英文摘要	Nitrogen loss is the main problem in compost and controlling it is the key to the recovery and utilization of composted materials. This study systematically investigated the effect of nitrogen retaining microbial agent (NRMA) on nitrogen retention and the promotion of decay during manure composting and tested its effect on nitrogen conversion and bacterial community structure. During composting, various parameters were dynamically evaluated, including nitrogen loss and transformation, compost maturity and nutrient, microorganism population and bacteria community variation. Results showed that the inoculation of NRMA significantly reduced ammonia loss by 58.8% with 15 days shorter compost cycle. At the end of the composting, the total nitrogen (TN) and nitrate content of the experimental group were 23.3 g kg-1 and 4.5 g kg-1, 22.6% (p < 0.05) and 9.6% (p < 0.05) higher than those of the control group (19 g kg(-1) and 4.1 g kg(-1)), respectively. In contrast, the ammonia emission and ammonium nitrogen in the experimental group (4.9 g and 1.4 g kg(-1)) were significant lower than those (11.9 g and 1.8 g kg(-1)) in the control group (p < 0.05). Nitrogen-transforming bacteria such as Paucisalibacillus, Sporosarcina, Sphingobacterium, and Oceanobacillus displayed obvious advantages at high temperatures, while Longispora and Luteivirga demonstrated clear benefits at the end of the compost. The mechanism of nitrogen loss reduction was proposed, which was regulated by the specific microorganisms in the compost, especially the strains from the NRMA. The strategy of addition NRMA shows great potential for industrial applications of manure compost, which could provide a novel alternative for the recovery of nitrogen resources from animal husbandry.
