Definitions

  • the present invention relates to cleaning compositions comprising at least one polypeptide having RNase activity, a method for cleaning an item and use of the cleaning composition according to the invention.
  • Cleaning of different item can be a challenge, even though cleaning compositions specifically adapted for cleaning of laundry item, hard surfaces and dish ware are on the marked. Many of the commercially available cleaning compositions do not clean the items sufficiently, and some or all items do not appear clean, visually or sensorial.
  • Many cleaning compositions contain enzymes that facilitate the removal of soil and cleaning of the item, e.g. proteases facilitating removal of protein soil.
  • the item can become soiled with many different types of soiling, e.g. complex food stains.
  • Another source of complex soil is body soil that adheres to the clothes, which soil will typically comprise bacteria and which may result in development of malodor.
  • Biofilm is an example of soiling and which may build up on items after being used, e.g. by body soil attaching to clothes. This may provide several disadvantages.
  • Biofilm comprises an extracellular polymeric matrix, composed of e.g. polysaccharides, RNA, extracellular DNA and RNA (exDNA, exRNA), and proteins.
  • the extracellular polymeric matrix may be sticky or gluing, which when present on an item, give rise to redeposition or backstaining of soil resulting in a greying of the item.
  • Biofilm is therefore not desirable on any items: laundry item, hard surfaces and dish ware or on surfaces associated with cleaning, such as the interior of washing machines, dishwashing machines etc. Further, the soil removed from the items during wash or originating from the washing or dishwashing machine, can redeposit on the items. As a result, hereof, some items may be more“soiled” after wash than before wash.

Description

CLEANING COMPOSITION COMPRISING ANIONIC SURFACTANT
AND A POLYPEPTIDE HAVING RNASE 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 cleaning compositions comprising at least one polypeptide having RNase activity, a method for cleaning an item and use of the cleaning composition according to the invention.
Description of the Related Art
Cleaning of different item can be a challenge, even though cleaning compositions specifically adapted for cleaning of laundry item, hard surfaces and dish ware are on the marked. Many of the commercially available cleaning compositions do not clean the items sufficiently, and some or all items do not appear clean, visually or sensorial.
Consumers experiencing for example that a white shirt that has become grey before being worn out may decide to discharge the shirt.
Many cleaning compositions contain enzymes that facilitate the removal of soil and cleaning of the item, e.g. proteases facilitating removal of protein soil. The item can become soiled with many different types of soiling, e.g. complex food stains. Another source of complex soil is body soil that adheres to the clothes, which soil will typically comprise bacteria and which may result in development of malodor.
Biofilm is an example of soiling and which may build up on items after being used, e.g. by body soil attaching to clothes. This may provide several disadvantages. Biofilm comprises an extracellular polymeric matrix, composed of e.g. polysaccharides, RNA, extracellular DNA and RNA (exDNA, exRNA), and proteins. The extracellular polymeric matrix may be sticky or gluing, which when present on an item, give rise to redeposition or backstaining of soil resulting in a greying of the item.
Another drawback is that malodor may be trapped within the organic structure or malodor may even develop from bacteria present in the biofilm. Biofilm is therefore not desirable on any items: laundry item, hard surfaces and dish ware or on surfaces associated with cleaning, such as the interior of washing machines, dishwashing machines etc. Further, the soil removed from the items during wash or originating from the washing or dishwashing machine, can redeposit on the items. As a result, hereof, some items may be more“soiled” after wash than before wash. One example is a new white T-shirt, which is washed with other laundry items, and become greyish after first wash, or a plate being more or differently soiled after wash.
WO 2006/031554 (Novozymes) describes methods for preventing, removing, reducing or disrupting biofilm on a surface. The methods disclosed use alpha-amylases, and no specific RNase and no effect of the use of RNase is disclosed.
As biofilm is a complex mixture of polysaccharides, proteins, RNA, DNA etc. Enzymes can facilitate removal of biofilm are already available. However, there is a need for cleaning compositions, which effectively remove or reduce components of organic soiling e.g. biofilm in cleaning processes such as laundry, dish wash and hard surface cleaning. The object of the present invention is to provide cleaning compositions, which effectively reduce or remove biofilm.
SUMMARY OF THE INVENTION

The term“RNase” is an abbreviation of the term ribonuclease, which means a nuclease or a polypeptide having RNase activity (EC 3.1 .2.7) that catalyzes the degradation of RNA into smaller components. Ribonucleases can be divided into endoribonucleases and exoribonucleases; the present invention relates to e.g. endoribonucleases. For purposes of the present invention, RNase activity is determined according to the procedure 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 RNase activity of the any of the mature polypeptides shown in SEQ ID NOs: 1 , 2, 3, 4,5, 6, 7, 8, 9, 10, 1 1 , 12, 13, 14, 15, 16, 17, 18, 19, 20, 27, 34 or 35.
The term“biofilm” means a film 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 biofilm producing bacteria can be found among species including Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp. On 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, Staphylococcus aureus and Stenotrophomonas sp.
The term “deep cleaning” means in this context disruption, reduction or removal of organic components such as polysaccharides, proteins, RNA, DNA, soil or other components present in organic matter e.g. biofilm.
Cleaning component: The cleaning component e.g. a detergent ingredient is different to the polypeptides of this invention. The precise nature of these additional cleaning components, and levels of incorporation thereof, will depend on the physical form of the composition and the nature of the operation for which it is to be used. Suitable cleaning components include, but are not limited to the components described below such as surfactants, builders, flocculating aid, chelating agents, dye transfer inhibitors, enzymes, enzyme stabilizers, enzyme inhibitors, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, structure elasticizing agents, fabric softeners, carriers, hydrotropes, builders and co-builders, fabric huing agents, anti-foaming agents, dispersants, processing aids, and/or pigments.
Cleaning Composition: The term cleaning composition includes“detergent composition” and refers to compositions that find use in the removal of undesired compounds from items to be cleaned, such as textiles, dish ware and hard surfaces. The detergent 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 particular type of 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 RNase of the invention, the cleaning composition may contain one or more additional enzymes (such as DNases, proteases, amylases, lipases, cutinases, cellulases, endoglucanases, xyloglucanases, pectinases, pectin lyases, xanthanases, peroxidaes, haloperoxygenases, catalases, galactanase, mannanases, or any mixture thereof), and/or cleaning components such as surfactants, builders, chelators or chelating agents, bleach system or bleach components, polymers, 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.
Dishware: The term dish ware is intended to mean any form of kitchen utensil, dinner set, tableware or crockery made of any kind of suitable material. Dish ware includes, but is not limited to plates, cups, glasses, bowls, all forms of cutlery such as spoons, knives, forks and serving utensils, cooking utensils and the like. They can be made of any kind of suitable material such as ceramics, plastics, metals, china, glass and acrylics.
Dish wash: The term "dish wash" refers to all forms of washing dishes, e.g. by hand (MDW) or automatic dish wash (ADW).
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.
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).
HQ-tag: A“His-tag” refers to a polyhistidine tag typically comprising at least 6 histidine residues, that may be added to the N- or C-terminal. His-tags are known in the art for use in e.g. protein purification but may also be used for improving solubility at low pH values. Similarly, an “HQ-tag”, i.e. a histidine-glutamine tag, may also be used for the purpose of purification as is known in the art.
Improved wash performance: The term“improved wash performance” is defined herein as an enzyme displaying an increased wash performance in a detergent composition relative to the wash performance of same detergent composition without the enzyme e.g. by increased stain removal or less re-deposition. The term “improved wash performance” includes wash performance in laundry, hard surface and dish washing.
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.
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 and trapped within a biofilm or stick to the“glue” of a biofilm. Other examples of unpleasant smells are sweat or body odor adhered to an item which has been in contact with a human or animal. Other examples of malodor are odors from spices which stick to items, for example curry or other exotic spices with a strong smell. 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.
Nomenclature: For purposes of the present invention, the nomenclature [E/Q] or [EQ] means that the amino acid at this position may be a glutamic acid (Glu, E) or a glutamine (Gin, Q). Likewise, the nomenclature [V/G/A/l] or [VGAI] means that the amino acid at this position may be a valine (Val, V), glycine (Gly, G), alanine (Ala, A) or isoleucine (lie, I), and so forth for other combinations as described herein.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to cleaning composition comprising one or more anionic surfactants and a polypeptides having RNase activity, i.e. RNases.
The advantage of the present cleaning composition is that it is useful in cleaning items such as textiles, which may comprise body soiling such as cell debris, dead cells, sebum, sweat and other organic staining.
The polypeptide having RNase activity is useful in cleaning surfaces comprising RNA stains and when provided in a cleaning composition together with one or more anionic surfactants, the cleaning effect is even better, as the surfactant facilitates the polypeptides access to the stain. Actually, the cleaning composition of the invention does not only clean the surface of a soiled item. The cleaning composition is effective in deep cleaning of surfaces, e.g. textiles.
Organic stains such as cell debris, sebum and biofilm may be sticky or gluing and may attract soil components to stick to the biofilm. Thus, an item soiled with organic stains may look grey or dirty, as different kinds of soil stick to the stains e.g. stains related to body soil or biofilm. The cleaning composition of the present invention is effective in preventing, removing or reducing the stickiness of an item and is also effective in removing or reducing the greying of the item and maintaining or improving the whiteness of the item.
During wash, dead cells or other body soiling may be released or removed from the item and can redeposit on same or other items, which may result in greying of the item. One example is laundering of a new white t-shirt together with clothes that have been worn and washed several times. The stains from the worn clothes may stick to the new t-shirt and result in greying of the t-shirt. The cleaning composition of the present invention is effective in preventing, reducing or removing redeposition of soil to an item.
Another drawback is that body soiling is that it often causes malodor. The cleaning composition of the invention is therefore useful for prevention, reduction or removal of malodor. Such unsatisfactory cleaning result may result in the consumer buying a new item instead of the cleaned item. This has huge impact on the environment and the cleaning composition of the invention may thus help protecting our environment by causing less damage to the environment, e.g. by reducing waste.
The cleaning composition of the invention may further comprise one or more cleaning composition components, preferably selected from surfactants, builders, bleach components, polymers, dispersing agents and additional enzymes. The cleaning compositions of the invention show improved wash performance. The cleaning composition components are described in more details in the below paragraphs, e.g. paragraphs“builders and Co-builders”,“bleaching systems” etc.
The cleaning composition of the invention comprises from 0.5 to about 80 wt % of anionic surfactant. The presence of one or more anionic surfactants in the cleaning composition ensures an effective cleaning of items soiled with organic stains e.g. body soils.

The cleaning composition of the invention comprises polypeptides having RNase activity. In one embodiment of the invention the polypeptides having RNase activity comprise a domain from the RNase Barnase (Swiss Prot P00648 (SEQ ID NO 27)), PF00545 family) as well as the clusters such as the clades. A clade is a grouping that has a shared phylogeny and includes a common ancestor and all the descendants (living and extinct) of that ancestor (http://evolution.berkeley.edu/evolibrary/article/0_0_0/evo_06). Thus, in the present context a clade refers to a subgroup of closely related RNases. The polypeptides are further described in international patent application number PCT/EP2018/057746 (Novozymes A/S), which is hereby incorporated by reference.
A phylogenetic tree was constructed of polypeptide sequences containing a Barnase domain, as defined in PFAM (PF000545, Pfam version 30.0 Finn (2016). Nucleic Acids Research, Database Issue 44 D279-D285). The phylogenetic tree was constructed from a multiple alignment of mature polypeptide sequences containing at least one Barnase domain. The sequences were aligned using the MUSCLE algorithm version 3.8.31 (Edgar, 2004. Nucleic Acids Research 32(5): 1792-1797), and the trees were constructed using FastTree version 2.1 .8 (Price et al., 2010, PloS one 5(3)) and visualized using iTOL (Letunic & Bork, 2007. Bioinformatics 23(1 ): 127-128). The polypeptides comprising the Barnase domain can be separated into multiple distinct sub-clusters, or clades, where we denoted the clades listed below. Distinct motifs for each clade are described in Example 10 of international patent application number PCT/EP2018/057746 (published as WO2018/178061 ). Examples 1 -5 of PCT/EP2018/057746 describes one way of producing the polypeptides having RNA activity.

In one aspect the invention pertains to a method of cleaning an item comprising the steps of:
(a) Exposing the item to water;
(b) Optionally remove excess of water;
(c) Exposing the item to a wash liquor comprising the cleaning composition of the invention or at least one polypeptide having RNase activity;
(d) Completing at least one wash cycle; and
(e) Optionally rinsing the item;
wherein the item is a textile, a dish ware or a hard surface.
When the item is exposed to water before being exposed to the wash liquor, the item is already wet, and this allows the active components of the wash liquor, e.g. the polypeptide having RNase activity to be exposed to item at a faster rate.
In one embodiment of the invention the cleaning method is a laundry method and the item is a textile, which textile is a hydrophobically-modified textile. The textile may be selected from textiles comprising cotton, polyester, polyamide, polyacryl, silk and mixtures thereof. In one embodiment of the invention the textile is cotton. In one embodiment of the invention the textile is polyester. In one embodiment of the invention the textile is a cotton/polyester mix.
The hydrophobically-modified textile is a textile having thereon a finishing treatment which provides an increase in the hydrophobicity of the textile surface relative to the untreated textile surface. The hydrophobicity increase can be determined by measuring the water contact angle of the textile surface. How to measure the water contact angle and how to provide textiles that are hydrophobically-modified are described in international patent application published under number WO2016/176280 (The Procter & Gamble company), see page 4, line 6 to page 6, line 24.
In one embodiment of the invention the cleaning method is a method for cleaning dish ware, such as automated dish washing (ADW) or dish washing by hand. In another embodiment of the invention the cleaning method cleans hard surfaces, such as floors, walls, or equipment in domestic or industrial kitchens, hospitals or other institutions.
The pH of the wash liquor should be in the range 5.5 to 1 1 , such as in the range of 7 to 9, in the range of 7 to 8 or in the range of 7 to 8.5. The temperature of the wash liquor should be in the range of 5°C to 95°C, or in the range of 10°C to 80°C, in the range of 10°C to 70°C, in the range of 10°C to 60°C, in the range of 10°C to 50°C, in the range of 15°C to 40°C, in the range of 20°C to 40°C, in the range of 15°C to 30°C or in the range of 20°C to 30°C. In one preferred embodiment the temperature of the wash liquor is from about 20°C to about 40°C, such as from about 15°C to about 30°C. The pH and temperature of the wash liquor ensures that the enzymes have optimal conditions and at the same time will be safe to use and friendly to the environment.
In one embodiment of the invention the concentration of the cleaning composition should be such that the concentration of the polypeptide having RNase activity in the wash liquor 0.0002 mg/L to 5 mg/L, such as in the range of 0.002 mg/L to 5 mg/L, in the range of 0.02 mg/L to 2 mg/L, in the range of 0.2 mg/L to 2 mg/L.
In one embodiment of the invention the item is exposed to water and the excess of water is removed before being exposed to the wash liquor. This has the advantage that wash liquor is not diluted with water, when the item is exposed to the wash liquor. One example is a textile that is exposed to water, the excess of water is removed, e.g. by centrifuging, and the textile is then exposed to the wash liquor. Another example is a dish ware being exposed to water, the excess of water is removed by dripping and the dish ware is then exposed to the wash liquor.
In one embodiment of the invention the item is exposed to water and the excess of water is removed by dripping, wringing and/or centrifuging.

Bleaching Systems
The cleaning or the detergent may contain 0-30% by weight, such as about 1 % to about 20%, of a bleaching system. 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-onaphthoic acid, peroxyphthalic acid, peroxylauric acid, peroxystearic acid, e-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-l -sulfonate, 4-(decanoyloxy)benzoic acid (DOBA), sodium 4- (nonanoyloxy)benzene-l -sulfonate (NOBS), and/or those disclosed in W098/17767. A particular 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 hydrolytical 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.
