Effect of furfural on the energy metabolism of fodder yeasts]

The effect of furfurol on the rate of oxygen uptake and carbon dioxide production by Candida tropicalis cells was studied. Furfurol was shown to inhibit significantly the yeast respiration, inducing aerobic glycolysis. Enhanced carbon dioxide production in the presence of furfurol was followed by an intensive degradation of trehalose and ethanol accumulation in the medium.
