Three bacterial strains had been screened from soil,straw and cattle manure by various screening criterions which had capacity and potential of ligocellulose degradation,temperature-rising and deodorization.According to the morphological,cultural feature,physiological and biochemical features and 16S rDNA sequencing,the three bacterial strains were identified as Bacillus sp..The experimental results of compost functional verification showed that which addition with these three bacterial strains,the degradation rates of cellulose,hemicelloluse and lignin in compost were 31.31%,19.57% and 14.33% higher than those of control,respectively,and the germination rate was 93.3% which was higher than control by 36.6%.So these three bacterial strains had potential of promoting ligocellulose degradation and improving maturity in cattle manure compost.It was predicted that Bacillus sp.X9，Bacillus sp.L1 and Bacillus sp.L8 had promising prospects of being applied in improving the resource utilization of cattle manure in larger scale or utilized in other livestock and poultry manure compost.
