Cleaning Compositions comprising Enzymes

Reference to a Sequence Listing

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 cleaning (detergent) compositions comprising an enzyme having deoxyribonuclease (DNase) activity and an enzyme having hexosaminidase activity, a method for laundering a textile and the use of an enzyme having DNase activity together with an enzyme having hexosaminidase activity. The invention further relates to use of cleaning compositions comprising an enzyme having deoxyribonuclease (DNase) activity and an enzyme having hexosaminidase activity in cleaning processes. Background of Invention

Some bacteria are capable of adhering to textiles (clothing) and forming a biofilm on the textile. Biofilm may be present on laundry items, such as fabrics, hard surfaces, such as dish wash utensils, dish washers and washing machines where they may cause malodor, which is difficult to remove even after wash. Biofilm may also make laundry items sticky and soil adheres to the sticky areas. Further, when very dirty laundry items are washed together with less dirty laundry items the dirt present in the wash liquor tend to stick to the biofilm.

Enzymes comprising hexosaminidase activity include chitinase and the use of such enzymes is described in WO9850512 (Proctor and Gamble). Enzymes having hexosaminidase activity include Dispersins such as Dispersin B (DspB), which as described is β-Ν- acetylglucosamininidases belonging to the Glycoside Hydrolase 20 family. WO04061 1 17 A2 (Kane Biotech INC) describe compositions comprising DspB for reducing and preventing biofilm caused by poly-N-acetylglucosamine-producing bacteria and describes the use of the compositions comprising DspB for reduction/ removing biofilm on medical devices and for wound care.

WO 2015/155350 (Novozymes A S) discloses the use of a polypeptide having DNase activity for preventing, reducing or removing a biofilm component e.g. DNA from an item, wherein the polypeptide is obtained from a fungal source, such as A. oryzae and the item is a textile.

Summary of the Invention

The present invention relates to a composition comprising an enzyme having DNase activity, an enzyme having hexosaminidase activity and an adjunct ingredient, wherein the hexosaminidase is selected from the group consisting of the DspB clade, the Curtobacterium clade and the Terribacillus clade. The invention further relates to the use of a such composition for deep cleaning of an item, wherein the item is a hard surface or a textile.

The invention further relates to a method for laundering an item comprising the steps of:

a. Exposing an item to a wash liquor comprising (i) an enzyme having DNase activity and an enzyme having hexosaminidase activity or (ii) a composition according to any of claims 1 -18;

b. Completing at least one wash cycle; and

c. Optionally rinsing the item,

wherein the item is a textile.

The invention further relates to the use of a combination of an enzyme having DNase activity and an enzyme having hexosaminidase activity for deep cleaning an item, wherein the item is a textile or a hard surface.

Definitions

DNase (deoxyribonuclease): The term "DNase" means a polypeptide or an enzyme with DNase activity that catalyzes the hydrolytic cleavage of phosphodiester linkages in the DNA backbone, thus degrading DNA. For purposes of the present invention, DNase activity is determined according to the procedure described in the Assay II or Assay I la. In one aspect, the DNase according to the present invention have at least 20%, e.g., at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% of the DNase activity of the mature polypeptide of SEQ ID NO: 2. In one aspect the DNase of the present invention has at least 60%, 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 100% sequence identity to the amino acid sequence having SEQ ID NO: 2.

Dispersin: The term "dispersin" and the abbreviation "Dsp" means a polypeptide having hexosaminidase activity, EC 3.2.1.- that catalyzes the hydrolysis of β-1 ,6-glycosidic linkages of N- acetyl-glucosamine polymers (poly-N-acetylglucosamine) found e.g. in biofilm. Hexosaminidase: The term "hexosaminidases" means a polypeptide having hexosaminidase activity (hexosaminidases), and includes EC 3.2.1. e.g. that catalyzes the hydrolysis of N-acetyl-D- hexosamine or N-acetyl-glucosamine polymers found e.g. in biofilm. The term includes dispersins and includes polypeptides having N-acetylglucosaminidase activity and β-Ν-acetylglucosamininidase activity. The term "polypeptide having hexosaminidase activity" may be used interchangeably with the term hexosaminidases and similar the term "polypeptide having β-Ν-acetylglucosaminidase activity" may be used interchangeably with the term β-Ν-acetylglucosamininidases. For purposes of the present invention, hexosaminidase activity is determined according to the procedure described in Assay I. In one aspect, the polypeptides of the present invention have at least 20%, e.g., at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 100% of the hexosaminidase activity of the mature polypeptide of SEQ ID NO: 14.

Biofilm: A biofilm may be produced by any group of microorganisms in which cells stick to each other or stick to a surface, such as a textile, dishware or hard surface or another kind of surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium. Bacteria living in a biofilm usually have significantly different properties from planktonic bacteria of the same species, as the dense and protected environment of the film allows them to cooperate and interact in various ways. One benefit of this environment for the microorganisms is increased resistance to detergents and antibiotics, as the dense extracellular matrix and the outer layer of cells protect the interior of the community. On laundry and hard surfaces biofilm producing bacteria can be found among the following species; Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp. On hard surfaces biofilm producing bacteria may include but are not limited to the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, Staphylococcus aureus and Stenotrophomonas sp. A wide range of bacterial and fungal microorganisms have been found to produce PNAG or PNAG-like surface polysaccharides, including but not limited to Bacillus subtillis, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas fluorescens, Yersinia pestis, Aggregatibacter actinomycetemcomitans, Streptococcus pyogenes, Streptococcus dysgalactiae (group C strep), Enterococcus faecalis, Listeria monocytogenes, Clostridium difficile, Mycobacterium tuberculosis, Mycobacterium smegmatis; Neisseria meningitides, Neisseria gonorrhea, nontypable Haemophilus influenzae, Haemophilus ducreyi, Helicobacter pylori, Campylobacter jejuni; Citrobacter rodentium, Salmonella enterica serovars typhi, Salmonella typhimurium, Candida albicans, Aspergillus flavus, Fusarium solani, and Cryptococcus neoformans.

Extracellular DNA (eDNA) is a common matrix component in microbial biofilms and has been identified in, but not limited to, Acinetobacter baumannii, Actinobacillus actinomycetemcomitans, Bdellovibrio bacterivorous, Bordetella pertussis, Bordetella bronchiseptica, Campylobacter jejuni, Comamonas denitrificans, Escherichia coli, Haemophilus influenza, Klebsiella pneumoniae, Neisseria meningitides, Pseudomonas aeruginosa, Shewanella oneidensis, Vibrio cholera, Gram- positive bacteria, Bacillus licheniformis, Bacillus subtilis, Enterococcus faecalis, Listeria monocytogenes, Micrococcus luteus, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus haemolyticus, Streptococcus anginosus, Streptococcus constellatus, Streptococcus salivarius, Staphylococcus lugdunesis, Streptococcus intermedius, Streptococcus intermedius, Streptococcus mutans, Streptococcus pneumoniae, Streptococcus pyogenes, Aspergillus fumigatus and Candida albicans.

Most biofilms comprises biofilm or EPS from bacteria of many different species and are thus "poly-cultural".

Clade a group of polypeptides clustered together based on homologous features traced to a common ancestor. Polypeptide clades can be visualized as phylogenetic trees and a clade is a group of polypeptides that consists of a common ancestor and all its lineal descendants e.g. the Terribacillus clade or clade of Terribacillus is a group of enzymes all related to the same ancestor and share common properties.

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.

Cleaning adjunct ingredient: The cleaning adjunct ingredient is an ingredient which is different from the enzymes comprised in the cleaning composition of this invention. The term includes the term "cleaning component" and is defined herein to mean the types of components which can be used in cleaning compositions. Examples of cleaning components are alkalis, surfactants, hydrotropes, builders, co-builders, chelators or chelating agents, bleaching system or bleach components, polymers, fabric hueing agents, fabric conditioners, foam boosters, suds suppressors, dispersants, dye transfer inhibitors, fluorescent whitening agents, perfume, optical brighteners, bactericides, fungicides, soil suspending agents, soil release polymers, anti-redeposition agents, enzyme inhibitors or stabilizers, enzyme activators, antioxidants and solubilizers.

Cleaning composition: The term "cleaning composition" refers to compositions that find use in the removal of undesired compounds from textiles to be cleaned. The term includes detergent compositions. The cleaning composition may be used to e.g. clean textiles for both household cleaning and industrial cleaning. The terms encompass any materials/compounds selected for the cleaning composition desired and the form of the product (e.g., liquid, gel, powder, granulate, paste, or spray compositions) and includes, but is not limited to, detergent compositions (e.g., liquid and/or solid laundry detergents and fine fabric detergents; fabric fresheners; fabric softeners; and textile and laundry pre-spotters/pretreatment). In addition to containing the enzymes of the invention, the cleaning composition may contain one or more additional enzymes (such as proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidaes, haloperoxygenases, catalases and mannanases, or any mixture thereof), and/or cleaning components such as 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, anti- corrosion agents, enzyme inhibitors or stabilizers, enzyme activators, transferase(s), hydrolytic enzymes, oxido reductases, bluing agents and fluorescent dyes, antioxidants, and solubilizers.

Deep cleaning: By the term "deep cleaning" is meant reduction or removal of components of biofilm, such as EPS or parts hereof, polysaccharides, PNAG (poly-N-acetylglucosamine), proteins, DNA, soil or other components present in the biofilm.

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 components such as hydrogen peroxide or other peroxides.

Fungal: In the context of the present invention the term "fungal" in relation to polypeptide (such as an enzyme, e.g. a DNase) refers to a polypeptide encoded by and thus directly derivable from the genome of a fungus, where such fungus has not been genetically modified to encode said polypeptide, e.g. by introducing the encoding sequence in the genome by recombinant DNA technology. In the context of the present invention, the term "fungal DNase" or "polypeptide having DNase activity obtained from a fungal source" or "polypeptide is of fungal origin" thus refers to a DNase encoded by and thus directly derivable from the genome of a fungal species, where the fungal species has not been subjected to a genetic modification introducing recombinant DNA encoding said DNase. Thus, the nucleotide sequence encoding the fungal polypeptide having DNase activity is a sequence naturally in the genetic background of a fungal species. The fungal polypeptide having DNase activity encoding by such sequence may also be referred to a wildtype DNase. In one aspect of the invention the enzyme having DNase activity is substantially homologous to a fungal DNase. In the context of the present invention, the term "substantially homologous" denotes a polypeptide having DNase activity which is at least 80%, preferably at least 85%, more preferably at least 90%, more preferably at least 95%, even more preferably at least 96%, 97%, 98%, and most preferably at least 99% identical to the amino acid sequence of SEQ ID NO 2.

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 enzymes of the invention. The fermentation broth from that host cell will comprise the isolated polypeptide.

Laundering: The term "laundering" relates to both household laundering and industrial laundering and means the process of treating textiles with a solution containing a cleaning or detergent composition of the present invention. The laundering process can for example be carried out using e.g. a household or an industrial washing machine or can be carried out by hand.

Malodor: By the term" malodor" is meant an odor which is not desired on clean items. The cleaned item should smell fresh and clean without malodors adhered to the item. One example of malodor is compounds with an unpleasant smell, which may be produced by microorganisms. Another example is unpleasant smells can be sweat or body odor adhered to an item which has been in contact with human or animal. Another example of malodor can be the odor from spices, which sticks to items such as curry or other exotic spices which smell strongly.

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 et al., 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) 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, 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, rabbit and silk or synthetic polymers such as nylon, aramid, polyester, acrylic, polypropylene and spandex/elastane, or blends thereof as well as blends 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 fiber (e.g. polyamide fiber, acrylic fiber, polyester fiber, polyvinyl chloride fiber, polyurethane fiber, polyurea fiber, aramid fiber), and/or cellulose-containing fiber (e.g. rayon/viscose, ramie, flax/linen, jute, cellulose acetate fiber, 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. In the context of the present invention, the term "textile" also covers fabrics.

Variant: The term "variant" means a polypeptide/enzyme having the same activity as the parent enzyme comprising an alteration, i.e., a substitution, insertion, and/or deletion, at one or more positions. A substitution means replacement of the amino acid occupying a position with a different amino acid; a deletion means removal of the amino acid occupying a position; and an insertion means adding an amino acid adjacent to and immediately following the amino acid occupying a position. In the context of the present invention, a variant may be a variant of an identified DNase that has the enzymatic activity of the parent, i.e. the capacity of catalyzing the hydrolytic cleavage of phosphodiester linkages in the DNA backbone (deoxyribonuclease activity). In one embodiment, the deoxyribonuclease activity of the variant is increased with reference to the parent DNase, e.g. the polypeptide of SEQ ID NO: 2. In the context of the present invention, a variant may also be a variant of an identified hexosaminidase that has the enzymatic activity of the parent, i.e. the capacity of catalyzing the hydrolysis of β-1 ,6-glycosidic linkages of N-acetyl-glucosamine polymers (hexosaminidase activity). In one embodiment, the hexosaminidase activity of the variant is increased with reference to the parent hexosaminidase, e.g. the polypeptide of SEQ ID NO: 14.

Wash cycle: The term "wash cycle" is defined herein as a washing operation wherein textiles are immersed in the wash liquor, mechanical action of some kind is applied to the textile in order to release stains and to facilitate flow of wash liquor in and out of the textile and finally the superfluous wash liquor is removed. After one or more wash cycles, the textile is generally rinsed and dried.

Wash liquor: The term "wash liquor" is intended to mean the solution or mixture of water and at least a surfactant, optionally including other detergent components e.g. enzymes other than the enzyme having DNase activity, and which is used for laundering textiles.

Wash performance: One way of measuring the wash performance is the Delta enzyme performance value (ARem enzyme value): The term "Delta enzyme remission value" is defined herein as the result of a reflectance or remission measurement at 460 nm. The remission value of a swatch is measured and compared to a swatch of similar colour as background, preferably a swatch from a repetition wash, with a swatch representing each type being measured before wash. The Delta enzyme remission is the remission value of the swatch washed in detergent with an enzyme present minus the remission value of a similar swatch washed in a detergent without enzyme present.

Another way of measuring the wash performance is by use of the Color difference (L value):

A Lab color space is a color-opponent space with dimension L for lightness. The L value, L*, represents the darkest black at L* = 0, and the brightest white at L* = 100. In the context of the present invention L value is also referred to as color difference.

Whiteness: The term "whiteness" is defined herein as e.g. greying or yellowing e.g. textiles. Greying and yellowing can be due to soil redeposition, body soils, colouring from e.g. iron and copper ions or dye transfer.

Detailed Description of the Invention

It was surprisingly found that washing textiles with an enzyme having DNase activity (DNase) in combination with an enzyme having hexosaminidase activity (Hexosaminidase) gives a surprisingly good result with regard to deep cleaning e.g., reduction/removing of biofilm components, maintaining whiteness and reducing redeposition of soil and malodor. A wide range of bacterial and fungal microorganisms have been found to produce PNAG or PNAG-like surface polysaccharides and most biofilms will comprise some amount of PNAG or PNAG-like surface polysaccharides since many different ubiquitous bacteria possess the ability to produce PNAG. DNA is also present in many biofilms. Therefore, DNA and PNAG is usually present in a biofilm including biofilms associated with cleaning such as laundry, washing machines, hard surfaces e.g. utensils etc. The present invention has therefore wide applications. One aspect of the invention relates to the use of a composition e.g. cleaning composition comprising a combination of an enzyme having DNase activity (DNase) and an enzyme having hexosaminidase activity (Hexosaminidase) for deep cleaning of an item e.g. reducing/removing biofilm components, wherein the biofilm components comprises PNAG and DNA. The biofilm components may be associated with textiles, such as clothing, washing machines, hard surfaces e.g. in ADW.

In one aspect, the biofilm or EPS producing strain is Staphylococcus epidermidis. In one aspect the biofilm or EPS producing strain is Pseudomonas alcaliphila or Pseudomonas fluorescens. In one aspect, the biofilm or EPS producing strain is Staphylococcus aureus. As described, adding a combination of enzymes having hexosaminidase activity e.g. Dispersins together with a DNase e.g. from A. Oryzae, such as a DNase with SEQ ID NO 2 or having at least 60% sequence identity hereto, is advantageous as the complex construction of biofilms gives rise to hidden pockets of PNAG and DNA inside the biofilm, pockets that are not available when only one enzyme is added. Applying the composition comprising the enzyme combination of the present invention provides better deep cleaning effect than by adding the single specificities. Surprisingly, it was found that adding a composition comprising the enzyme having hexosaminidase activity and the enzyme having DNase activity at the same time provides a synergistic effect e.g. as each enzymes' specific action releases more biofilm component than if the enzymes were added separately, see e.g. example 2 and 3. Thus, one aspect of the invention relates to the use of a composition comprising a hexosaminidase and a DNase for deep cleaning of an item, wherein a synergistic deep cleaning effect is obtained.

Further, this synergistic effect was shown in a detergent on e.g. on textiles such as laundry items. In one aspect of the invention the combination of the enzyme having hexosaminidase activity e.g. the dispersins and the enzyme having DNase activity e.g. the A. oryzae DNase provides synergistic deep cleaning effect in a detergent and is thus particularly useful in cleaning applications such as laundry and hard surface cleaning e.g. ADW (automatic dish washing).

One aspect relates to a method for laundering an item comprising the steps of:

a) Exposing an item to a wash liquor comprising an enzyme having DNase activity and enzyme having hexosaminidase activity or a composition according to the invention;

b) Completing at least one wash cycle; and

c) Optionally rinsing the item.

One aspect of the invention relates to a method of laundering a textile, comprising the steps of: a) Contacting the textile with a wash liquor comprising an enzyme having DNase activity, an enzyme having hexosaminidase activity and a surfactant; and

b) optionally rinsing the textile,

wherein the enzyme having DNase activity and the hexosaminidase activity have deep cleaning properties.

In a wash liquor the concentration of each of the DNase and hexosaminidase is preferably at least 0.00001 mg/L or at least 0.0001 or at least 0.001 mg/L of enzyme or at least 0.01 , 0.02, 0.05, 0.1 , 0.2, 0.5, 1 , 2, 5, 10 or at least 15 μg active enzyme per liter of wash liquor. Optionally the concentration of enzyme in the wash liquor is in the range of about 0.00002 mg/L to about 2 mg/L, about 0.0002 mg/L to about 2 mg/L, about 0.002 mg/L to about 2 mg/L, such as about 0.02 mg/L to about 2 mg/L, such as about 0.2 mg/L to about 2 mg/L or in the range of about 0.00001 mg/L to about 1 mg/L, about 0.0001 mg/L to about 1 mg/L, about 0.0001 mg/L to about 10 mg/L or in the range of in the range of about 0.001 mg/L to about 10 mg/L, or in the range of about 0.01 mg/L to about 10 mg/L, or in in the range of about 0.1 mg/L to about 10 mg/L per liter of wash liquor.

In one aspect, the biofilm comprises at least one bacterium having the polysaccharide poly-

N-acetylglucosamine (PNAG) on the outer surface. In one aspect, such bacteria are Pseudomonas fluorescens. In one aspect such bacteria is staphylococcus aureus and the biofilm or EPS comprises PNAG. Enzymes having hexosaminidase activity, such as Dispersins, hydrolyze β-1 ,6-glycosidic linkages of N-acetyl-glucosamine polymers, and compositions comprising Dispersin B (DspB) is described in WO200406117. However, to be useful in cleaning processes enzymes need to perform their action under the conditions of cleaning processes such as laundry, which includes stability in the presence of cleaning components such as surfactants, builders and bleach components. There is no indication in the art of the use of hexosaminidases, such as dispersins, in combination with DNases in cleaning processes such as laundry or in detergent compositions comprising adjuncts e.g. surfactants, builders and/or bleaches.

Thus, some aspects of the invention relate the use of an enzyme having DNase activity and an enzyme having hexosaminidase activity in a cleaning process. Some aspects of the invention relates to cleaning compositions comprising a) an enzyme having DNase activity and an enzyme having hexosaminidase activity and b) at least one surfactant, preferably at least one surfactant selected from the group consisting of anionic, nonionic and/or cationic surfactants.

Some aspects of the present invention relate to laundry or cleaning compositions comprising a DNase and a hexosaminidase enzyme, preferably at a level of from about 0.000001 wt% to about 1 wt%, from about 0.0001 wt% to about 1 wt%, from about 0.0002 wt% to about 1 wt%, from about 0.0005 wt% to about 1 wt%, from about 0.001 wt% to about 1 wt%, from about 0.002 wt% to about 1 wt%, from about 0.005 wt% to about 1 wt%, preferably from about 0.01 wt% to about 0.5 wt%, preferably from 0.0002 wt% to about 1 wt% by weight (wt%) of the composition. The amounts are wt% per unit active enzyme e.g. from about 0.00001 wt% to about 1 wt% of DNase by weight of the composition and from about 0.00001 wt% to about 1 wt% of hexosaminidase by weight of the composition.

The concentration of the active enzyme having hexosaminidase activity is preferably at least

0.00001 %, preferably at least 0.00002%, preferably at least 0.0001 wt%, preferably at least 0.0002 wt%, preferably at least 0.001 wt %, preferably at least 0.002 wt %, preferably at least 0.005 wt %, preferably at least 0.01 wt %, preferably at least 0.02 wt %, preferably at least 0.05 wt % preferably at least 0.1 wt % of the total detergent concentration.

The concentration of the active enzyme having DNase activity is preferably at least

Thus, in one aspect the amount of DNase in the composition is at least 0.00001 ppm, 0.00002 ppm, 0.00005 ppm, 0.0001 ppm, 0.0002 ppm, 0.0005 ppm, 0.001 ppm, 0.002 ppm, 0.005 ppm, 0.01 ppm, 0.02 ppm, 0.05 ppm, 0.1 ppm, 0.2 ppm, 0.5 ppm, 1 ppm, 2 ppm, 5 ppm, 10 ppm or at least 20 ppm DNase enzyme. In one aspect, the amount of DNase in the composition is in the range from about 0.00001 ppm to about 10 ppm, or in the range from about 0.0001 ppm to about 2 ppm or in the range from about 0.001 ppm to about 2 ppm DNase enzyme.

Any bleaching system comprising components known in the art for use in cleaning detergents may be utilized. Suitable bleaching system components include sources of hydrogen peroxide; sources of peracids; and bleach catalysts or boosters.

Sources of hydrogen peroxide

Suitable sources of hydrogen peroxide are inorganic persalts, including alkali metal salts such as sodium percarbonate and sodium perborates (usually mono- or tetrahydrate), and hydrogen peroxide-urea (1/1 ).

Sources of peracids

Peracids may be (a) incorporated directly as preformed peracids or (b) formed in situ in the wash liquor from hydrogen peroxide and a bleach activator (perhydrolysis) or (c) formed in situ in the wash liquor from hydrogen peroxide and a perhydrolase and a suitable substrate for the latter, e.g., an ester.

a) Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids such as peroxybenzoic acid and its ring-substituted derivatives, peroxy-a-naphthoic acid, peroxyphthalic acid, peroxylauric acid, peroxystearic acid, ε-phthalimidoperoxycaproic acid [phthalimidoperoxyhexanoic acid (PAP)], and o-carboxybenzamidoperoxycaproic acid; aliphatic and aromatic diperoxydicarboxylic acids such as diperoxydodecanedioic acid, diperoxyazelaic acid, diperoxysebacic acid, diperoxybrassylic acid, 2-decyldiperoxybutanedioic acid, and diperoxyphthalic, -isophthalic and - terephthalic acids; perimidic acids; peroxymonosulfuric acid; peroxydisulfuric acid; peroxyphosphoric acid; peroxysilicic acid; and mixtures of said compounds. It is understood that the peracids mentioned may in some cases be best added as suitable salts, such as alkali metal salts (e.g. , Oxone®) or alkaline earth-metal salts.

b) Suitable bleach activators include those belonging to the class of esters, amides, imides, nitriles or anhydrides and, where applicable, salts thereof. Suitable examples are tetraacetylethylenediamine (TAED), sodium 4-[(3,5,5-trimethylhexanoyl) oxy] benzene-1 -sulfonate (ISONOBS), sodium 4-(dodecanoyloxy) benzene-1 -sulfonate (LOBS), sodium 4-(decanoyloxy) benzene-1 -sulfonate, 4-(decanoyloxy) benzoic acid (DOBA), sodium 4-(nonanoyloxy) benzene-1 - sulfonate (NOBS), and/or those disclosed in W098/17767. A family of bleach activators of interest was disclosed in EP624154 and particularly preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like triacetin has the advantage that they are environmentally friendly. Furthermore, acetyl triethyl citrate and triacetin have good hydrolytic stability in the product upon storage and are efficient bleach activators. Finally, ATC is multifunctional, as the citrate released in the perhydrolysis reaction may function as a builder.

Preferably the hexosaminidase is selected from the Curtobacterium clade or the Terribacillus clade, most preferably the hexosaminidase is selected from the Terribacillus clade.

The enzymes having DNase activity to be used in the cleaning composition of the invention, which are useful for deep cleaning of items such as hard surfaces, textiles and/or fabric, are preferably selected from DNase which is obtainable from a fungus. A DNase which is obtainable from an Aspergillus is preferred; a DNase which is obtainable from Aspergillus oryzae is preferred. In one embodiment of the present invention, the enzyme having deoxyribonuclease activity is not the S1 nuclease from Aspergillus oryzae.

The DNase used in the present invention preferably includes the polypeptide having SEQ

ID NO: 2, which is obtained from Aspergillus oryzae. One aspect of the present invention relates to isolated enzymes having a sequence identity to the mature polypeptide of SEQ ID NO: 2 of at least 60%, e.g., at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 91 %, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100%, and which have DNase activity. Biofilm can develop on textile when microorganisms are present on an item and stick together on the item. This biofilm may adhere soil due to its sticky nature.

The present invention concerns the use of a cleaning composition comprising an enzyme having DNase activity and an enzyme having hexosaminidase activity for deep cleaning of an item, wherein the DNase is an enzyme having at least 60% sequence identity to the amino acid sequence having SEQ ID NO: 2, wherein the hexosaminidase is an enzyme having at least 60% sequence identity to the amino acid sequence having SEQ ID NO: 3, 4, 5, 6, 7, 8, 9, 10, 1 1 , 12, 13, 14, 15, 16, 17, 18, 19 or 20 and wherein the item is a textile. In one aspect of the invention the cleaning composition is used for preventing, reducing or removing the stickiness of an item. The cleaning composition can further be used for pre-treating stains on textile such as textile with a pronounced amount of biofilm adhered to the textile.

Additionally, the invention concerns use of the cleaning composition for preventing, reducing or removing re-deposition of soil during a wash cycle. When the cleaning composition is used for example in the laundering of textile, the cleaning composition hinders deposition of soil present in the wash liquor on the textile.

Further, the invention concerns the use of a cleaning composition for preventing, reducing or removing the adherence of soil to an item. In one embodiment, the item is textile. When the soil does not adhere to the item, the item appears cleaner. Thus, the invention further concerns the use of a cleaning composition according to the invention for maintaining or improving the whiteness of the item.

When items like T-shirts or sportswear are used, they are exposed to bacteria from the body of the user and from the rest of the environment in which they are used. This may cause malodor on the item even after the item is washed. The present invention therefore also concerns removal or reduction of malodor on textile. The malodor may be caused by bacteria producing compounds with an unpleasant smell. One example of such unpleasant smelling compounds is E-2-nonenal. The malodor can be present on newly washed textile which is still wet, or the malodor can be present on newly washed textile which has subsequently been dried. The malodor may also be present on textile which has been stored for some time after wash.

The enzyme having DNase activity and the enzyme having hexosaminidase activity 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 NhU* 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 laundry soap bar may be processed in conventional laundry soap bar making equipment such as but not limited to: mixers, plodders, e.g a two stage vacuum plodder, extruders, cutters, logo- stampers, cooling tunnels and wrappers. The invention is not limited to preparing the laundry soap bars by any single method. The premix may be added to the soap at different stages of the process. For example, the premix containing a soap, enzymes 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 the mixture is then plodded. The enzymes 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

Mini Launder-O-Meter (MiniLOM) Model Wash System

MiniLOM is a mini wash system in which washes are performed in 50 ml test tubes placed in a Stuart rotator. Each tube simulates one small washing machine and during an experiment, each will contain a solution of a specific detergent/enzyme system to be tested along with the soiled and unsoiled fabrics it is tested on. Mechanical stress is achieved via rotation (typically 20rpm), and the temperature is controlled by placement of the rotator in a heating cabinet/room.

Examples

Assay I: testing of hexosaminidase activity

The hexosaminidase activity of the polypeptides listed in the table below was determined using 4- nitrophenyl N-acetyl-3-D-glucosaminide (Sigma-Aldrich) as substrate. The enzymatic reaction was performed in triplicate in a 96 well flat bottom polystyrene microtiter plate (Thermo Scientific) with the following conditions: 50 mM 2-(N-morpholino) ethanesulfonic acid pH 6 buffer, 1.5 mg/ml 4- nitrophenyl N-acetyl-3-D-glucosaminide and 10, 20 or 50 μg/ml purified enzyme sample in a total reaction volume of 100 μΙ. Blank samples without polypeptide were run in parallel. The reactions were carried out at 37°C in a Thermomixer comfort (Eppendorf). After 10 minutes of incubation, 5 μΙ 1 M NaOH was added to each reaction mixture to stop the enzymatic reaction. The absorbance was read at 405 nm using a POLARstar Omega plate reader (BMG LABTECH) to estimate the formation of 4- nitrophenolate ion released because of enzymatic hydrolysis of the 4-nitrophenyl N-acetyl-3-D- glucosaminide substrate. The results are summarized in table 1 below. The table shows the average absorbance measured at 405 nm for each reaction performed in triplicate. It is seen that the absorbance is higher for the reaction carried out with all the polypeptides listed in the table below compared to blank without polypeptide which demonstrates that all the tested polypeptides exhibit hexosaminidase activity. Table 1. Hexosaminidase activity.

Assay II

Testing of DNase activity

DNase activity was determined on DNase Test Agar with Methyl Green (BD, Franklin Lakes,

NJ, USA), which was prepared according to the manual from the supplier. Briefly, 21 g of agar was dissolved in 500 ml water and then autoclaved for 15 min at 121 °C. Autoclaved agar was temperated to 48°C in a water bath, and 20 ml of agar was poured into petridishes and allowed to solidify by incubation overnight at room temperature. On solidified agar plates, 5 μΙ of enzyme solutions are added, and DNase activity is observed as colorless zones around the spotted enzyme solutions.

Assay Ma

DNase activity was determined by fluorescence using fluorescence-quenched DNA oligonucleotide probe. This probe emits signal after nuclease degradation according to the manual from the supplier (DNase alert kit, Integrated DNA Technology, Coralville, Iowa, USA). Briefly, 5μΙ of the substrate was added to 95 μΙ of DNase. If the signal was too high, further dilutions of DNase was done in the adequate buffer. Kinetic curve was measured for 20 min at 22°C using a Clariostar microplate reader (536nm excitation, 556nm emission).

Assay III

Wash performance is expressed as a delta remission value (ARem). After washing and rinsing the swatches were spread out flat and allowed to air dry at room temperature overnight. All washes are evaluated the day after the wash. Light reflectance evaluations of the swatches were done using a Macbeth Color Eye 7000 reflectance spectrophotometer with very small aperture. The measurements were made without UV in the incident light and remission at 460 nm was extracted. Measurements were made on unwashed and washed swatches. The test swatch to be measured was placed on top of another swatch of same type and color (twin swatch). With only one swatch of each kind per beaker, a swatch from a replicate wash was used in this way. Remission values for individual swatches were calculated by subtracting the remission value of the unwashed swatch from the remission value of the washed swatch. The total wash performance for each stained swatch set was calculated as the sum of individual ARem.

Calculating the enzyme effect is done by taking the measurements from washed swatches with enzymes and subtracting with the measurements from washed swatches without enzyme for each stain. The total enzyme performance is calculated as the sum of individual ARem_enzyme.

Example 1 :

Extraction of EPS (extracellular polymeric substances) from Pseudomonas fluorescens

A Pseudomonas fluorescens isolate from Iceland was used as a model microorganism in the present example. Pseudomonas fluorescens was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131 ; Oxoid Ltd, Basingstoke, UK) and incubated for 1 day at 23°C. The strain was inoculated into 10 mL of TSB and the culture was incubated with shaking for 16 hours at 23°C. The overnight culture was diluted (1 :100) in 200ml M63 supplemented medium (15mM (NH₄)2S0₄, 100mM KH2PO4, 1.8μΜ FeS0₄, 1 mM MgS0₄.7H₂0, 0.4% (w/v) glycerol, 0.2% (w/v) Casamino acids and 0.0001 % (w/v) Thiamine) added to a Corning® CellBIND® 225cm² Angled Neck Cell Culture Flask with Vent Cap and incubated statically for 5 days at 23°C. The biofilm culture was subsequently transferred to four 50ml Falcon tubes and pelleted by centrifugation (10 min, 8000g, 25°C), and the supernatants were discarded completely. The residual pellets from each Falcon tube were resuspended in 0.450 ml 3M NaCI to extract the surface-associated EPS (extracellular polymeric substances) and pooled in one test tube (5ml, Eppendorf). The suspension was centrifuged at 5000g for 10 min at 25°C and the 1.8 ml supernatant was transferred to a new test tube as EPS fraction and stored at -20°C until further use (termed crude EPS).

Fluorescent assay with WGA-Alexa Fluor® 488

50ul aliquots of the crude EPS were spotted on two wells of a Nunc microtiter plate and incubated at room temperature for 45 min. Supernatant was then removed and 50ul of PBS buffer was added to one well and 50ul containing 20 ppm of enzyme (SEQ ID NO 14) was added to the other well. The plate was incubated 1 hour at 30 °C. Next, supernatants were removed and 50ul of 10ug/ml of wheat germ agglutinin WGA-Alexa fluor488 fluorescent conjugate (Thermo Fischer Scientific, #W1 1261 ) was added to the wells. Alexa Fluor® 488 WGA binds to sialic acid and A/-acetylglucosaminyl residues. The plate was incubated at room temperature for 15 min. Samples were washed with 50ul water and the fluorescence at

nm was measured with a SpectraMax M3 plate reader instrument. The measurements obtained are listed below in table 2.

Table 2. Fluorescent measurements of crude EPS from P. fluorescence treated with or without hexosaminidase (SEQ ID NO 14) stained with WGA-Alexa Fluor488 dye.

Results from the fluorescent measurements show that the crude EPS sample from P. fluorescence is stained with WGA-Alexa Fluor488 suggesting that it contains poly N-acetyl-glucosamine (PNAG) and is sensitive to hexosaminidase hydrolysis.

DNA content analysis by agarose gel electrophoresis

10ul aliquot of the crude EPS was treated with and without DNase (2ppm, SEQ ID NO 2) and subsequently subjected to agarose gel electrophoresis. The gel was stained with SyBrSafe (Invitrogen). In the EPS sample, a prominent band with a high molecular mass was detected in the 1 % agarose gel corresponding to DNA. In contrast, in the EPS sample treated with DNase a prominent band with a small molecular mass was detected corresponding to small degradation fragments of DNA. The present study indicates that the crude EPS sample from P. fluorescens contained DNA and that it was degraded by DNase treatment. Example 2:

Synergistic effect between hexosaminidase and DNase on deep-cleaning in liquid model detergent

50ul aliquots of the crude EPS described in Example 1 were spotted on sterile textile swatches (WFK20A) and incubated for 30 min at ambient temperature. The swatches (sterile or with EPS) were placed in 50 ml. test tubes and 10 ml. of wash liquor (15°dH water with 0.2 g/L iron(lll) oxide nano- powder (544884; Sigma-Aldrich) with 3.33g/L liquid model A detergent) and 0.2 μg/ml enzyme(s) was added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 37°C at 20rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15°dH water and dried on filter paper over night. The remission (REM^460nm) values were measured using a Macbeth Color-Eye 7000 (CE7000), and are displayed in table 3. Delta values (REM^460nm (swatch washed with enzyme) - REM^460nm (swatch washed without enzyme)) are also indicated.

Table 3. Synergistic effect between hexosaminidase with SEQ ID NO 14 and DNase with SEQ ID NO 2 in deep-cleaning in model A detergent.

As seen in table 3, the wash performance of the enzyme cocktail comprising hexosaminidase (SEQ ID NO 14) and DNase (SEQ ID NO 2) (AREM460nm (cocktail) =35.2) significantly exceeds the sum of the performances seen for of the individual enzymes (AREM460nm (sum of individual enzyme treatments) = 29.5), showing a synergetic effect between the enzymes. This also suggests that the different EPS components targeted by these enzymes are part of complex macromolecular structures, which shield other matrix components from enzymatic hydrolysis.

Example 3

A Pseudomonas fluorescens isolate from Iceland was used as a model microorganism in the present example. Pseudomonas fluorescens was restreaked on Tryptone Soya Agar (TSA) (pH 7.3) (CM0131 ; Oxoid Ltd, Basingstoke, UK) and incubated for 1 day at 23°C. A single colony was inoculated into 10 mL of TSB and the culture was incubated for 16 hours at 23°C with shaking (Tetramax 1000 at 460rpm). After propagation, the culture was diluted to an OD600 of 0.03 in fresh TSB and 1.65 mL aliquots were added to the wells of 12-well polystyrene flat-bottom microplates (3512; Costar, Corning Incorporated, Corning, NY, USA), in which round swatches (diameter 2 cm) of sterile textile (WFK20A) had been placed. Sterile TSB was added to control wells. After 48h at 23°C (static incubation), the swatches were rinsed twice with 0.9% (w/v) NaCI.

Five rinsed swatches (sterile or with P. fluourescens) were placed in 50 mL test tubes and 10 mL of wash liquor (15°dH water with 0.2 g/L iron(lll) oxide nanopowder (544884; Sigma-Aldrich) with 3.33g/L liquid model A detergent) and 0.2ppm enzymes was added to each tube. Washes without enzyme were included as controls. The test tubes were placed in a Stuart rotator and incubated for 1 hour at 30°C at 20rpm. The wash liquor was then removed, and the swatches were rinsed twice with 15°dH water and dried on filter paper over night. The remission (REM^460nm) values were measured using a Macbeth Color-Eye 7000 (CE7000), and are displayed in table 4.

Delta values (REM⁴⁶⁰ⁿ (swatch washed with enzyme) ^— REM⁴⁶⁰"' ⁷¹ (swatch washed without enzyme)) 3Te alSO indicated.

As seen in table 4, an enzyme cocktail comprising hexosaminidase (SEQ ID NO 13) and DNase (SEQ ID NO 2) provides superior deep-cleaning properties in model A detergent as compared to the individual enzymes. Given that the wash performance of the enzyme cocktail (AREM^460nm (cocktail) =12.3) clearly exceeds the sum of the performances seen for the individual enzymes (AREM^460nm (sum of individual enzyme treatments) = 5.0), this shows a significant synergetic effect between the two enzymes on the deep-cleaning properties in model A.
