The present invention relates to random copolymers obtainable by polymerization, the use of said random copolymers as soil release agents in laundry processes. Further aspects of the invention are a method for easier releasing soil from textiles in laundry processes and detergents containing said random copolymers.

Random copolymers as soil release agents in laundry processes

Described are block copolymers which have been prepared by controlled free radical polymerization. Also described is the use of said block copolymers as soil release agents in laundry processes and a process to produce said block copolymers. Further described is a method for easier releasing soil from textiles in laundry processes and a detergent containing said block copolymers.

Block copolymers as soil release agents in laundry processes

The present invention relates to 25 hitherto undescribed genes ofand gene products derived therefrom and all sufficiently homologous nucleic acids and proteins thereof. They occur in five different metabolic pathways for the formation of odorous substances. The metabolic pathways in question are for the synthesis of: 1) isovalerian acid (as part of the catabolism of leucine), 2) 2-methylbutyric acid and/or isobutyric acid (as part of the catabolism of valine and/or isoleucine), 3) butanol and/or butyric acid (as part of the metabolism of butyric acid), 4) propyl acid (as part of the metabolism of propionate) and/or 5) cadaverine and/or putrescine (as parts of the catabolism of lysine and/or arginine). The identification of these genes allows biotechnological production methods to be developed that are improved to the extent that, to assist these nucleic acids, the formation of the odorous substances synthesized via these metabolic pathways can be reduced by deactivating the corresponding genes in the micro-organism used for the biotechnological production. In addition, these gene products are thus available for preparing reactions or for methods according to their respective biochemical properties.

The present invention relates to &#x3b1;-amylase variants that are stabilized to dimerization and/or multimerization, in particular at elevated temperatures or high pH, by point mutagenesis of positively polarized or charged or neutral surface amino acids to give more negatively polarized or charged amino acids. The invention further relates to methods of increasing the stability of an &#x3b1;-amylase to dimerization and/or multimerization brought about by electrostatic interactions whereby at least one amino acid residue on the surface of the starting molecule, which makes a neutral or positively polar or charged contribution to the electrostatic potential of said molecule, is replaced with a more negatively polar or negatively charged amino acid residue. The &#x3b1;-amylase variants obtained thereby exhibit better stability to influences of the solvent, increased processivity, and are suited for numerous industrial areas of use, in particular as active ingredients in detergents and cleansers.

Alpha-amylase variants stabilized against dimerization and/or multimerization, method for the production thereof, and detergents and cleansers containing these alpha-amylase variants

The application describes a stable liquid washing or liquid cleaning agent with an acid-treated cellulose or an acid-treated cellulose derivative. The application further relates to methods of use and preparation of such stable liquid washing or liquid cleaning agents and their anti-greying powers.

Washing or cleaning agent with cellulose or a cellulose derivative

The invention relates to the use of an anionic polymer in a liquid washing or cleaning agent for inhibiting graying when washing and/or cleaning textile web materials, and acrylic acid homopolymers comprising liquid washing and cleaning agents.

Liquid washing or cleaning agent having a polymer preventing graying

The present application relates to washing and cleaning agents, containing phosphate compounds having aliphatic and/or aromatic residues, which act as enzyme stabilizers. Further subjects are the use of such compounds as reversible inhibitors of enzymes, in particular of proteolytic enzymes, and thus as stabilizers in washing or cleaning agents, and further methods and uses correlated therewith.

Washing agent having stabilized enzymes

The present invention relates to &#x3b1;-amylase variants that are stabilized to solvent-exerted hydrolysis, in particular at elevated temperatures or high pH, by point mutagenesis of asparagine (N) or glutamine (Q) residues located on the surface of the molecule to give other amino acid residues. The invention further relates to methods of increasing the stability of an &#x3b1;-amylase to solvent-exerted hydrolysis, in particular at elevated temperatures or high pH, whereby at least one asparagine (N) or glutamine (Q) residue on the surface of the molecule is replaced with a different amino acid residue. The &#x3b1;-amylase variants obtained thereby exhibit better stability to influences of the solvent, increased processivity, and are suited for numerous industrial areas of use, in particular as active ingredients in detergents and cleansers.

Alpha-amylase variants having an elevated solvent stability, method for the production thereof and detergents and cleansers containing these alpha-amylase variants

Washing and cleaning agents containing benzophenone or benzole anilide derivatives containing carboxyl groups, which function as protease inhibitors and are suitable as enzyme stabilizers. Additional subjects are the use of such compounds as reversible inhibitors of a protease and consequently for a washing or cleaning agent formulation, and additional methods and uses relating thereto.

Benzophenone or benzoic acid anilide derivatives containing carboxyl groups as enzyme stabilizers

The invention relates to five or four novel genes and the gene products thereof fromand sufficiently similar genes and proteins which are involved in vivo in the formation of polyamino acids. The gene in question is ywsC, ywsC', ywtA, ywtB and ywtD or proteins coded thereby. The gene ywsC, ywsC&#x2032;, ywtA and ywtB can be used to improve biotechnological production methods by microorganisms, wherein they are functionally inactivated; the gene ywtD which codes for a peptide decomposing poly-gamma glutamate can, inversely, contribute to the improvement of biotechnological production methods by increased expression. Said genes can be used positively, preferably to result in a modification or decomposition of poly-gamma glutamate.
