| 摘要 | [Objectives]To isolate and identify characteristics of the cellulose-degrading bacteria.[Methods]In view of the poor effect of crop straw composting,the strains which can degrade cellulose were isolated and purified from the soil piled with rice straw,and the strains A2 and A5 with high efficiency of cellulose degradation were finally screened through the transparent circle,cellulase activity and filter paper disintegration experiments.[Results]It was confirmed that the strains A2 and A5 could degrade cellulose well.The results of 16s rDNA showed that A2 was Pseudoxanthomonas mexicana and A5 was Bacillus cibi.[Conclusions]The results of this study are expected to provide high-quality strain resources for the degradation of cellulose in straw,and have important application value for improving the efficiency of straw composting. |
