Abstract: An actinomycete strain C-5, capable of degradating rice straw effectively, was isolated from soil which had been under the stock pile for several years, using methods of cellulose culture-medium selection and Congo red dyeing. The isolated strain was identified as Streptomyces sp. according to its phenotypic features and 16S rRNA phylogenetic analysis. This strain has enzymatic activities of cellulase, laccase, peroxidase, xylanase and pectinase simultaneously. After 30d of inoculating with C-5, the dry weigh of rice straw was decreased by 72%. C-5 could decompose rice straw effectively and had good application prospects in improving utilization of the rice straw resource.

Key words: actinomycete strain for rice-straw degradation, streptomycete, 16S rRNA sequence, sequencing
