摘要
作为农业副产品,农作物秸秆是一种重要的可再生资源。研究表明,农作物秸秆的主要成分是木质纤维素,而某些细菌和真菌生产的酶具有较好的生物化学性质,可用于木质纤维素的降解。本研究阐述了木质纤维素降解酶的种类和降解机理,综述了水稻秸秆、小麦秸秆和玉米秸秆的降解微生物种类。同时,本研究分析了当前单一菌株和复合菌系的在商业化利用上的不足,展望了未来的发展方向。本研究将为筛选新型优质木质纤维素降解菌和开发纤维素降解菌用于农业秸秆的资源化利用提供依据。
As the byproduct of agricultural production, crop straw is an important renewable resource. Previous studies have shown that the main component of crop straw is lignocellulose. Some microorganisms such as bacteria and fungi can produce certain enzymes that are capable to degrade lignocellulose. The present study summarized the types and degradation mechanisms of lignocellulose-degrading enzymes, and reviewed the reported microbial species which could degrade rice, wheat and corn straw. In addition, this study analyzed the shortcomings of the identified single microorganism strain and microbial complex for commercial application,and discussed the perspectives and directions of future research. The review will provide reference for screening novel high-quality lignocellulose degradation microorganisms and developing cellulose-degrading microorganisms for resource utilization of crop straw.
