Studies On the Role of Fungal Strains in Bioremediation of Dyes Isolated from Textile Effluents

Abstract

Fungal strains are widely used for the cleaning of soil, sediments, groundwater, surface water, and the ecosystem. The presence of extracellular enzymes in fungi facilitates the process of bioremediation of textile dyes. This study was conducted to observe the quality of water being released from textile dyes industries and also the capability of some fungal strains which can remediate these dyes by showing the tendency of their resistance. Samples of water were collected from the polluted area surrounding the textile dyeing industries in Lahore. In the process of isolation, Potato Dextrose Agar (PDA) medium was used to verify the fungal growth. Fungal strains were purified, and the morphological characterization of fungal strains was carried out at 10X and 100X by using a magnification microscope. The fungal strains, such as Aspergillus niger, Aspergillusoryzae, and Aspergillusflavus were identified. The stress of four types of dyes was given to each fungal strain. The results showed that Aspergillusoryzae was one of the most stable, non-toxic, and resistant fungal species against the high stress of dyes as compared to other species.
