     this study determined the most effective microbes acting as ammonia-oxidising (aob) and manganese-oxidising bacteria (mnob) for the simultaneous removal of ammonia (nh4+-n) and manganese (mn2+) from water. two conditions of mixed culture of bacteria: an acclimatised mixed culture (mixed culture: mc) in a 5-l bioreactor and biofilm attached on a plastic medium (stages of mixed culture: smc) in a biological aerated filter were isolated and identified using biolog microsystem and 16s rrna sequencing. a screening test for determining the most effective microbe in the removal of nh4+-n and mn2+ was initially performed using smc and mc, respectively, and found that bacillus cereus was the most effective microbe for the removal of nh4+-n and mn2+. moreover, the simultaneous nh4+-n and mn2+ removal (above 95% removal for both nh4+-n and mn2+) was achieved using a biological aerated filter under various operating conditions. thus, the strain could act as an effective microbe of aob and a mnob for the simultaneous removal of nh4+-n and mn2+.
