纤维素降解细菌的筛选、生物学特性及降解效果
Isolation of cellulose-degrading bacteria and determination of their degradation activity
摘要
Abstract
Eight bacterial strains were isolated from soil in the east Qilian Mountains.Of these,four strains had a higher capacity for degradation of plant cellulose when cultured on a CMC-Na plate medium.The growth characteristics of the four strains were studied,and the optimum temperature range of the 4 active strains was 25-30℃,the optimum pH for growth was 5 -8,and the optimum sodium concentration was 4% to 5%.A strain designated X1-2 possessed the highest cellulose degradation ability.Based on morphology,gram stain re-action,and 16S rRNA phylogenetic comparison,this strain was identified as a member of the genus Bacillus (Bacillus sp.).It is a bacterium with strong plant cellulose degradation ability.关键词
