摘要
木聚糖是除纤维素之后,自然界中第二丰富的可再生资源,结构十分复杂,需要木聚糖降解酶系的协同作用才能将其完全水解。在木聚糖降解酶系中,β-1,4-内切木聚糖酶是使木聚糖完全水解最关键的酶,主要来源于细菌、真菌、放线菌等微生物,应用领域广,主要表现在食品、饲料、制浆造纸等行业。该文综述了微生物β-1,4-内切木聚糖酶的来源、选育、酶学性质、分类、分子结构、分子生物学及应用等研究进展。
Xylan is the second largest recyclable natural resource after cellulose with complex structure. Complete enzymatic hydrolysis of xylan re- quires the cooperative action of a series of enzymes. Among xylan degradation enzymes, endo-1,4-β-xylanase is the key enzyme to complete hydrolysis of xylan, and it mostly come from bacteria, fungi, actinomycetes and so on. Xylanase has a wide range of potential biotechnological applications, such as food, feed, pulp and bleaching processes. The source, breeding, enzymatic property, classification, molecular structure, molecular biology and application of endo-1,4-β-xylanase was reviewed in this paper.
