Rarefraction curve of observed npr (a) and sub (b) OTUs and the overall distribution of OTU-based npr (c) and sub (d) community dissimilarity during traditional composting (TC) and hyperthermophilic pretreatment composting (HPC) (based on unweighted UniFrac PCoA results). The number 0, 20, 40 and 60 represent different composting time. Different colors indicate composting days
