DEGRADATION OF AZODYES PRESENT IN TEXTILE EFFLUENTS
Asmeet Kaur, Preethi Jeyakumar, Anchana Devi C., Anita Singh and Priya Iyer*
ABSTRACT The textile effluents were collected and characterized for its physicochemical properties. The effluents were cultured in half strength Nutrient Broth and the isolated organisms were identified by biochemical characterization. Optimum growth conditions were standardised. Dye discoloration activity was determined by taking the optical density after every 24 hours. Discolorization was studied by combinations of organisms. Plasmid was isolated from the organisms and competent cells were prepared for carrying out transformation for effective dye degradation. Percentage discolorization was found. A thin layer chromatography was carried out to confirm the degradation assay. The toxicity of the products formed after degradation was tested. Keywords: Azo dyes, textile effluents, microorganisms.
