This study aimed to reveal mechanisms of nitrogen changes in a mixed compost diseased pig carcasses and sawdust after adding exogenous microbial agents. It was found that agents significantly increased the content various types germination index plants. Microbial dominance phyla correlated with indicators physicochemical properties copy number nitrogen-functional genes, simultaneous fixation, nitrification, denitrification, ammonification, glutamate synthesis during composting. At end composting, TKN, NH4+-N, NO3−-N contents were by 1.914–3.082 mg/g, 0.047–0.42 0.247–0.303 respectively, experimental groups compared control group. Proteobacteria, Bacteroidetes, Firmicutes, Actinobacteria, Planctomycetes five predominant phyla, while Sphingobacterium, Paenalcaligenes two special genera this experiment. After inoculation agents, levels nitrate positively (p < 0.05) glnA gene related 0.01) Planctomycetes, amoA, GDH2, GLUD1-2 genes Paenalcaligenes. The combined analysis has shown amoA 0.001) such as nxrA, GDH2 GLUD1-2, well temperature, organic nitrogen, correlation negative nirB nirS. Inoculation can prolong high-temperature period, which extended 5, 6, 5 days each group, roles also be changed. Meanwhile, we addition could promote growth alteration microorganisms, regulated stability symbiosis transformation process.
