Application

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。

Biochem/physiol Actions

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

Preparation Note

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。

Other Notes

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)。

Biofilm formation by Listeria monocytogenes is generally associated with its persistence in the food-processing environment. Serotype 1/2a strains make up more than 50% of the total isolates recovered from food and the environment, while serotype 4b strains are most often

Phototrophic biofilms are key to nutrient cycling in natural environments and bioremediation technologies, but few studies describe biofilm formation by pure (axenic) cultures of a phototrophic microbe. The cyanobacterium Synechocystis sp. strain PCC 6803 (here Synechocystis) is a model microorganism

The intestinal flagellates of termites produce cellulases that contribute to cellulose digestion of their host termites. However, 75% of all termite species do not harbour the cellulolytic flagellates; the endogenous cellulase secreted from the midgut tissue has been considered a
