Biodegradation and Decolorization of Textile Azo Dyes by Paramecium caudatum Isolated from Industrial Wastewater

Azo dyes in textile industry effluent are one of the major toxic contaminants causing a severe threat to life. Bioremediation is most cost-effective and environmentally beneficial innovative biotechnologically technique used mitigate dyes’ effects aquatic environments. The purpose present study was determine azo degradation potential ciliate, Paramecium caudatum, isolated from industrial wastewater. Under optimum conditions, P. caudatum found possess 90.86% decolorizing ability RR2 (reactive red), 83.06% RB5 blue) 85.43% LY (Levafix reactive yellow) dyes. showed maximum growth at 25 °C pH 7.5 presence concentration 20 ppm (0.02 mg/mL). After being exposed RR2, RB5, dyes, level GSH increased for control i.e., 54, 43, 23%, respectively. Sequentially, GSSG decreased by 26% after treatment with dye, while exposure enhanced value more than twofold 0.86%. results decolorization biodegradation indicated that candidate effluents.
