纤维素酶是一种高效的生物催化剂,在纤维素类物质的利用方面发挥着重要作用.瘤胃来源的纤维素酶是一类能够分解瘤胃中纤维素类物质的酶或酶系,能将纤维素类物质分解成葡萄糖供给动物生长所需.对纤维素进行了概述,分析了瘤胃纤维素酶来源的细菌、真菌和其他微生物种类和分泌的纤维素酶以及瘤胃各类微生物对纤维素的降解过程,并对纤维素酶的种类和降解机理进行了阐述,为进一步研究瘤胃纤维素酶提供参考.
Cellulase is an efficient biocatalyst, plays an important role in the use of cellulose. The rumen cellulases are enzymes which are able to decompose the cellulose into glucose to offer ruminants for growing. In this paper, the cellulose was summarized, the bacteria, fungi and other microbes of rumen cellulase sources and secreted cellulases and various rumen microorganisms on degradation of cellulose were analyzed. Moreover, the degrading mechanism of cellulase and the classification of cellulases were described, to provide references for the further research on rumen cellulase.
