ASSESSMENT OF AN EFFECTIVE BIOTIC AGENT FOR MANAGEMENT OF DISTILLERY WASTE THROUGH ASPERGILLUSNIGER AND ITS MUTANTSSHUBHANGINI SHARMA1 AND PALLAVI MITTALAbstract The disposal of distillery effluents is one of the main environmental problems. As per the Central Pollution Control Board, Ministry of Environment & Forests (MoEF), Government of India, alcohol distilleries are listed at the top of Red Category industries having a high polluting potential. In this concern, Bioremediation plays a vital role. Therefore, the present investigation deals with the bioremediation of distillery waste with Aspergillus niger (wild designated as control)and its mutants has been strategic to improve the eminence of treated effluent, so that it may triumph permissible standards for safe disposal. From this study, it was observed that for spent wash, reduction in COD is best attained by mutant 2 in comparison to control and mutant 1 and it is also reflected in the pH that is why lowest pH is also recorded in case of Aspergillus niger (mutant 2), However, color removal is not significant in case of mutant 2, it is superior in case of mutant 1. After treatment, reduction in COD and color is better attained in case of mutant 1. Although in all cases, best efficiency is obtained on sixth day, after that it has declined and overall mutant 1 (COD reduction up to 79 %) is better in comparisons to control and mutant 2. Hence this approach could be used to develop cost effective, eco-friendly biotechnology package for bioremediation of distillery waste before its disposal.
