Improving composting efficiency by adding domestic garbage and analyzing related microbial mechanisms constitute the foundation for promoting the utilization of agricultural waste. The present study disentangled the composting efficiency and underlying fungal mechanisms by different domestic garbage amendments based on the industrial-scale aerobic composting. Results indicated that amendment of domestic garbage achieved significantly higher efficiency through elevated temperatures and germination indices, increased cellulose and hemicellulose transformation. Fungal community composition was observed to be distinct according to both the composting stage (PERMANOVA, F = 14.03, P<0.01) and treatment (PERMANOVA, F = 5.92, P<0.01). Functional profiles of the fungal community originated from the bioinformatic tool FUNGuild showed the activities of typical functional guilds symbiotrophic (r = -0.913) and pathogenic (r = -0.926) fungi was observed significantly negative relationships while saprotrophic (r = 0.947) was positive with composting maturity. Thus, high-efficiency composting could be considered as a process gradual decline of symbiotrophic and pathogenic fungi substituting by saprotrophic fungi. These putative functional guild were influenced by the key environmental conditions such as C/N, TOC and cellulose, thus contributing a significant dedication to the development of composting efficiency. The greenhouse pot experiments with maize seedlings exhibited that the composting end-product of domestic garbage amendment triggered significantly promoted the growth. Taken together, this study provides a further understanding how the functional ecological group of fungal community trigger enhanced composting performance.
