USE OF ASPERGILLUS NIGER FOR THE REDUCTION OF BIOLOGICAL OXYGEN DEMAND IN TEXTILE INDUSTRY EFFLUENT

Abstract

Textile industry utilizes large quantity of water and discharges highly contaminated waste water. The contaminants in effluents must be removed before entering into the water body, because it creates adverse effect on aquatic ecosystem. Bioremediation is one of the best methods for treating the industrial effluents. Bioremediation is the use of living organisms, to degrade the environmental contaminants into less toxic forms. It uses naturally occurring bacteria, fungi and plants to detoxify the pollutants in environment. In the present investigation, an attempt has been made to study the efficiency of Aspergillus niger in reducing the concentration of BOD from effluent. The result revealed that Aspergillus niger has great potential for reducing BOD concentration in textile industry effluent.
