Abstract: Mixed cellulose degraders were screened from the cattle manure and stalks of cassava composting in the laboratory,further isolation was done through alternative plating method,and a strain named CE5 was obtained,which could effectively degrade cellulose. The strain CE5 was enriched in liquid medium,and inoculated in the composting materials to assess the influence of the addition of CE5 on composting process. The results showed that adding CE5 had a higher temperature than controlling samples,at the end of composting,the germination index,total N and effective N of experimental samples were higher than control samples,while C /N was lower,WSC and organic matter had no significant difference,indicating that biodegradation of the experimental group was more than controlling samples. Also,SEM analysis revealed that stalks of cassava of experimental samples were better degraded than the controlling group. Hence,adding CE5 can enhance the quality of composts.
