一般說明
如果生产过程中使用非致病性和非产毒菌株，同时利用目前良好的生产实践，FDA将从 A.niger 中获得的纤维素酶确认为GRAS（一般认为安全）。
我们致力于为您提供更环保的替代产品，以符合“绿色化学的12项原则”的一项或多项原则要求。该产品已用作替代能源的酶。欲了解更多，请参阅替代能源的酶研究。
纤维素酶属于糖苷水解酶类，由各种纤维素分解微生物分泌。

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）。
