Bioremediation of Textile Disperse Dyes using White-Rot Fungi Trametes versicolor

Abstract

Disperse dyes, frequently used in textile dyeing processes, present a particular challenge because of their recalcitrant nature. With an emphasis on wastewater effluent treatment, white-rot fungi Trametes versicolor were used. The fungus was cultured on different media and optimized various biochemical parameters (temperature, pH, inoculum size, dye concentration, and culturing time). After their biomass, disperse Red-I (DR1) and disperse Blue-I (DB1), and textile wastewater were biodegraded with the fungi T. versicolor. The growth of T. versicolor is time taking but maximum degradation by T. versicolor (0.02 to -0.11 during 3 days) is observed. In DB1 solutions and wastewater, absorbance values started at different points. However, the efficiency of fungi was found to be more than 80%. The potential of degradation of fungi in wastewater treatment can be further maximized to reduce environmental impact
