Some microorganism strainswhich decompose cellulose or lignin were isolated from rotten bamboo materialwhich were collected from Phyllostachys edulis forest. 16 strains including 8 fungi strains, 5 bacteria strains and 3actinomycetes strains were screened using qualitative and quantitative methods. Bamboo material decomposingability of those strainswere tested through solid fermentation. Results showed that strain F2 and F10 were the mostefficient decomposer. After 15 days of incubation, strain F2 could decompose 23. 96% of bamboo cellulose and16192% of bamboo lignin and strain F10 could decompose 24. 31% of bamboo cellulose and 23. 15% of bamboolignin. In test condition, the cellulose degradation rates of the two strains were both higher than that of theTrichoderm a viride YJ-3, and their lignin degradation rates were both higher than that of the Phanerochaetechrysosporium ME-446.
