摘要
农业废弃物中蕴含丰富的木质纤维素资源,对木质纤维素进行生物发酵可以有效利用可再生的生物质资源。木质素作为物理屏障,严重阻碍了纤维素的开发与利用。生物法降解木质素具有操作简便、环保的优点。该文综述了木质素降解过程中,解聚阶段和矿化阶段相关的酶类及其作用机制;总结了基于基因组学、转录组学以及蛋白质组学技术,深入挖掘微生物中的木质素降解酶系,为生物质资源的高效利用奠定了基础。
Agricultural waste contains abundant lignocellulose resources.Biological fermentation of lignocellulose can effectively utilize renewable biomass resources.As a physical barrier,lignin hinders the development and utilization of cellulose seriously.Biodegradation of lignin has the advantages of simple operation and environmental protection.This paper summarized the enzymes and their mechanism related to the depolymerization and mineralization stages in the process of lignin degradation.Based on genomics,transcriptomics and proteomics,the lignin degradation enzyme system in microorganisms were explored and summarized,which would lay the foundation for the efficient use of biomass resources.
