Industrial pollution has been and continues to be a major factor causing the degradation of the environment around us, affecting the water we use, the air we breathe and the soil we live on. Among the various industries, sugar mill is one of the largest and most important agro based industries in India. The sugar industry is playing an important role in the economic development of the Indian sub continent, but the effluents released produce a high degree of organic pollution in both aquatic and terrestrial ecosystems. They also alter the physico-chemical characteristics of the receiving aquatic bodies and affect aquatic flora and fauna. Bioremediation of sugar-mill industrial effluents by microorganisms serves as an effective method to substitute the conventional recovery and removal process. In the present study, attempt has been made to isolate the native bacteria present in the sugar mill effluent collected from the Cheyyiar Co-operative Sugar Mills Ltd., Thiruvannamalai District and were tested for their individual bioremedial efficiency. The Staphylococcus aureus were capable of bringing about the bioremediation of Sugarmill effluent in the different concentration (Effluent different dilution+bacteria), (Effluent+different density of bacteria), (different pH of effluent+bacteria). It has been identified in terms of measuring their percentage of reduction potentials of parameters such as pH, EC, TDS, OD, BOD and COD. Maximum biodegrading potentials have been observed in the case of bacteria Staphylococcus aureus in all the different studies. i.e., pH(-52.77%), EC(24.47%), TDS(24.44%), BOD(70.32%) and COD(64.28%) amongst all. This result suggests that this can be recommended for treating various effluents.
