微生物酸性木聚糖酶及其应用的研究进展

摘要

Xylanase has attracted a great interest in recent years. Although some thermophiles and alkaliphiles xylanase have been invested, few reports involved the acidic xylanase. In this study, the strains capable of producing acidic xylanase, the critical fermentation factors affecting xlanase activity, as well as the purification and characteristics of the xylanase will be discussed. The special structure of the acidic xylanase and the potential industrial applications of these enzymes will also be presented.%木聚糖酶来源广泛，微生物酸性木聚糖酶作为木聚糖酶的一种，目前人们对其研究较少。文中介绍了产酸性木聚糖酶微生物菌株的来源，包括天然菌株和基因工程菌株；讨论了不同来源菌株发酵产酸性木聚糖酶的影响因素；总结了酸性木聚糖酶的纯化方法及纯酶性质并研究酶的结构特征与其耐酸性的关系，综述了酸性木聚糖酶在实际生产中的应用现状。
