The Biological and Chemical Mechanism for Quick Decomposition of Rice Straw by Straw Rot Agent

The impacts of adding straw rot agent at different periods on activities of cellulase,hemicellulase and phenol oxidase in rice straw were determined by the method that used to determine the activity of enzyme.The results showed that adding straw rot agent had significant impact on increasing the activities of cellulase,hemicellulase and phenol oxidase.The results of isolation of pure culture indicated that adding straw rot agent can increase the amount of bacteria,fungi and actinomycetes in different growing stages.Meanwhile,through quantitative analysis procedures found that the degradation rate of cellulose,hemicellulose and lignin increased after adding straw rot agent.
