ABSTRACT
This study aims to screen high-degradability strains and develop a novel microbial agent for efficient food waste degradation. The effects of the novel microbial agent on organic matter degradation, enzyme activity, and bacterial succession during the in-situ reduction of food waste were evaluated and compared with other two microbial agents previously developed. Results showed that the novel agent containing four Bacillus strains received maximum organic degradation rates, volatile solid removal (46.91%) and total mass reduction (76.16%). Pyrosequencing analysis revealed that there was a significant difference in the microbial community structure of the matrix among the three biodegradation systems, and the novel agent greatly improved the stability of in-situ reduction process that Bacillus was the dominant genus (>98%) since day 4. These results indicated that the inoculant containing only Bacillus was more stable and cost-effective in FW in-situ reduction.
