Claims23
A method for washing fabrics composed of proteinogenic fibers comprising contacting said fabric with a composition comprised of at least one surfactant and a proteolytically active amount of a protease selected from the group consisting of F49 variant having S3T+V4I+A188P+V193M+V199I+L211D mutations, F46 variant having S3T+V4I+S154E+A188P+V193M+V199I, and combinations thereof having a keratinase/caseinase activity ratio of less than about 0.80.
A method for washing fabrics composed of proteinogenic fibers comprising contacting said fabric with a proteolytically active amount of a protease selected from the group consisting of F49 variant having S3T+V4I+A188P+V193M+V199I+L211D mutations, F46 variant having S3T+V4I+S154E+A188+V193M+V199I, and combinations thereof having a keratinase/caseinase activity ratio of less than about 0.80 and an anionic surfactant selected from the group consisting of a fatty alkyl sulfate, a fatty alkyl ether sulfate, a sulfofatty acid ester, a sulfofatty acid disalt, and combinations thereof.
A method for washing fabrics composed of proteinogenic fibers comprising contacting said fabric with a detergent composition comprising from about 20% to about 55% by weight of an inorganic builder;
- up to about 15% by weight of a water-soluble organic builder;
- from about 2.5% to about 20% by weight of an anionic surfactant;
- from about 1% to about 20% by weight of a nonionic surfactant;
- up to about 25% by weight of a bleaching agent;
- up to about 8% by weight of a bleach activator;
- up to about 20% by weight of an inorganic salt;
- from about 0.4% to about 1.2% by weight of a lipase, cutinase, amylase, cellulase, pullulanase, oxidase or peroxidase and a proteolytically active amount of a protease selected from the group consisting F49 variant having S3T+V4I+A188+V193M+V199I+L211D mutations, F46 variant having S3T+V4I+S154E+A188P+V193M+V199I, and combinations thereof having a keratinase/caseinase activity ratio of less than about 0.80.
A method for washing fabrics composed of proteinogenic fibers comprising contacting said fabric with a detergent composition comprising from about 20% to about 55% by weight of an inorganic builder;
- up to about 15% by weight of a water-soluble organic builder;
- up to about 15% by weight of an anionic surfactant;
- from about 4% to about 24% by weight of a nonionic surfactant;
- up to about 65% by weight of an inorganic salt;
- and a proteolytically active amount of a protease selected from the group consisting of F49 variant having S3T+V4I+A188P+V193M+V199I+L211D mutations, F46 variant having S3T+V4I+S154E+A188P+V193M+V199I, and combinations thereof having a keratinase/caseinase activity ratio of less than about 0.80.
A method for removing stains from cloth which comprises contacting a cloth having both blood and egg stains with a composition comprising at least one surfactant and a proteolytically active amount of first and second mutant proteases wherein in said first mutant protease at least one of the amino acid residues at positions 99 and 154 are different from those in Bacillus lentus DSM 5483 and wherein in said second mutant protease at least the amino acid residue at position 211 is different from that in Bacillus lentus DSM 5483.
A method for removing stains from cloth which comprises contacting a cloth having both blood and egg stains with a composition comprising at least one surfactant and a proteolytically active amount of first and second mutant proteases wherein each of said protease has an amino acid subsitution selected from the group consisting of R99G, R99A, R99S, S154D, S154E, L221D, L211E, and a combination thereof.
