From number of different synthetic dyes (RBBR, Malachite Green, and Congo red) Mucor hiemalis decolorize RBBR dye most efficiently. Maximum decolorization of 50 ppm RBBR dye was achieved temperature at 30°C, pH 5.0 and 130rpm shaking speed for both free and immobilized biomass. Complete decolorization was achieved in 8 days. It was also found from this study that immobilized biomass have higher decolorization capacity as compare to free fungal biomass. Copyright@ International Science Community Association
