      随着石化资源日益枯竭和我国国情实际情况, 第二代生物质能源研发十分迫切。清洁高效降解自然界中第二大丰富的木质素资源亟待解决。相比物理和化学方法, 生物降解木质素因专一性强和环境友好等特点最具发展优势。本文简单综述了真菌和细菌微生物降解木质素的几种途径, 指出多组学(如蛋白组学、转录组学和代谢组学)技术是剖析微生物降解木质素分子机制的有力手段, 为生物降解木质素及其高效利用提供借鉴和参考。

英文摘要:

      With the dwindling supplies of oil based fuels and real situations in China, it is very urgent and crucial to develop the second generation biofuels from renewable biomass. Lignin ranks second only to cellulose filaments as the abundant and renewable source in nature. There are consideration interests in the utilization of lignin for production of bioenergy and renewable chemicals.Compared with chemical and physical methods, lignin biodegradation via microorganisms shows a promising trends with the significant characters of mild conditions, friendly environment and strong specificity. The review briefly presents lignin bio-breakdown pathway via fungi and bacterial microorganims, and the molecular mechnism of lignin bio-degradation is elucidated from the view of multi-omics approach, such as proteomics, transcriptome and metabonomics. It provides new insights on lignin biodegradation in microorganisms as well as its applications.
