Abstract
The main cause of aquatic pollution is the water effluents from the textile industries. To bioremediate the dye some micro-organisms can be used especially, the fungus present in the soil can bioremediate the dye. The fungal strains were isolated from the dye-affected soil. The soil sample was collected from the Noyal river near A. Valasu, taluk Kangayam, district Tirupur, Tamil Nadu, India. The isolated fungus was studied morphologically and confirmed as Aspergillus flavus then the fungus was subjected to physical and chemical mutagens, such as UV light and ethyl methyl sulphonate. Finally, the degradation capacity of the wild and mutant Aspergillus flavus was screened against congo red using calorimetry. it was observed that 70.58% of degradation was done by wild fungi whereas 78.43% of degradation was observed on mutant type with Congo red. Thus, it was proved that the mutant fungal strain could degrade the Congo red faster than wild-type strain.
