[Objective] The aim of the research was to supply theoretical basis for high efficient decomposition of cellulose.[Method] The strains that could decompose cellulose better were screened out from samples containing lignocellulose-decomposing microorganisms,such as forest defoliation soil,rotten straw and farmhouse compost.They were cultured solely and by mixed fermentation.[Result] Four strains that could decompose cellulose better were screened out finally,and they were judged as 3 strains of bacteria and ...
