This study reports the biodegradation capability of an indigenous fungal species Aspergillus foetidus for decolorization and removal of chemical oxygen demand from textile effluent. Model designed experiments were performed to construct the quadratic model and high regression coefficients between variables and responses indicated suitability of the model. Further, the experimental conditions were optimized for fungal species A. foetidus 8796 to show its efficiency to remove color from textile effluents. Aspergillus foetidus 8796 revealed up to 91.3% of color removal activity and 82.58% of chemical oxygen demand removal capability under the optimal conditions of this study. The extracellular enzymatic activities of this fungal species evidenced an excellent evaluation of experimental data to propose A. foetidus , as a cost effective solution to treat the effluents from textile industry.
