Abstract

Abstract:

Microorganisms are the main drivers of the composting process and their dynamics changes all the time,and then influence the composting process and the quality of compost. Many studies demonstrated that,exogenous inoculants may promote the composting process,accelerate the decomposition of organic matter and composting maturity,reduce antibiotics and other harmful substances. Feature of kitchen wastes,such as high oil,high salt,high moisture,easy acidification,etc.,affects the microbial activities of these processes. Combined with advanced molecular biology techniques,enriching,and domesticating specific-condition samples,and then using selective culture which was aiming to attain microbes with different functions for decomposing raw materials. Based on these selected microbes,they could promote the composting process with kitchen wastes and overcome the problems during composting when using them. This paper was mainly described the dynamics of microorganisms in composting process with kitchen wastes,explored the influence of applying these different types and functions of microbial inoculants during composting processes,in order that providing technical support and theoretical reference for the development of kitchen waste resource utilization and biological enhancement.

Key words: exogenous microbial inoculum in composting, kitchen waste, aerobic composting
