一般描述

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。该产品针对纤维素乙醇研究进行了优化，可提高能效并防止浪费。更多信息请参阅《Biofiles》和《Enzymes for Alternative Energy Research》上的文章

应用

来自 曲霉 的纤维素酶。在 BBC（生物可吸收细菌纤维素）生物降解性分析期间，已用于将纤维寡糖降解为葡萄糖。这种酶还被用于光子相关光谱，以研究其对未过滤啤酒样品的影响。该光谱分析中评价的参数为悬浮颗粒的大小、流速和混浊稳定性。

生化/生理作用

纤维素酶是水解纤维素的酶，是由 β-1,4-糖苷键，与葡萄糖连接。内切-β-葡聚糖酶是纤维素酶复合体的主要组成酶之一。通过随机裂解分子内的糖残基来催化纤维素水解。外切-β-D-葡聚糖酶和 β-葡萄糖苷酶可协同作用将纤维素转化为葡萄糖，因此可用于工业规模。

Cellulases are enzymes that normally digest cellulose; however, some are known to play essential roles in cellulose biosynthesis. Although some endogenous cellulases of plants and cellulose-producing bacteria are reportedly involved in cellulose production, their functions in cellulose production are unknown.
