BIODEGRADATION OF CAMEX GOLDEN YELLOW DYE USING BACTERIA

POONAM RANGA AND BALJEET SINGH SAHARAN

Abstract

Dyes are xenobiotic compounds that make the world more beautiful through coloured substances. However, the release of coloured effluent from textile industries represents a serious environmental problem and public health concern. Without adequate treatment, these dyes are stable and can remain in environment for an extended period of time. Various physico-chemical methods are being used for effluent treatment but they are highly expensive and results in large amount of sludge production. Keeping these points in mind the present investigation was planned for bioremediation of textile dye using bacteria. An aerobic bacterial isolate SPR42 (Bacillus subtilis) was able to decolourize Golden yellow 3RL (an azo dye) at a concentration of 100 mgL -1 upto 74% within 24 hrs at 37 OC and alkaline pH of 8.5 in static conditions. Thus, this microorganism seems to be potentially effective for biodegradation of textile dyes.
