Mycoremediation and toxicity assessment of textile effluent pertaining to its possible correlation with COD

Abstract Globally, textile industries are one of the major sectors releasing dye pollutants. This is the first report on the positive correlation between toxicity and chemical oxygen demand (COD) of textile effluent along with the proposed pathway for enzymatic degradation of acid orange 10 using Ge...
