Abstract:

Each of the total 13 strains of bacteria was isolated based on the characteristics of municipal waste and excrement, which include 6 strains of bacterium, 4 strains of streptomyces and 3 strains of actinomycetes; all of these were appropriate for aerobic composting. The Efficient Microbial Community (EMC) was constructed by these strains combination at certain ratios. A series of experiments were performed to investigate the effect of feeding EMC on temperature, microbial biomass, C/N, ammonia nitrogen and seed germination index during aerobic composting process. The results indicate that, compared to the natural process, the composting period therefore was shortened from 20 to 13 days in relation to the improvement of organic waste degradation and high microbial biomass. In addition, EMC could prompt the growth of tall fescue seeds, and the waste reached complete maturity at the end of composting, which was suitable for agriculture use as an organic fertilizer.
