木质纤维素降解菌的筛选、鉴定及酶学性质
Screening and Identification of Lignocellulose Degrading Bacteria and Study in Its Enzymatic Properties
摘要
Abstract
To provide experimental data and theoretical guidance for the high-value utilization of lignocellulose,strains with high decomposition efficiency for lignocellulose were screened and their enzymatic properties were studied.In this study,a strain of Bacillus subtilis was screened from Guangdong Maoming Lutiankuang Ecology Park.The xylanase and endoglucanase produced by the strain had optimum temperatures of 50℃and 60℃,and optimum pH of 7.0 and 6.0,respectively.while xylanase maintained good pH stability under medium-alkaline conditions.Metal ions and chemical reagents have varying degrees of inhibitory effects on xylanase,while Cu2+and SDS have a slight promoting effect on endoglucanase.The excellent performance of lignocellulose degrading enzymes secreted by Bacillus altitudinis strain OU9 provides enormous potential value for the efficient green degradation and exploitation as well as application of lignocellulose.关键词
