摘要: 秸秆的成分主要有纤维素、半纤维素和木质素等,降解秸秆的微生物包括细菌、放线菌和真菌。低温秸秆降解微生物的选育方法有直接从自然界中筛选、诱变育种、原生质体融合育种、基因工程育种等。目前,筛选获得的低温秸秆降解菌株的数量有限,降解秸秆的能力不高,低温条件下菌株的降解机理都需要进一步的研究。综述了低温条件下秸秆降解微生物菌剂的研究进展。

Abstract: The components of straw are cellulose, hemicellulose and lignin. Straw degradation microorganisms including bacteria, actinomyces and fungi. The methods of breeding straw degradation microorganisms include screening from nature, mutation breeding, protoplast fusion breeding, gene engineering breeding and so on. At present, the straw degradation strains under low temperature can be screened few in number, the ability of straw degradation is confined, further study need to be done on the mechanism of low temperature straw degradation. Microbiological agent of straw degradation under low temperature was summarized.
