一般描述
纤维素酶是糖苷水解酶家族的成员之一，由多种纤维素分解菌产生。
应用
从黑曲霉（ Aspergillus niger ）中提取的纤维素酶，可用于：
- 制备标准品溶液，确定绝对纤维素酶水平
- 在磷酸盐-柠檬酸缓冲液中进行活性测定
- 非淀粉多糖降解酶混合物，用于脱脂米糠的体外水解及研究提高家禽饲料营养价值的方法
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。
单位定义
1 U 相当的酶量，可在 pH 5.0、37°C 条件下，每分钟从羧甲基纤维素中释放 1 μmol 的葡萄糖。

Microplastic particles (MP) are efficiently retained in wastewater treatment plants and enriched in sewage sludge. For monitoring MP contents in wastewater systems, sewage sludge is thus well suited, but also requires an isolation of MP from the sludge matrix, as

Three species of the β-Proteobacterial genus Herbaspirillum are able to fix nitrogen in endophytic associations with such important agricultural crops as maize, rice, sorghum, sugar-cane and wheat. In addition, Herbaspirillum rubrisubalbicans causes the mottled-stripe disease in susceptible sugar-cane cultivars as
