In this study, two isolated strains of nitrogen-fixing bacteria, NF1 (Bacillus subtilis) and NF2 (Azotobacter chroococcum), were added to cow dung compost in individual (NF1, NF2) mixing (NF3; with a ratio 1:1). The results revealed that the total nitrogen levels NF1, NF3 treatments increased by 44.71%, 38.43% 55.35%, respectively, when compared Control (without bacteria addition). Meanwhile, thermophilic period 3 treated groups was prolonged, NH3 N2O emissions significant reduced, especially for NF-3 treatment. Firmicutes preponderant stage, while Chloroflexi, Proteobacteria Bacteroidetes mature stage. These conformed addition composting improved bacterial community structure benefited retention.
