The effect of ethanol and sugars on rates of fermentation was studied. A strain of Candida pseudotropicalis was used. The specific rate of fermentation was determined by using the Warburg manometer. The effect of ethanol was formulated as an exponential function of ethanol concentration, but the empirical constant was different when glucose or lactose was used as a substrate. The effects of both ethanol and substrate were formulated. It was demonstrated that when lactose and glucose were present in the medium with a small amount of alcohol, a synergistic effect on the rate of fermentation appeared. This phenomenon considerably limits the rate of fermentation.
