Low cost, highly aqueous, thickened heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of surfactant materials, certain viscosity-enhancing agents, and very large amounts of water. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.

The invention relates to a novel amylolytic enzyme extracted from the micro-organism Bacillus sp. A 7-7 (DSM 12368), to sufficiently similar proteins having an amylolytic function, to methods for the production thereof and to diverse fields of application for these proteins. In addition, they can be further developed beyond the implemented fields of application for other, above all, technical purposes. The invention particularly relates to washing and cleaning agents containing amylolytic proteins of the aforementioned type, to methods for cleaning textiles or hard surfaces that involve the use of such amylolytic proteins or analogous agents, and to their use for cleaning textiles or hard surfaces.

The substrate specificity of a lipolytic enzyme can be modified by making alterations to the amino acid sequence in a defined region of the lipolytic enzyme, so as to increase the level of a desired activity or to decrease the level of an undesired activity. Thus, the inventors have developed lipolytic enzyme variants with a modified amino acid sequence with a substrate specificity which can be tailored for specific uses.

Lipolytic enzyme variants

Genes encoding novel cellulases, and a gene encoding a protein that facilitates the action of such novel cellulases, the novel cellulases and a protein that facilitates the action of such cellulases, and enzyme preparations containing such proteins are described. The native hosts and the culture medium of said hosts containing said novel cellulases are also disclosed. These proteins are especially useful in the textile and detergent industry and in pulp and paper industry.

Cellulases, the genes encoding them and uses thereof

Methods for hydrolyzing lignocellulose are provided, comprising contacting the lignocellulose with at least one chemical treatment. Methods for pretreating a lignocellulosic material comprising contacting the material with at least one chemical are also provided. Methods for liberating a substance such as an enzyme, a pharmaceutical, or a nutraceutical from plant material are also provided. These methods are more efficient, more economical, and less toxic than current methods.

Methods to enhance the activity of lignocellulose-degrading enzymes

This invention relates to a process for the treatment of fabrics. More specifically the invention relates to a process for the treatment of fabrics, which process comprises treating the fabric at elevated temperatures with an effective amount of a thermostable lipolytic enzyme.

Treatment of fabrics

An enzyme preparation comprising a modified enzyme selected from the group consisting of an amylase, lipase, oxidoreductase, pectinase or hemicellulase, the modified enzyme having an improved performance due to an alkaline pI and/or increased surface activity obtained by chemical modification or amino acid substitution, is useful eg in detergents, in baking flour, in animal feed, in the manufacture of cellulosic fabrics and for the treatment of lignocellulosic fibers

A one-step process for combined desizing and “stone-washing” of dyed denim, wherein the denim is treated with an amylolytic enzyme in combination with a first abrading monocomponent endoglucanase and a second streak-reducing monocomponent endoglucanase.

A process for combined desizing and 'stone-washing' of dyed denim

A method for obtaining a cellulosic textile fabric having a strongly reduced tendency to pilling formation, preferably corresponding to a pilling note of at least 4, more preferably of at least 4.5, which method comprises treating the fabric with a cellulase capable of performing a partial hydrolysis of the fibre surface corresponding to a < 2 % weight loss based on the untreated cellulosic textile fabric. The cellulase is preferably a 43 kD endoglucanase derived from or producible by Humicola insolens, DSM 1800, SEQ ID NO:1, or a functional analogue of said cellulase such as a variant which is modified by substitution of one or more amino acid residues in one or more of the positions 8, 55, 58, 62, 67, 132, 147, 162, 221, 222, 223, 280; or modified by truncation, preferably genetically truncation, at any position from position 213.

A method of obtaining a cellulosic textile fabric with reduced tendency to pilling formation

The present invention relates to methods for dyeing a material, comprising (a) treating the material with a dyeing system which comprises one or more reduced vat dyes and/or one or more reduced sulfur dyes: and (b) oxidizing the one or more reduced vat dyes or one or more reduced sulfur dyes adsorbed onto the treated material with an oxidation system comprising (i) an oxygen source and one or more enzymes exhibiting oxidase activity or (ii) a hydrogen peroxide source and one or more enzymes exhibiting peroxidase activity, to convert the one or more reduced dyes to their original oxidized insoluble colored forms; wherein the material is a fabric, yarn, fiber, garment or film made of cotton, diacetate, flax, fur, hide, leather, linen, lyocel, polyacrylic, polyamide, polyester, ramie, rayon, silk, tencel, triacetate, viscose or wool.
