摘　　要：木聚糖酶(EC3.2.1.8)可催化木聚糖的水解,可应用于食品、酿酒、造纸、饲料、纺织等行业。由于许多工业应用的单元操作都是在高温下进行的,寻求耐热木聚糖酶是非常重要的。该文介绍了耐热木聚糖酶菌的筛选、基因工程和分离纯化的研究及应用。Xylanase(EC3.2.1.8)could catalyze the hydrolysis of xylan.The application of xylanase is extremely extensive,and widely used in food,paper,feed,textile,and many other industries.Many kinds of processes in a multitude of possible applications of xylanases are performed at high temperatures,thus it is highly desirable to search for thermostable xylanases.In this paper,the screening,transgenic technology and purification of thermostable xylanases were introduced in detail.

关 键 词：耐热木聚糖酶 基因工程 纯化
