摘要
纤维素酶是一种重要的酶产品,主要由外切β-葡聚糖酶、内切β-葡聚糖酶和β-葡萄糖苷酶等组成,还有很高活力的木聚糖酶活力。这三类酶的协同作用,能将具有很强化学与生物抗性的天然纤维素大分子降解成简单的葡萄糖,这对于缓解当前世界所面临的能源、粮食、环境危机等问题具有重要的意义。本文就纤维素酶的微生物发酵方面的进展进行综述。
Cellulase is one important kind of enzyme product with high xylanase activity,which is mainly composed of endoglucanase,exo-glucanase and β-Glucosidase.The synergistic effect of these three enzymes can degrade cellulose,which has strong chemical and biological resistance,into simple glucose molecules,having significant meaning to solve some important problems in the world such as energy crisis,food crisis,environmental pollution,and so on.The progresses on microorganism fermentation are reviewed in this paper.
