Abstract

In the present study, an attempt was made to examine the potential of aerobic fungal culture for decolourization of Brown GR textile dye. The effect of carbon source, nitrogen source, pH, temperature, NaCl concentration of dye was studied with an aim to determine the optimal conditions required for maximum decolourization and degradation. The fungal culture exhibited maximum decolourization ability at pH between 6-7 and at 25°C.1% (v/v) inoculums 10 spores/ml with fructose sugar were found to be the optimum for decolourization. A maximum of 82% decolourization was observed at 0.05% initial concentration of dye after 5 days of incubation period. The results show that the fungal culture from environment has good potential in removal of Brown GR dye under aerobic conditions.
