| Abstract: |
| The risk of environmental pollution caused by organic solid waste is increasing. Aerobic composting is a hot spot research on the resource utilization of organic solid waste. Microorganisms are the main decomposers that drive the biological transformation of organic solid waste and play an important role in aerobic composting. The study of microbial communities and the functional genes of material transformation in the process of organic solid waste resource treatment is of great significance in promoting organic matter mineralization, controlling nitrogen loss, reducing odor emission, and producing high-quality organic fertilizer products to achieve resource recycling. Microorganisms in aerobic compost are changed by a complex set of environmental factors. In recent years, with the development of molecular biology and highthroughput sequencing technology, many advances have been made in the study of microbial diversity and nitrogen-sulfur material transformation in aerobic composting. This paper mainly reviews the research progress of organic solid waste bioconversion based on aerobic composting technology, which mainly includes microbial diversity in aerobic composting, microbial community evolution mechanism, and the regulation mechanism of environmental factors on the evolution process of microbial community structure. These studies are expected to provide scientific basis for constructing bioconversion models, regulating the bioconversion process in aerobic composting and enhancing the efficient bioconversion technology of
organic solid waste. |
