筛选微生物降解木质纤维素的研究进展

木质纤维素资源是自然界中含量丰富的可再生资源,利用微生物降解木质纤维素是一种重要的策略。在综合国内外对木质纤维素降解微生物的筛选方法和研究策略的基础上,从单一菌株、复合微生物菌系和组学技术三个方面对筛选微生物降解木质纤维素进行了总结和分析,阐述了各个策略的优势特点和应用价值,即单一菌株易于培养但降解能力较低,复合菌系降解能力强但传代稳定性较差,组学技术能够更好的解释微生物降解木质纤维素的机理,为筛选木质纤维素降解微生物提供一定的指导。同时提出使用合成生物学的策略进行相应微生物的筛选,旨在为筛选高效降解木质纤维素的微生物提供一定的参考。

Research Progress on Degradation of Lignocellulosic Biomass by Screening Microorganisms

Lignocellulosic resources are abundant renewable resources in nature, and the degradation of lignocellulosic by microorganisms is an important strategy. Based on the study of screening methods and research strategies of lignocellulosic degradation microorganisms all around the world, the advantages, characteristics and application value of lignocellulose degradation by microorganism are summarized and analyzed from single strain, microbial consortium and omics technology: single strain is easy to cultivate but lack of strong degradation ability. Microbial consortium is good at lignocellulose degradation but has poor subculture stability. The omics technology can better explain the mechanism of microbial degradation of lignocellulose, and provide good guidance for screening lignocellulose degradation microorganisms. The strategy of synthetic biology is proposed for screening the Lignocellulose degrading microorganisms, in order to provide some reference for screening the microorganisms which can degrade lignocellulose efficiently.
