應用
来自Sigma的纤维素酶已被用于研究其几种可能的底物、纤维素、Avicel PH-101和滤纸,在动物和禽类消化道的单胃消化过程中保护酶活性的能力。
该酶还被批准作为辅助蛤虾加工的二级直接食品添加剂。
生化/生理作用
来自 黑曲霉(Aspergillus niger) 的纤维素酶可催化纤维素、地衣素、大麦葡聚糖和纤维低聚糖中的内切-1,4-β-D-糖苷键水解为纤维己糖。 其不会切割纤维二糖或 p-硝基苯基-β-D-葡萄糖苷。 该酶还可通过水解木糖基丝氨酸键从核心肽中切割完整的糖胺聚糖。
單位定義
在pH 5.0,37℃条件下,一个单位可在1小时内从纤维素中释放出1.0μmole的葡萄糖(孵育时间为2小时)。

Biotechnology for biofuels, 13, 124-124 (2020-07-21)
The current production of bioethanol based on lignocellulosic biomass (LCB) highly depends on thermostable enzymes and extremophiles owing to less risk of contamination. Thermophilic bacterial cellulases are preferred over fungi due to their higher growth rate, presence of complex multi-enzymes

A major challenge in converting lignocellulose to biofuel is overcoming the resistance of the biomass structure. Herein, sequential dilute acid-alkali/aqueous ammonia treatment was evaluated to enhance enzymatic hydrolysis of poplar biomass by removing hemicellulose first and then removing lignin with
