In order to elucidate the mechanism of carbohydrate metabolism in hydrocarbon-assimilating yeasts, comparative studies were performed on the polysaccharide contents of cells of several kinds of yeasts, including four Candida species and two strains of newly isolated yeasts, cultivated in a hydrocarbon medium and in a glucose medium. In general, the content of total carbohydrates in the hydrocarbon-grown cells was found to be lower than that of the glucose-grown cells. In both types of cells the ratios of glucan to mannan, which were known as structural polysaccharides of the yeast cell wall, were approximately 1.0-2.0 when determined as monosaccharides. But these rations in Candida lipolytica and Candida tropicalis assumed fairly large values temporarily at the middle exponential growth phase. The glucan contents of both cells showed remarkable increases in the course of cultivation in both hydrocarbon and glucose media. No other qualitative differences between the hydrocarbon-grown and the glucose-grown cells were observed.
