The screening method of degrading rice-straw was studied.The degradation rate of cellulose hemicellulose and degradation rate of straw were used as index and new concept of screening strains suitable for degrading rice-straw was proposed.Rice straw powder agar plate was used in preliminary screening method.Rice straw powder pretreated with 1 % NaOH was used as fermentation culture medium in the replicated screen.One strain that could degrade rice straw was obtained.Fermentation characteristics and degradati...
