Abstract：To investigate the efect ofcellulose degrading bacteria on fermentation quality and the celllase content，Cellulomonas iranensis （CE）and Bacillus safensis （BS），which have strong cellulose-degrading capability，were used to add in the rice straw sliage.On day 14 and 3O，we determined the fermentation quality and cellulase content.After14 days of anaerobic fermentation，the CE could significantly reduce the pH value， ammonia nitrogen content and increase crude protein content of the rice straw （ P<0.05 .Compared with the control group，the addition of BS and CE significantly reduced the pH value ?P<0.05） ，the crude fiber and hemicelulose content of rice straw.After 3O days of fermentation，compared with the control group，The BS could significantly reduce the dry matter，mold number and propionic acid content of rice straw （ （P<0.05） ，and significantly increase the crude protein content of straw （ ?P<0.05 .CE could significantly reduce the pH ，dry matter，ammonia nitrogen content and mold number of rice straw （ P<0.05 ）.The contents of crude fiber，neutral detergent fiber，acid detergent fiber and hemicelllose in rice straw were significantly reduced by the addition of BS and CE（ ?<0.05） . The inoculation of cellulose-degrading bacteria could play a certain role in improving the fermentation quality of straw and reducing the celulose content in rice straw.And CE showed better effect.
