常温降解玉米秸秆复合菌系及其 微生物多样性研究
The screening and diversity of a bacterial community capable of degrading corn straw at 30℃
摘要
Abstract
In order to promote corn stalk degrading under normal temperature, a bacterial community with high efficiency lignocellulose degrading, sampling from corn soil, was screened through continuous restricted cultivation and the degradation rate of cellulose as the main indicator. The optimum temperature and pH for lignocellulose degradation was 30 ℃ and 8, respectively. Under the condition above, the degrading rate of filter and corn straw was 66.5% and 66.1%respectively. Among the lignocellulose degradation rate of corn straw, the degradation rate of cellulose, hemicelluloses and lignin was 17.0%, 85.1%, 34.4%, respectively. The results of microbial diversity by high -throughput sequencing showed that the bacterial community was mainly composed of Pseudomonas(33.9%), Bacteroides (11.8%), Acidovorax (6.9%), Alcaligenes (3.8%), Butyrivibrio (1%) at the genus level. At the same time, the consortium was mainly composed of Alcallgenes-faecalis (2%), Microvirgula-aerodenitrificans (1.5%) at the species level. Bacterial community can efficiently decompose hemicelluloses, cellulose and other ingredients under normal temperature, and there is the potential for agricultural waste recycling.关键词
