KEGG categories differed significantly between DGW samples and their correlation with physicochemical properties. a The level 3 KEGG ortholog function predictions of the relative abundance of the top 50 metabolic pathways. b Pearson correlation analysis between metabolic pathway in a and physicochemical properties of compost. M1, M2, and M3 represent the samples from mesophilic, thermophilic, and cooling phases of Compost M, respectively, while C1, C2, and C3 represent the samples from mesophilic, thermophilic, and cooling phases of Compost C. *p < 0.05, **p < 0.01
