摘要曲霉菌通过发酵、传染病和食品霉菌毒素污染与人类密切相关。这个属的成员产生各种酶来降解植物多糖，包括淀粉、纤维素、木聚糖和木葡聚糖。本文主要综述了曲霉菌中利用糖苷水解酶降解木葡聚糖的机制，如木葡聚糖酶、产异源葡聚糖的低聚木葡聚糖水解酶和α-木糖苷酶。一些木葡聚糖降解相关的糖苷水解酶在该属中保存良好；然而，其他酶不是。这些糖苷水解酶的协同作用对曲霉菌的木葡聚糖降解至关重要。•综述了曲霉类木葡聚糖降解相关酶的研究进展。•每种曲霉都有不同的糖苷水解酶。•概述了m.o ryzae木聚糖降解的机制。
AbstractAspergillusspecies are closely associated with humanity through fermentation, infectious disease, and mycotoxin contamination of food. Members of this genus produce various enzymes to degrade plant polysaccharides, including starch, cellulose, xylan, and xyloglucan. This review focus on the machinery of the xyloglucan degradation using glycoside hydrolases, such as xyloglucanases, isoprimeverose-producing oligoxyloglucan hydrolases, and α-xylosidases, inAspergillusspecies. Some xyloglucan degradation-related glycoside hydrolases are well conserved in this genus; however, other enzymes are not. Cooperative actions of these glycoside hydrolases are crucial for xyloglucan degradation inAspergillusspecies.Key points•Xyloglucan degradation-related enzymes of Aspergillus species are reviewed.•Each Aspergillus species possesses a different set of glycoside hydrolases.•The machinery of xyloglucan degradation of A. oryzae is overviewed.
