微生物单宁酸酶的研究进展与展望

Advance and perspect of microbial tannase

由于单宁酸酶催化机制复杂且商品化需求日益增加,在过去的几年里,已成为了许多专家学者研究的热点。单宁酸酶可催化发生在植物中的非微生物反应体系中的复合单宁酸水解反应。从酶的分子结构、催化作用、微生物生产的条件优化及酶的纯化、酶的主要性状等方面对单宁酸酶的研究历程进行了一一回顾,并对单宁酸酶的潜在效应及生物降解方面的研究进行了展望。

In the last years, tannase has been the subject of a lot of studies due to its commercial importance and complexity as catalytic molecule. Tannases are capable of hydrolyzing complex tannins,which represent the main chemical group of natural anti-microbials occurring in the plants. The ＂advances＂ trace the route from the general molecular,catalytic ,and functional information obtained under close to optimal conditions for microbial production through purification, description of the enzyme properties, and commercial applications to the ＂ perspectives＂ including expression studies, regulation, and potential uses;aspects related to the progress in our understanding of tannin biodegradation were also included.
