【摘要】 为探索高效纤维素降解菌在农业领域应用研究的新思路，通过检索分析近年来纤维素降解菌筛选及产酶优化相关研究的文献，从菌株种类、产酶条件优化研究、复合菌（群）构建和菌（群）在农业应用等4个方面进行了总结，归纳了不同种类菌株筛选策略和优势特点，分析了纤维素降解菌产酶条件优化的原料种类及菌株的各异性，阐述了复合菌（群）构建的必要性及其重要意义，综合概括了纤维素降解菌（群）在生物肥料、农作物废弃物、生物能源三个方面的应用概况。提出当前研究在单一菌体所产纤维素酶种类单一、复合菌（群）产酶条件优化等方面存在不足，提出加强高效纤维素降解菌筛选、利用分子生物学技术构建纤维素降解菌的基因库以及降解机制研究等建议，以期为提高纤维素降解菌筛选效率，减少农业废弃物资源浪费，促进农业快速发展和资源循环利用提供理论支撑。更多还原

【Abstract】 To explore new approaches for the application of efficient cellulose-degrading microorganisms in agriculture, this study conducted a literature review and analysison the screening of cellulose degrading bacteria and the optimization of enzyme production in recent years, summarizing and analyzing four key aspects: strain types, enzyme production condition optimization, construction of composite microbial communities, and applications of these microbial communities in agriculture. The study outlines different screening strategies and advantages of various strains, analyzes the raw material types and strain specificity for optimizing cellulose-degrading enzyme production conditions, and discusses the necessity and significance of constructing composite microbial communities. Additionally, it provides a comprehensive overview of the applications of cellulose-degrading microorganisms(or communities) in three areas: biofertilizers, crop residue utilization, and bioenergy. The study identifies current limitations, such as the limited variety of cellulases produced by single strains and the need for optimized enzyme production conditions in composite microbial communities. To address these issues, the study proposes focusing on enhancing the screening of efficient cellulose-degrading microorganisms, utilizing molecular biology techniques to construct gene banks for cellulose-degrading microorganisms, and studying their degradation mechanisms. These efforts aim to improve the efficiency of screening for cellulose-degrading microorganisms, reduce the waste of agricultural resources,and promote rapid agricultural development and resource recycling.更多还原
