    • Cellulases selected from the group consisting of Family 7 cellulases and variants of these cellulases comprising a core and optionally a C-terminal link consisting of 10 amino acids at the most, especially cellulases having tryptophan, tyrosine or phenylalanine in position 55 relative to the sequence alignment of Figure 5 and/or cellulases having a substrate binding cleft of a depth of at least 12 ANGSTROM , exhibit enhanced enzyme activity in the alkaline pH range while exerting a moderate cellulolytic action on the cellulosic substrate and are, for example, useful in detergent compositions, especially for soil removal or colour clarification or preventing backstaining; in fabric softeners; for bio-polishing of textiles; for drainage improvement of paper pulp; for plant degradation. Cellulases from Humicola insolens, Fusarium oxysporum, Trichoderma reesei and Myceliophthora thermophile are referred to.
    • 选自由7族纤维素酶和这些纤维素酶变体组成的组的纤维素酶,其包含核心和任选的由最多10个氨基酸组成的C-末端连接物,特别是相对于序列比对在位置55具有色氨酸,酪氨酸或苯丙氨酸的纤维素酶 和/或具有至少12 ANGSTROM深度的底物结合裂缝的纤维素酶在碱性pH范围内表现出增强的酶活性,同时在纤维素基质上施加中等的纤维素分解作用,并且例如可用于洗涤剂组合物 ,特别是去除污垢或进行颜色澄清或防止背染; 织物柔软剂; 用于纺织品的生物抛光; 用于纸浆排水改良; 用于植物降解。 来自Humicola insolens,尖孢镰刀菌,里氏木霉和嗜热丝孢杆菌的纤维素酶被参考。
