The present invention is related to variants of fungal serine protease enzyme, which have serine protease activity of Malbranchea protease. Also disclosed are isolated nucleic acid molecules, comprising polynucleotide sequences which encode variants of fungal serine protease enzyme, nucleic acid sequences encoding said protease variants, a host cell and a process of producing polypeptides having serine protease activity. Said protease variants are useful as enzyme preparations applicable in detergent compositions and for treating fibers, wool, hair, leather, or silk, for treating food or feed, or for any applications involving modification, degradation or removal of proteinaceous material.

Cleaning compositions may include a mix of enzymes that include a dispersin and a carbohydrase. Said compositions may be used in cleaning processes and/or for deep cleaning of organic stains.

An ion exchange resin rejuvenation system includes a vessel, a source of a first cleaning solution including an enzyme fluidly connected to the vessel, a source of a second cleaning solution fluidly connected to the vessel, a source of rinse solution connected to the vessel, and a source of a resin regeneration solution fluidly connected to the vessel.

The present disclosure relates to detergent compositions that comprise renewable components and exhibit good performance, as compared to both traditional detergent formulations that contain non-renewable ingredients and known detergent formulations that contain renewable components.

The disclosure relates to products including a polysaccharide derivative wherein the polysaccharide derivative includes a polysaccharide substituted with at least one of: a) at least one sulfate group; b) at least one sulfonate group; c) at least one thiosulfate group; or d) a combination thereof; wherein the polysaccharide is poly alpha-1,3-glucan, poly alpha-1,6-glucan, poly alpha-1,3-1,6-glucan, or a mixture thereof; and the polysaccharide derivative has a degree of substitution of about 0.001 to about 3. The products can be useful as anti-deposition and/or anti-graying agents in laundry detergents, and in home care applications.

A liquid bioactive composition is provided that includes an enzyme with enzymatic activity toward a component of a biological stain. Also provided is a process for facilitating the removal of a biological stain is provided wherein the enzyme in the liquid bioactive coating material is capable of enzymatically degrading of one or more components of the biological stain to facilitate biological stain removal from a substrate.

Disclosed herein are compositions including (A) at least one polymer including (a) a core obtained by reacting a diamine H.sub.2N—Z—NH.sub.2 with a compound having a total number TN of carboxyl groups per molecule in the range of from 3 to 10, where Z is selected from C.sub.3-C.sub.12-cycloalkylene that may be non-substituted or substituted with one or more O—C.sub.1-C.sub.4-alkyl groups and where C.sub.3-C.sub.12-cycloalkylene may bear one to three methyl groups, and where carboxyl groups are selected from COOH and COOX.sup.1 with X.sup.1 being selected from C.sub.1-C.sub.4-alkyl, or two carboxyl groups together form an anhydride group, (b) polyalkylene oxide chains, and (B) at least one hydrolase.

Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

A fluid washing composition with four separate components and laundry washing kit thereof is disclosed. The four components are housed in respective independent tanks of a laundry washing machine equipped with a program for selecting, dosing and differentiated delivering. Component 1 is a detergent formulation with a pH of 4.0-12.0, with high detergent effect in washing programs at temperatures of 40°-60° C., having a specific action on cotton fibers, particularly, whites. Component 2 is a detergent formulation with a pH of 8.0-12.0, with high detergent effect in washing programs at temperatures of 15°-40° C., having a specific action on synthetic, colored and animal-origin fibers. Component 3 is an enzyme-based stain-removing formulation including protease and lipase and possibly amylase with a pH of 5.0-6.0, stabilized with sorbitol and calcium chloride. Component 4 is an after-wash conditioning formulation, with a pH of 2.0-4.0.

The invention provides an enzymatic water-in-oil emulsion, which is suitable for making multi-enzyme blends, and for producing enzymatic detergents.
