    Abstract:
    Cell cultures of Blumea malcolmii Hook., developed in the laboratory, rapidly decolorized textile industry effluent along with a variety of dyes with diverse structural properties. Most rapid decolorization was observed in case of Malachite Green (93.41% decolorization within 24 h). The cells were capable of tolerating and degrading high concentrations of the dye, thus making them remarkable systems for phytoremediation studies. The enzymatic analysis during decolorization of Malachite Green showed the induction of enzymes such as laccase, veratryl alcohol oxidase and DCIP reductase indicating the involvement of these enzymes in the degradation of the dye. The cell cultures also mediated the remediation of textile industry effluent by bringing about a decrease in the BOD, COD and ADMI values of the effluent within 48 h. Phytotransformation was confirmed with the help of HPLC and the probable fate of metabolism of the dye was predicted with the help of GCMS analysis.
