Abstract: The bacterial diversity and their population changes were investigated in acetate-fed aerobic granules cultivated in two Sequencing Batch Reactors (SBRs), A and B. The top nine dominant bacteria were isolated, and their growths were tracked in another two SBRs (C and D) which were cultivating granules without selection pressures. The nine bacterial population in C and D were compared to the references obtained from A and B. The failure to cultivate granules in C and D was attributed to the nine isolates being outcompeted by poor settling fast growing bacteria and failing to reach a critical population size.
