纤维素是自然界最丰富的多糖，其生物转化是由纤维素酶完成的。纤维素酶是由多种微生物合成的一种复合酶。许多不同的催化和非催化酶模块形成协同作用于其底物的纤维素酶，其中在一些厌氧细菌中，不同的纤维素酶被组织在一起形成多功能超分子复合物，称为纤维素酶体。对微生物纤维素酶的基础和应用研究产生了大量的科学知识，它们的作用模式及其巨大的工业应用。微生物纤维素酶用于食品、动物饲料、酿酒、葡萄酒、纺织、洗衣、造纸、纸浆和农业以及研究目的。对相对便宜的纤维素酶的不断增长的需求以及它们在多个工业部门中的提高的利用是对不同微生物纤维素酶的研究的主要驱动力。
Bioconversion of cellulose, nature's most abundant polysaccharide is accomplished by the enzyme cellulase. Cellulase, a complex of sequentially acting component enzymes are found to be synthesized by a variety of microbes. A number of different catalytic and non catalytic enzyme modules form the cellulase which synergistically acts on their substrates are reported, amongst which in some anaerobic bacteria different cellulases are organized together to form a multifunctional supramolecular complex known as cellulosome. Basic and applied research on microbial cellulases generated great scientific knowledge, their mode of action and their enormous industrial applications. Microbial cellulases are used in food, animal feed, brewery, wine, textile, laundry, paper, pulp and agriculture as well as in research purposes. The ever increasing demand for relatively non expensive cellulases and their enhanced utilization in multiple sectors of industries is the main driving force for research on different microbial cellulases.
