Basic fuschin dye belongs to the most important group of synthetic colorants and is used extensively in the textile industries and clinical laboratories. Waste waters from these industries and laboratories washed down into flowing streams and rivers posed serious health hazard to the receiving communities. In this study, Saccharomyces cerevisiae isolated from a commercially prepared kunun-zaki was used to degrade 20mg basic fuschin dye for a period of 12 days under aerobic condition in 250, 500 and 750mL mineral salt media. The degree of decolourization of basic fuschin was determined using UV-visible spectrophotometer with absorbance of 620nm. At the end of twelve days 68%, 67% and 69% basic fuschin decolourization were recorded in 250mL, 500mL and 750mL concentration, respectively. The results suggest the potential of Saccharomyces cerevisiae for the treatment of waste water containing basic fuschin.
