PHYSICO-CHEMICAL TREATMENT OF TANNERY EFFLUENT BY USING HALOPHILIC?BACTERIAL STRAIN?BACILLUS SUBTILIS?AND PROTEASE ENZYME

摘要

Production of untreated effluents which cause the pollution of air, water, soil and soil solid waste were the results of noval industries or enlargement of existing industries.In recent years, industrial effluents have been regarded as common source of pollution due to inappropriate disposal methods by industries.Water pollution is the major pollution that effects the environment much and one of the sources of this pollution is tannery industrial effluents.Effluents are so toxic that fishes cannot survivein it even for two hours and also effects the drinking water and hence it should be treated effectively before release.Bioremediation is the only way to tackle these xenobiotics and reduce the pollutants which is eco-friendly.The present work is an attempt which has been made to analyze the effectiveness of Bacillus subtilis against tannery effluents.The substrate can be degraded by specific protein breakdown enzymes secreted by some microbes.In several industries like pharmaceuticals, textiles and leather, proteases can be app lied.The production and activity of other available enzymes have to be studied for applying in various cost effective process.
