Shifts in bacterial community composition and abundance of nitrifiers during aerobic granulation, and the effects of wastewater composition on them were investigated using Illumina sequencing and quantitative PCR. The bacterial diversity decreased sharply during the post-granulation period. Although cultivated with different wastewater types, aerobic granular sludge (AGS) formed with similar bacterial structure. The bacterial structure in AGS was completely different from that of seed sludge. The minor genera in seed sludge, e.g., Arcobacter, Aeromonas, Flavobacterium and Acinetobacter, became the dominant genera in AGS. These genera have the potential to secrete excess extracellular polymer substances. Whereas, the dominant genera in seed sludge were found in less amount or even disappeared in AGS. During aerobic granulation, ammonia-oxidizing archaea were gradually washed-out. While, ammonia-oxidizing bacteria, complete ammonia oxidizers and nitrite-oxidizing bacteria were retained. Overall, in this study, the bacterial genera with low relative abundance in seed sludge are important for aerobic granulation.</description><identifier>ISSN: 0960-8524</identifier><identifier>EISSN: 1873-2976</identifier><identifier>DOI: 10.1016/j.biortech.2017.12.038</identifier><identifier>PMID: 29272774</identifier><language>eng</language><publisher>England: Elsevier Ltd</publisher><subject>Acinetobacter ; Aerobic granular sludge ; Aeromonas ; ammonia ; Archaea ; Arcobacter ; bacterial communities ; Bacterial community ; community structure ; Flavobacterium ; Illumina MiSeq sequencing ; Nitrification ; polymers ; quantitative polymerase chain reaction ; Sequencing batch reactor ; sludge ; technology ; wastewater</subject><ispartof>Bioresource technology, 2018-03, Vol.251, p.99-107</ispartof><rights>2017 Elsevier Ltd</rights><rights>Copyright © 2017 Elsevier Ltd.
