ ID NO: 2, SEQ ID NO: 4, SEQ ID NO: 6, and SEQ ID NO: 8.
Activity on xanthan gum pretreated with xanthan lyase: The term "GH5 polypeptide having activity on xanthan gum pretreated with xanthan lyase" or a "polypeptide having activity on xanthan gum pretreated with xanthan lyase and belonging to the GH5 class of glycosyl hydrolases" is defined as a polypeptide comprising a domain belonging to the GH5 class of glycosyl hydrolases, and having significant activity on xanthan gum pretreated with xanthan lyase (modified xanthan gum - see Example 8). In one aspect of the invention a GH5 polypeptide having activity on xanthan gum pretreated with xanthan lyase may be a polypeptide having a sequence selected among SEQ ID NO: 2, SEQ ID NO: 4, SEQ ID NO: 6, and SEQ ID NO: 8.
Detergent compositions comprising Polypeptides having xanthan degrading activity

Hydrotropes
A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions (or oppositely, polar substances in a non-polar environment). Typically, hydrotropes have both hydrophilic and a hydrophobic character (so-called amphiphilic properties as known from surfactants); however the molecular structure of hydrotropes generally do not favor spontaneous self-aggregation, see e.g. review by Hodgdon and Kaler (2007), Current Opinion in Colloid & Interface Science 12: 121 -128. Hydrotropes do not display a critical concentration above which self- aggregation occurs as found for surfactants and lipids forming miceller, lamellar or other well defined meso-phases. Instead, many hydrotropes show a continuous-type aggregation process where the sizes of aggregates grow as concentration increases. However, many hydrotropes alter the phase behavior, stability, and colloidal properties of systems containing substances of polar and non-polar character, including mixtures of water, oil, surfactants, and polymers. Hydrotropes are classically used across industries from pharma, personal care, food, to technical applications. Use of hydrotropes in detergent compositions allow for example more concentrated formulations of surfactants (as in the process of compacting liquid detergents by removing water) without inducing undesired phenomena such as phase separation or high viscosity.
The detergent may contain 0-10% by weight, for example 0-5% by weight, such as about 0.5 to about 5%, or about 3% to about 5%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized.

In a dish wash detergent, the level of builder is typically 40-65%, particularly 50-65%. The builder and/or co-builder may particularly be a chelating agent that forms water-soluble complexes with Ca and Mg. Any builder and/or co-builder known in the art for use in detergents may be utilized. Non-limiting examples of builders include zeolites, diphosphates (pyrophosphates), triphosphates such as sodium triphosphate (STP or STPP), carbonates such as sodium carbonate, soluble silicates such as sodium metasilicate, layered silicates (e.g., SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA), diethanolamine (DEA, also known as 2,2'-iminodiethan-1-ol), triethanolamine (TEA, also known as 2,2',2"-nitrilotriethan-1-ol), and (carboxymethyl)inulin (CMI), and combinations thereof.

Formulation of detergent products
The detergent composition of the invention may be in any convenient form, e.g., a bar, a homogenous tablet, a tablet having two or more layers, a pouch having one or more compartments, a regular or compact powder, a granule, a paste, a gel, or a regular, compact or concentrated liquid.
Pouches can be configured as single or multicompartments. It can be of any form, shape and material which is suitable for hold the composition, e.g. without allowing the release of the composition to release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch.

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches or in different layers of tablets. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.
A liquid or gel detergent , which is not unit dosed, may be aqueous, typically containing at least 20% by weight and up to 95% water, such as up to about 70% water, up to about 65% water, up to about 55% water, up to about 45% water, up to about 35% water. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid or gel. An aqueous liquid or gel detergent may contain from 0-30% organic solvent.
A liquid or gel detergent may be non-aqueous.
Laundry soap bars
The enzymes of the invention may be added to laundry soap bars and used for hand washing laundry, fabrics and/or textiles. The term laundry soap bar includes laundry bars, soap bars, combo bars, syndet bars and detergent bars. The types of bar usually differ in the type of surfactant they contain, and the term laundry soap bar includes those containing soaps from fatty acids and/or synthetic soaps. The laundry soap bar has a physical form which is solid and not a liquid, gel or a powder at room temperature. The term solid is defined as a physical form which does not significantly change over time, i.e. if a solid object (e.g. laundry soap bar) is placed inside a container, the solid object does not change to fill the container it is placed in. The bar is a solid typically in bar form but can be in other solid shapes such as round or oval.
The laundry soap bar may contain one or more additional enzymes, protease inhibitors such as peptide aldehydes (or hydrosulfite adduct or hemiacetal adduct), boric acid, borate, borax and/or phenylboronic acid derivatives such as 4-formylphenylboronic acid, one or more soaps or synthetic surfactants, polyols such as glycerine, pH controlling compounds such as fatty acids, citric acid, acetic acid and/or formic acid, and/or a salt of a monovalent cation and an organic anion wherein the monovalent cation may be for example Na+, K+ or NhV and the organic anion may be for example formate, acetate, citrate or lactate such that the salt of a monovalent cation and an organic anion may be, for example, sodium formate.
The laundry soap bar may also contain complexing agents like EDTA and HEDP, perfumes and/or different type of fillers, surfactants e.g. anionic synthetic surfactants, builders, polymeric soil release agents, detergent chelators, stabilizing agents, fillers, dyes, colorants, dye transfer inhibitors, alkoxylated polycarbonates, suds suppressers, structurants, binders, leaching agents, bleaching activators, clay soil removal agents, anti-redeposition agents, polymeric dispersing agents, brighteners, fabric softeners, perfumes and/or other compounds known in the art.

The invention is not limited to preparing the laundry soap bars by any single method. The premix of the invention may be added to the soap at different stages of the process. For example, the premix containing a soap, the enzyme of the invention, optionally one or more additional enzymes, a protease inhibitor, and a salt of a monovalent cation and an organic anion may be prepared and and the mixture is then plodded. The enzyme of the invention and optional additional enzymes may be added at the same time as the protease inhibitor for example in liquid form. Besides the mixing step and the plodding step, the process may further comprise the steps of milling, extruding, cutting, stamping, cooling and/or wrapping.
Formulation of enzyme in co-granule
The enzyme comprised in the detergent compositions of the invention may be formulated as a granule for example as a co-granule that combines one or more enzymes. Each enzyme will then be present in more granules securing a more uniform distribution of enzymes in the detergent. This also reduces the physical segregation of different enzymes due to different particle sizes. Methods for producing multi-enzyme co-granulates for the detergent industry are disclosed in the IP.com disclosure IPCOM000200739D.
Another example of formulation of enzymes by the use of co-granulates are disclosed in WO 2013/188331 , which relates to a detergent composition comprising (a) a multi-enzyme co- granule; (b) less than 10 wt zeolite (anhydrous basis); and (c) less than 10 wt phosphate salt (anhydrous basis), wherein said enzyme co-granule comprises from 10 to 98 wt% moisture sink component and the composition additionally comprises from 20 to 80 wt% detergent moisture sink component.

Examples
Activity assays
Xanthan lyase activity assay
0.8 mL 100 mM HEPES buffer, pH 6.0 was mixed with 0.2 mL Xanthan gum (5 mg/mL) dissolved in water in a 1 mL 1 cm cuvette. The cuvette was inserted into a spectrophotometer (Agilent G1 103A 8453A, CA, USA) with temperature control set at 40 °C. The solution was pre-incubated for 10 min and 0.1 mL sample was added and the solution was mixed by aspiring and dispensing the solution for at least 5 times using a pipette. Total reaction volume was 1 .1 mL. Absorbance at 235 nm was collected for 10 min using a 30 sec measuring interval. Initial activity was calculated by using the software (UV-Visible Chemstation Rev A.10.01 [81], Agilent).
Example 1 : Strain and DNA
The DNA in SEQ ID NO: 1 encoding the GH5 polypeptide EXa of SEQ ID NO: 2 was obtained from an Opitutaceae species isolated from an environmental soil sample collected in Denmark.
The DNA SEQ ID NO: 3 encoding the GH5 polypeptide EXb of SEQ ID NO: 4 was isolated from an environmental sample collected in Denmark.
The DNA SEQ ID NO: 5 encoding the GH5 polypeptide EXc of SEQ ID NO: 5 was isolated from an environmental sample collected in Denmark.
The DNA SEQ ID NO: 7 encoding the GH5 polypeptide EXd of SEQ ID NO: 8 was obtained from the public database (UNIPROT M2V1 S3) but originates from a strain of Pseudomonas stutzeri collected from a Galapagos Rift hydrothermal vent, Ecuador.
Codon optimized synthetic DNA encoding the mature peptide sequences of the four polypeptides were prepared (SEQ ID NO: 9; SEQ ID NO: 10, SEQ ID NO: 1 1 ; SEQ ID NO: 12).
Example 2: Cloning and expression of GH5 polypeptides
The GH5 encoding genes were either cloned by conventional techniques from the strains indicated above or from the synthetic DNA and inserted into a suitable plasmid as described below.
Example 2a: Cloning and expression of GH5 polypeptides in E.coli
The mature peptide encoding part of the GH5 endo-glucanase genes, SEQ ID NO: 1 , 3, 5 and 7 was inserted with an N-terminal poly histidine tag with an extra proline and arginine (HHHHHHPR) (SEQ ID NO: 19) after the methionine in the E.coli pET-32a(+) vector from Novagen with standard recombinant techniques. The expression plasmid containing the insert was purified from an E. coli transformant harboring the plasmid and transformed into E.coli Xjb (DE3) host cells (from Zymo Research). A fresh clone of E.coli Xjb (DE3) containing the pET32-GH5 vector, was grown overnight in Terrific Broth containing 100 ug/ml ampicillin. Next day, a fresh 500 ml culture was inoculated with 1 ml overnight culture and cells were cultured (37 °C, 250 rpm) to an optical density (OD600) between 6-8. Protein expression was induced by 1 mM isopropylthio-D- galactosidase (IPTG) and 6 mM arabinose for 4.5 hours at 20 °C. After continued culture, cells were harvested by centrifugation and lysed by Bugbuster® (Novagen). The soluble fraction was used for polyhistidine tag purification of the GH5 polypeptides SEQ ID NO: 13, 14 and 15 as described in example 4.
Example 2b: Cloning and expression of GH5 polypeptides in Bacillus subtilis The synthetic codon optimized genes SEQ ID NO: 10, 1 1 and 12 were cloned into the Bacillus expression vector described in WO 2012/025577. The genes were expressed by replacing the native secretion signal sequence with the Bacillus clausii secretion signal MKKPLGKIVASTALLISVAFSSSIASA (SEQ ID NO: 20) with an extra affinity tag sequence (HHHHHHPR) (SEQ ID NO: 19) at the C-terminal of the signal peptide, to facilitate the purification process. This resulted in a recombinant mature polypeptide with a His tag at the front of the N- terminal of the mature wild type sequence (SEQ ID NO: 16, 17 and 18).
One clone with the correct recombinant gene sequence was selected and the corresponding plasmid was integrated by homologous recombination into the Bacillus subtilis host cell genome (pectate lyase locus) and the gene construct was expressed under the control of a triple promoter system as described in W099/43835. The gene coding for chloramphenicol acetyltransferase was used as a marker (as described in Diderichsen ef a/. , 1993, Plasmid 30:312- 315).
Chloramphenicol resistant transformants were analyzed by PCR to verify the correct size of the amplified fragment. A recombinant B. subtilis clone containing the integrated expression construct was selected and cultivated on a rotary shaking table in 500 mL baffled Erlenmeyer flasks each containing 100 ml yeast extract-based media. The clone was cultivated for 5 days at 30°C. The enzyme containing supernatants were harvested and the enzyme purified as described in Example 5.
Example 3: Purification of wild type GH5 polypeptide from the natural Opitutaceae strain
The Opitutaceae strain was cultivated on a rotary shaking table in 500 mL baffled Erlenmeyer flasks each containing 100 ml mineral solution with 0.5% xanthan gum. The strain was cultivated for 20 days at 30°C. A total of 2.0 L supernatant was harvested by centrifugation and was filtered using a 0.2 μιη bottle top filter (Nalgene Nunc). The broth was concentrated to 300 mL using ultra-filtration (Sartorius) with 30 kDa cut-off. Equal volume of 3.2 M ammonium sulphate in 40 mM Tris-HCI, pH 7.9 was slowly added with continuous stirring. The sample was filtered using Whatman glass filters (1.7 μιη - 0.7 μιη) to remove larger particles. The sample was applied on a 20 mL Phenyl- sepharose high performance column (GE Healthcare) pre-equilibrated with 1.6 M ammonium sulphate in 20 mM Tris-HCI, pH 7.9 (equilibration buffer). Unbound protein was eluted by two column volumes of equilibration buffer. Elution was done by a 12 column volume linear gradient from 1.6 M to 0.0 M ammonium sulphate in 20 mM Tris-HCI, pH 7.9. A last elution step of 4 column volume with equilibration buffer was used to elute tightly bound protein. The absorbance at 280 nm was recorded during the entire purification. Protein containing fractions identified by the absorbance at 280 nm in the chromatogram were analyzed by SDS-PAGE (NuPAGE, Invitrogen). Fractions judged as pure were pooled. The sample was concentration from 30 to 4 mL using Macrosep ultra filtration device with 3 kDa cut-off (Pall). The protein concentration was determined by measuring the absorbance at 280 nm using the calculated extinction coefficient where 1 mg/mL equaled 1 .89 absorbance units.
Example 4: Purification of recombinant GH5 polypeptide produced in E.coli
200 mL lysed cells (grown as example 2a) were filtered through Fast PES 0.2 μιη bottle- top filters to remove debris and unbroken cells. 200 mL of equilibration buffer (20 mM Tris-HCI, pH 7.5 + 500 mM NaCI) was added to the crude protein solution. A 20 mL HisPrep column loaded with Ni2+ was equilibrated with equilibration buffer until a stable UV baseline was obtained. The absorbance at 280 nm was continuously monitored throughout the purification. Crude protein was loaded on the column using a flow rate of 4 mL/min. Unbound protein was removed by washing the column with equilibration buffer until a stable UV baseline was obtained. Elution was carried out by a two-step linear gradient using 20 mM Tris-HCI, pH 7.5 + 500 mM NaCI + 500 mM Imidazole (elution buffer). First elution gradient was 10 column volumes 0 to 40 % elution buffer followed by 4 column volumes from 40% to 100 %. Peaks absorbing at 280 nm were analyzed by SDS-PAGE (NuPAGE, Invitrogen). Fractions containing protein with the correct apparent molecular weight were pooled. The pool was desalted and buffer exchanged using a Sephadex G-25 super fine desalting column equilibrated with 20 mM Tris-HCI, pH 8.0. The pool was applied on a 20 mL Source15Q column pre- equillibrated with 20 mM Tris-HCI, pH 8.0. Unbound protein was washed out using 20 mM Tris-HCI, pH 8.0 until a stable UV baseline was obtained. Elution was done by a 10 column volume linear NaCI gradient from 0 to 500 mM NaCI in 20 mM Tris-HCI, pH 8.0. Protein containing fractions were analyzed by SDS-PAGE and fractions judged as pure were pooled. Protein concentration was measured using absorbance at 280 nm using a calculated extinction coefficient where 1 mg/mL corresponded to 1.86 absorbance units.
Example 5: Purification of recombinant GH5 polypeptide produced in B. subtilis
All His-tagged enzymes were purified by immobilized metal chromatography (IMAC) using Ni2+ as the metal ion on 5 mL HisTrap Excel columns (GE Healthcare Life Sciences). The purification was done at pH 8 and the bound proteins were eluted with imidazole. The purity of the purified enzymes was checked by SDS-PAGE and the concentration of each enzyme determined by Abs 280 nm after a buffer exchange.

Example 8: Xanthan degrading activity of GH5 polypeptide and xanthan lyase on xanthan gum by measurement of viscosity reduction
The viscosity measurements were performed using the viscosity pressure assay described in WO201 1/107472. 150 μί of each 1 mL hydrolysis or control was the sample size. Results presented are the average of four measurements and are shown in table 8 and 9 below.
Modified xanthan gum was prepared by an adaption of Nankai et al. 1999. "Microbial system for polysaccharide depolymerization: enzymatic route for xanthan depolymerization by Bacillus sp strain GL1." Applied and Environmental Microbiology 65(6): 2520-2526.
2.5 g of xanthan gum (CP Kelco) was wetted with 5 mL of 96 % ethanol in a 2 L beaker. 500 mL of 100 mM ACES buffer pH 7.00 was added and the solution stirred at ambient temperature for 2 h. 250 [it of xanthan lyase (Bacillus sp., Megazyme) was added and the solution incubated for 20 h at 50 °C. The sample was then cooled by placing the beaker on ice. After hydrolysis was 1400 mL of ice cold 96 % ethanol was added to the 500 mL sample, under stirring. Precipitation occurs, and after approximately 5 min the ethanol was decanted removing the pyruvated mannose residues. The sample was vacuum filtered and transferred to a glass plate. The glasses were dried at 50 °C for 20 h. The sample was collected, weighed, and grinded. The hydrolysis conditions were as follows: 40 °C, 0.35 % xanthan gum (XG) in 50 mM HEPES buffer + 0.01 % triton X-100 pH 7.0. The modified xanthan gum powder (mXG) was prepared as described above and a 0.7 % solution was prepared using the same procedure as outlined for XG. Enzyme was added upon thermal equilibration. The initial viscosity is measured prior to enzyme addition, after thermal equilibration. Controls are the same with buffer added instead of enzyme. Buffer was monitored to determine the ultimate end point of a total hydrolysis.

Example 9: Wash performance of GH5 polypeptide and xanthan lyase
The wash performance of the GH5 enzyme was assessed in laundry wash experiments using a Mini wash assay, which is a test method where soiled textile is continuously lifted up and down into the test solution and subsequently rinsed. The wash experiment was conducted under the experimental conditions specified in Table 10.
The textiles were subsequently air-dried and the wash performance was measured as the brightness of the color of the textiles. Brightness can be expressed as the Remission (R), which is a measure for the light reflected or emitted from the test material when illuminated with white light. The Remission (R) of the textiles was measured at 460 nm using a Zeiss MCS 521 VIS spectrophotometer. The measurements were done according to the manufacturer's protocol.
The performance of the new enzyme (combination) was compared to the performance of detergent alone (blank). An enzyme (combination) is considered to exhibit improved wash performance, if it performs better than the detergent alone (i.e. RENZYME > RBLANK) (see Table 13 and 14).

The wash performance of variants in liquid and powder detergents was determined by using the following standardized stains, all obtainable from CFT (Center for Testmaterials) B.V., Vlaardingen, Netherlands:
A: Fluid make-up: product no. PCS17
B: Fluid make-up: product no. CS17
For the tests in liquid detergents, a liquid washing agent with the following composition was used as base formulation (all values in weight percent): 0 to 0.5% xanthan gum, 0.2 to 0.4% antifoaming agent, 6 to 7% glycerol, 0.3 to 0.5% ethanol, 0 to 7% FAEOS (fatty alcohol ether sulfate), 10 to 28% nonionic surfactants, 0.5-1 % boric acid, 1 to 2% sodium citrate (dihydrate), 2 to 4% soda, O to 16% coconut fatty acid, 0.5% HEDP (1-hydroxyethane-(1 , 1-diphosphonic acid)), 0 to 0.4% PVP (polyvinylpyrrolidone), 0 to 0.05% optical brighteners, 0 to 0.001 % dye, remainder deionized water.
Based on this base formulation, detergent was prepared by adding the respective enzyme combination as indicated in table 15. As a reference, the detergent composition without addition of the enzyme combinations was used.
The dosing ratio of the liquid washing agent was 4.7 grams per liter of washing liquor and the washing procedure was performed for 60 minutes at a temperature of 40°C, the water having a water hardness between 15.5 and 16.5° (German degrees of hardness).
For the tests in solid detergents, a European premium detergent was used as base formulation.
The whiteness, i.e. the brightening of the stains, was determined photometrically as an indication of wash performance. A Minolta CM508d spectrometer device was used, which was calibrated beforehand using a white standard provided with the unit.
The results obtained are the difference values between the remission units obtained with the detergents and the remission units obtained with the detergent containing the enzyme combinations. A positive value therefore indicates an improved wash performance due to the enzyme combinations present in the detergent. It is evident from table 15 that enzyme combinations according to the invention show improved wash performance. Table 15: Wash performance in liquid detergent

Example 11 : Wash performance of GH5 polypeptides with and without Xanthan Lyase
In this example wash performance of GH5 polypeptides was evaluated in a liquid model detergent A washed in the Automatic Mechanical Stress Assay (AMSA) at 20°C or 40°C. The wash performance of the enzymes was evaluated either alone or in combination with a Xanthan Lyase. The wash conditions used are specified in Table 17 below.
Table 17. Wash conditions used in the example 1 1 :
Figure imgf000044_0003
The enzyme and wash liquid were dosed into the AMSA plate and washed according to conditions listed in Table 17. After wash the fabric was flushed in tap water and air-dried. The performance of the enzyme was subsequently measured as the brightness of the colour of the textile samples. Brightness was measured as the intensity of the light reflected from the textile sample when illuminated with white light. Intensity was measured with a professional flatbed scanner EPSON EXPRESSION 10000XL with special designed software that extracted the intensity value from the scanned imagine through standard vector calculations.
The performance of the enzyme (or combination of enzymes) was compared to the performance of detergent alone (blank) or detergent with the Xanthan lyase (XL). An enzyme (or combination of enzymes) was considered to exhibit improved wash performance if it performed better than the detergent alone (i.e., RENZYME > RBLANK) (see Tables 18, 19, 20 and 21 ).
