Biodegradation of malachite green dye by Saccharomyces cerevisiae and Candida albicans Isolated from Textile Effluent.

Abstract

Malachite green (MG) degradation by Saccharomyces cerevisiae, Candida albicans and their consortium isolated from textile effluent, were investigated under aerobic condition using 20 mg of the dye in 250 ml, 500 ml and 750 ml of mineral salt medium for a periods of 12 days. Biodegradation activities were monitored using UV Spectrophotometer at 617 nm wavelength. The results shows 48%, 68% and 70% degradation by Saccharomyces cerevisiae for 250 ml, 500 ml and 750 ml dilutions respectively at the end of 12 days, while 48%, 65% and 68% degradation by Candida albicans were observed for 250 ml, 500 ml and 750 ml dilutions respectively at the end of 12 days. 52%, 70% and 77% degradation by their consortium for 250 ml, 500 ml and 750 ml dilutions respectively at the end of 12 days were also observed. The results of this study revealed the ability of Saccharomyces cerevisiae, Candida albicans and their consortium for the treatment of effluent containing malachite green dye.
