Fig. 4From: Hyperthermophilic pretreatment composting can reduce ammonia emissions by controlling proteolytic bacterial community and the physicochemical propertiesRedundancy analysis (RDA) between proteolytic bacterial npr (a) and sub (b) taxa (relative abundances of the dominant species at top 5) and environmental parameters (TOC, TN, EC, DOC, TEP, NH4+ and Protase) in the TC (traditional composting) and HPC (hyperthermophilic pretreatment composting) by Day 0, 20, 40 and 60. TOC: total organic carbon, TN: total nitrogen, EC: electricity conductivity, DOC: dissolved organic carbon, TEP: temperature. The prefix “Unclassified” represented unclassified speciesBack to article page
