Identification of genes required for decolorization of crystal violet in Citrobacter sp.MY-5

摘要

Triphenylmethane dyes are aromatic xenobiotic compounds,and are used extensively in textile industries for dying nylon,wool,silk and cotton(Gregory,1993).Significantly,some dyes have been shown to be mutagens,mitotic poisons or clastogens(Au et al.,1978,1979).The degradation of dyes has received considerable attention from the viewpoint of treating industrial wastewater containing dyes.Studies on the biodegradation of triphenylmethane dyes have focused primarily on the decolorization of dyes via reduction reactions(Azmi et al.,1998).
