Decolorization of different dyes by an indigenous strain of fungus was isolated from Eucalyptus tree .Thus based on 18S rRNA gene and ITS region homology, with the references strains, the isolates were identified as Mucor hiemalis MV04 (KR078215). 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 30C, 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.
