Shifts in bacterial community composition and abundance of nitrifiers during aerobic granulation in two nitrifying sequencing batch reactors

[Display omitted] •Bacterial diversity decreased sharply in the post-granulation period.•Similar bacterial structure was observed in AGS formed with different wastewater.•Dominant genera in seed sludge were washed-out during aerobic granulation.•Bacteria with low relative abundance (
