由Yakult制造

应用

纤维素酶是可将纤维素水解成葡萄糖的酶。纤维素酶已被用于洗涤剂、制药、烘焙和酶生产行业中职业性哮喘的发展研究中。 将纤维素酶添加至洗涤剂中可改善清洁性能。 来自Sigma的纤维素酶已用于将纤维寡糖降解为葡萄糖，同时对生物可吸收细菌纤维素（BBC）的生物降解性进行了研究。

生化/生理作用

纤维素酶由白蚁的肠鞭毛虫产生，其对于宿主白蚁的纤维素消化至关重要 。纤维素酶具有不同的微生物来源，因此具有不同的蛋白质序列 。

单位定义

在pH 5.0，37℃条件下，一个单位在一个小时内可从纤维素中释放1.0 μmole葡萄糖（孵育时间为2小时）。

制备说明

在浓度为3mg/mL的0.15聚六亚甲基双胍（PHMB）存在下，溶于无菌去离子（DI）水中。
