Tannery effluent contains enumerous quantities of chemicals and high level of pH, TDS, TSS, BOD and COD which gets directly into natural aquatic environment, thus contaminate to the water quality. Hence it is important to develop an eco-friendly and cost-effective technology to treat the tannery effluent. Our present research work has been carried out to analyze the physico-chemical characteristics of tannery effluent and to reduce the load of pH, BOD and COD by the process of bioremediation using microorganisms. Among the physical chemical parameters analyzed pH, BOD and COD were found to be very high. Bacillus cereus and Pseudomonas aeruginosa, were identified and isolated and used in the reduction of pH, BOD and COD in the tannery effluent. Four different concentrations of untreated tannery effluents (control, 25, 50, 75 and 100%) were prepared. The experiment was carried out for 48 hrs (2 days). It is inferred from the results that Bacillus cereus to be more effective in reducing pH, BOD and COD than the bacterium, Pseudomonas aeruginosa in the untreated tannery effluents
