    摘要: The present invention relates to methods of reducing the rate at which a cotton-containing fabric becomes harsh or of reducing the harshness of a cotton-containing fabric, comprising treating the cotton-containing fabric with a cellulase preparation obtained from a fungus, wherein the cellulase preparation comprises a substantially homogeneous endoglucanase component which: (a) has a pH optimum of about 7.5-10.0; (b) exhibits a CMC endoase activity of at least about 10 CMC-endoase units per mg of total protein; (c) exhibits a CAVU activity of at least about 50% at a pH of 7.0-12.0; and (d) has essentially no cellobiohydrolase activity; wherein at least about 50% by weight of the total cellulase content of the cellulase preparation is the endoglucanase component.

    摘要: The present invention relates to an enzyme exhibiting endo-beta-1,4-glucanase activity (EC 3.2.1.4), which is a) a polypeptide encoded by the DNA sequence of positions 1 to 2322 of SEQ ID NO: 1; b) a polypeptide produced by culturing a cell comprising the sequence of SEQ ID NO: 1 under conditions wherein the DNA sequence is expressed; c) an endo-beta-1,4-glucanase enzyme having a sequence of at least 97% identity to the amino acid sequence of position 1 to position 773 of SEQ ID NO: 2; and fragments thereof exhibiting endo-beta-1,4-glucanase activity, and d) a polypeptide having endo-beta-1,4-glucanase activity that is encoded by a polynucleotide that hybridizes with the nucleotide sequence shown in positions 1-2322 of SEQ ID NO: 1, is useful for detergent and textile applications.
