The invention provides methods, compositions, systems, and kits that include an enzyme/substrate co-delivery system. The liquid delivery system includes at least one enzyme encapsulated in a water-soluble polymeric matrix and a substrate for the enzyme in a carrier liquid in which the polymeric matrix is insoluble. When water is added, the polymeric matrix is solubilized and enzyme is released from the matrix, permitting catalytic action upon the substrate.

Delivery system for co-formulated enzyme and substrate

A polyesterase enzyme which produces a positive result in an UV and/or MB assay is used to treat polyester to modify polyester properties such as pilling, pilling prevention, weight, feel, appearance and luster.

Enzymes useful for changing the properties of polyester

A method is provided for improving the uptake of a cationic compound onto a polyester article starting material, comprising the steps of: (a) obtaining a polyesterase enzyme; (b) contacting said polyesterase enzyme with said polyester article starting material under conditions and for a time suitable for said polyesterase to produce surface modification of said polyester article starting material and produce a surface modified polyester; (c) contacting said modified polyester article, subsequently or simultaneously with said step (b) with a cationic compound whereby adherence of said cationic compound to said modified polyester is increased compared to said polyester starting material. Also disclosed is a method for increasing the hydrophilicity of a polyester to improve fabric characteristics such as stain resistance, wettability and/or dyeability.

Enzymatic modification of the surface of a polyester fiber or article

A method is provided for reducing the shrinkage of wool comprising the steps of: (a) preparing an aqueous solution comprising an oxidase or a peroxidase; and (b) contacting a wool containing article with said aqueous solution under conditions suitable for reacting said oxidase or peroxidase with said wool.

Process for improved shrink resistance in wool

A mutant cellulase obtainable from Thermomonospora spp is provided which differs from a precursor cellulase in that it has been genetically engineered to introduce a substitution, deletion or addition of an amino acid residue to said precursor cellulase which provided improved activity in a detergent. Preferably, the substitution is at a residue corresponding to T140 in Thermomonospora fusca.
