BIODEGRADATION OF TEXTILE DYES BY FREE AND IMMOBILIZED CELLS OF MICROORGANISMSB.V. PANDEY AND R. S. UPADHYAY
Four commercially used textile dyes namely, Procion Red Yellow, Acid Yellow-9 and Crystal Violet were better decolorized under aerobic liquid culture but Direct Orange-102 was comparatively more resistant to decolorization. Decolorization increased with the increase in incubation period. However, the efficiency decreased with increase in dyestuff concentration. Degradation was best achieved by immobilized cells as compared to free cells.
