木质素的微生物降解机制

研究微生物降解木质素的反应机理,可以从根本上解释微生物或酶对木质素的作用过程,对提高木质素降解效率,治理环境污染等具有非常重要的意义。从木质素结构的差异出发,总结了近年来研究木质素微生物降解机制所采用的主要模型化合物、研究方法,概述了微生物对木质素的三大作用机理:侧链氧化、去甲基化和芳香环断裂,以及参与这三个反应的主要微生物。

Lignin Degradation Mechanism by Microbes

Study on lignin degradation reaction mechanism by microbes could fundamentally explain the reaction process of lignin by microbes or enzymes,therefore,it has very important significance to improve the efficiency of lig- nin degradation and to prevent and control environment pollution.Based on the differences of lignin structures,this ar- ticle summarizes the main model compounds and research methods used in recent years studies on lignin degradation by microbes,and outlines three reaction mechanisms of microbes on lignin:side chain oxidation,demethylation,and aromatic ring cleavage,and main microbes that take part in these three reactions.
