摘 要：摘 要：纤维素酶是糖苷水解酶的一种，它可以将纤维素物质水解成简单糖，进而发酵产生乙醇，从而解决农业、再生能源以及环境污染等问题。初期的研究主要集中在对微生物纤维素酶的研究，随着对纤维素酶研究的不断深入，“动物自身不含纤维素酶”这一传统理论被推翻，动物纤维素酶成为纤维素酶研究的热点。另外，生物化学、分子生物学以及基因工程等多种交叉学科的快速发展，获得适合工业化的高比活力的纤维素酶已指日可待。
Abstract: Abstract: Cellulase-one of the glycoside hydrolases- is responsible for conversion of renewable cellulosic biomass to simple sugars for fermentation to ethanol, which can settle the issue of agriculture, renewable energy and environmental pollution etc. Primeval studies were focused on the cellulase produced by microorganism. With the deep research of enzymatic hydrolysis of cellulase, the traditional view of “no cellulase in higher animals themselves”was pulled down and animal cellulase became the hotspot of cellulase study. In addition, the cellulase of higher specific activity for industrialization will be found as the rapid developments of many kinds of cross-subjects such as biochemistry, molecular biology and gene engineering etc.
Key words: cellulase; simple sugars; animal cellulase; industrialization; higher specific activity
