一株纤维素降解菌的筛选与鉴定
Screening and Identification of Cellulose Degradation Bacteria
摘要
Abstract
12 cellulose-degrading bacterias were enriched and isolated from the leaves of the humus layer covering the soil and a high-degrading bacteria （ X10 ） was selected from these. The optimal culture conditions of the bacteria were as follows ： took the culture medium containing glucose＋micrlte cellulose （1：1）as carbon sources, peptone＋beef（ 1：1 ）as nitrogen sources, pH 7.5, under 30℃, with the culture time was 40 b, the cellulose-degrading enzyme activity was up to 57.44 U.Through its 16s rRNA sequencing,the homology of bacteria and Microbacterium oxydans were 99%.The selection of cellulose-degrading bacteria provided a new source of bacteria for the egiciem production of cellulase.关键词
