In a previous study, we found that baker's yeast, added to remove the sugar in a colored syrup preparation for candy adsorbed the coal-tar dyes. In this paper, the effect of environmental conditions on dye adsorption of yeast cells in Reported. The concentration of glucose, reaction time and pH, as well as incubation temperature, affected dye adsorption. The various sugars used in addition to glucose, fructose and mannose were similar to glucose in their effect. However, no effect was observed with galactose, pentoses, or pyruvic acid. The dye adsorption was inhibited by the use of either 0.02 M Na-fluoride or 0.001 M iodoacetate in a reaction mixture containing glucose. No effect of nitrogen sources on dye adsorption was observed. In the presence of glucose, living cells of Saccharomyces cerevisiae; and starved cells adsorbed dye at the same rate. Although dead cells adsorbed dye markedly, no effect was observed when glucose was added. It may be concluded that the mechanism of coal-tar dye adsorption by living cells of yeast differs from that of dead cells and is related to glycolysis in yeast.
