Characterization of cow dung microorganisms was carried out for determining its potential to degrade potent and widely accumulated petrochemical hydrocarbon Benzene. Physico-chemical and microbial parameters were studied and ten cultivable bacteria were isolated and identified. Out of these, five of the isolates survived at increasing concentrations of Benzene up to 100mg/L. Later, these five isolates were taken as a consortium and bioremediation of benzene at varying concentrations at 50, 100, 200 and 400mg/L was carried out. Benzene was found to be completely degraded at 50mg/L and 100g/L concentration within 96 hr and 144hr whereas, 99 percent degradation was observed for 200 mg/L and up to 69.2 percent for 400mg/L of benzene. These findings help to have an insight about indigenous source of biomass (like cow dung) and its effectiveness to develop an environmental friendly treatment technology for remediation of hydrocarbons like benzene.
