原始语种摘要: Abstract(#br)A new denitrifying phosphorus-accumulating bacterium HW-15 was screened out from phosphorus-rich wastewater and was identified as Enterobacter cloacae sp. based on its physiological-biochemical characteristics and 16S rDNA sequence analysis. The shift in microbial community structure during acclimation was determined through high-throughput sequencing and Enterobacter was found to be the dominant genus. Strain HW-15 exhibited efficient simultaneous denitrifying and phosphorus removal, and achieved both heterotrophic nitrification and aerobic denitrification process, and demonstrated a preference for consuming nitrogen sources in order of NH+ 4-N>NO- 3-N>NO- 2-N. The application of strain HW-15 in real...
