Abstract

Five heavy metals tolerant bacteria were isolated from petroleum refinery effluent and identified as Pseudomonas aeruginosa, Staphylococcus aureus, E. coli, Proteus vulgaris and Klebsiella pneumoniae. Each isolate was inoculated into different concentrations of cadmium, chromium, nickel and zinc to determine its maximum tolerance for each heavy metal. All five isolates had low maximum tolerance concentration for cadmium (0.9 mg/L) when compared to chromium (5 mg/L), nickel (5 mg/L) and zinc (7 mg/L). Mixed culture consortium (MCC) remediated high percentage of cadmium (100%), chromium (33.4%), nickel (73.9%), and zinc (90.1%) from the petroleum refinery effluent than pure culture isolates. Among the pure culture isolates Pseudomonas aeruginosa (Cd (100%), Cr (23.1%), Ni (64.3%) & Zn (53.9%) yielded high values for the reduction of heavy metals in the refinery effluent when compared to Staphylococcus aureus, E.coli, Proteus vulgaris and Klebsiella pneumoniae. The isolated bacteria were effective for the remediation of heavy metals from petroleum refinery effluent.
