Biodecolorization of methylene blue using aspergillus consortium

Abstract

Abstract To establish sustainable circular ecosystems, the immense knowledge of different fungal strains as pure and mixed isolates and application them in biodecolorization of dye-laden wastewater is required. In this study, the biodecolorization of methylene blue (MB) dye was investigated by using mixed microfungal strains of Aspergillus consortium consisting of Aspergillus niger, Aspergillus flavus and Aspergillus fumigatus . The experiments were conducted in batch-mode. Analytical measurements were performed by UV-VIS spectroscopy. Optimization of operating conditions was carried out in order to achieve the optimal biodecolorization of methylene blue dye (MB). Furthermore, the results illustrated that 36 hrs., 30°C, 9, 2g/L and 150mg/L for incubation time, temperature, initial pH, fungal inoculum size and MB dye concentration, respectively, were chosen as the optimum conditions with the maximum biodecolorization of MB dye was 92%.
