Batch experiments were carried out to investigate biodegradation of 4-Bromophenol (4-BP) and simultaneous removal of COD in anaerobic, anoxic and aerobic reactor with the help of heterogeneous microbial culture. The microbial consortium was acclimatized to degrade various concentrations of 4-BP such as 5, 10 and 15 mg/l within specific time period. Efficiency of batch bioreactor was determined by evaluating maximum removal of 4-BP and simultaneous removal of COD. Results revealed that 97, 90.54 and 98.99% removal of 4-BP and 76, 60 and 85% removal of COD was achieved in anaerobic, anoxic and aerobic reactor, respectively. Acclimated microbial culture responsible for 4-BP degradation was isolated and identified. Gram negative bacteria (Pseudomonas, Escherichia, Salmonella spp), rod shaped and round shaped bacteria were identified in microbial culture.
