Twenty-nine facultative anaerobic cellulose-degrading bacteria were isolated from soil, rumen fluid, rumen residues and diet of dairy cow.Based on 16SrDNA analysis by BLAST algorithm method,the results showed that most of the strains were Bacillus genera, and six of the 29 strains were bigger than 10 mm of diameter of clear zones. For them, two strains were isolated from rumen fluid (L5 and L7) and other two were isolated from rumen residue (N5 and N9), while others were isolated from soil (T1) and diet (S6), respectively. Strains from rumen fluid and residue had higher activities of FPCase and CMCase, but lower β-glucosidases.
