摘      要：There is an overlooked problem which increasing microbial abundance while reducing nitrogen loss during *** study investigated the viability of spent mushroom substrate(SMS)as conditioners in the aerobic composting of kitchen waste(KW)with cattle manure(CM).The variation of temperature,pH,C/N,organic matter,cellulose,hemicelluloses,germination index(GI),and microflora structure were explored to evaluate the potential in accelerating maturity and nitrogen fixation by SMS *** results showed that the addition of SMS accelerated the heating rate,prolonged the high temperature time,and decreased organic matter,hemicellulose,and cellulose by 17.49%,23.61%,and 18.62%,*** GI reached 105.86%with SMS addition,while 74.17%was found in control treatment after *** changed the microbial community composition and increased the species ***,Clostridium XI and Azomonas were dominant bacteria,which increased the retention of nitrogen,promoted organic matter degradation and reduce compost *** study can provide a feasible strategy for nitrogen fixation in the field of organic waste recycling.
