Abstract:
Effects of multi-stage strengthening inoculation on bacterial community diversity were analyzed using PCR-DGGE method in municipal solid waste composting combined with Cluster analysis and changes of Shannon-Weaver index, and the changes of lignocellulose's degradation rate were also detected during the process. The results showed that Multi-stage inoculation of composting can improve the temperature of cooling and the secondary fermentation period. And the hemicellulose, cellulose and lignin degradation rate increased by 7.19%, 10.89% and 8.98% compared to general inoculation composting. The analysis of bacterial community diversity indicated that the diversity index of the two inoculation showed significant differences, the microbial inoculation could live well in the pile. It could avoid competition between different inoculated agents and competition between inoculated and indigenous microorganisms, and could improve bacterial community diversity during composting especially for maturity stage. It could speed up the composting process of stabilization.
