文摘

Fed-batch composting was achieved with feeding ratios of 5% and 10% but not 15%. The thermophilic conditions were obtained due to bacterial self-heating. The compost failure at the 15% treatment was mainly ascribed to excessive moisture. Firmicutes et al. were the dominant degraders in the food waste compost. Temperature was the key environmental factor for community succession.
