Abstract

A simple and practical biological process for the decolorization and degradation of dyes is described. In this study, an aerobic Gram positive bacterium was used for the decolorization and degradation of different types of dyes, like triphenyl methane, fluorine and acid dyes. The dyes used in this study were Eosin Y (fluorine), Methyl Green (triphenyl methane), Brilliant Blue R (acid dye), Crystal violet (triphenyl methane), and Basic Fuchsin (triphenyl methane). The bacterium was able to use these dyes as a sole source of carbon for its growth. Absorption spectral studies provided the evidence for decolorization. The color loss is not reversible upon exposure to air, indicating that the dyes are indeed degraded by the bacterium. Since the bacterium is capable of decolorizing different types of dyes, it could be commercially exploited for its application in treatment of textile effluents.
