Characterization of bromate-reducing bacterial isolates and their potential for drinking water treatment

Reduction of bromate in a biological activated carbon filter under high bulk dissolved oxygen conditions and characterization of bromate-reducing isolates

“…However, the removal of BrO 3 − in BAC filters decreased with the increase of DO and NO 3 − concentrations [9,10]. The two isolates acquired in the current study and some of the isolates acquired in the previous study [8] have exhibited BrO 3 − -removal capacity in the presence of NO 3 − (Fig. 4).…”

“…In addition, two BrO 3 − -reducing isolated in a previous study were close neighbors with Dechloromonas spp. [8]. In general, the clones belonging to the order Rhodocyclales in general exhibit the common ability to utilize chlorate, perchlorate, NO 3 − or BrO 3 − as the electron acceptors.…”

“…concentrations of DO and NO 3 − [8], whereas the removal of BrO 3 − decreased with the increase of DO and NO 3 − concentrations [9,10].…”

“…Furthermore, understanding the underlying mechanisms of BrO 3 − reduction would be very helpful for the removal of BrO 3 − using BAC filters. Recently, fifteen BrO 3 − -reducing bacteria from different phylogenetic groups were acquired from different sources [8]. Some denitrifying organisms were reported to be able to reduce BrO 3 − [5].…”

Degradation of Norgestrel by Bacteria from Activated Sludge: Comparison to Progesterone

“…47 According to previous studies, Aeromonas hydrophila is able to degrade azo dyes, 48,49 diesel oil, 50 and quaternary ammonium compounds, 51 and reduce bromate. 52 No previous study has reported that it could degrade steroids, not even norgestrel. Thus, this is the first report of the norgestrel-degradation ability of Aeromonas hydrophila.…”
