Hydrolysis and transport of maltose into Schwanniomyces castellii was studied under aerobic and anaerobic conditions. Amylase and glucosidase were not synthetized in presence of maltose in anaerobic conditions. Maltose permease was synthetized in anaerobiosis and its functioning is not inhibited. Glucose strongly repressed induction. The half‐saturation constant for uptake of maltose was 0.06 mM. The rate of uptake of maltose was decreased by 2,4‐dinitrophenol, antimycin or sodium azide. The significance of these results in relation to the K LUYVER effect is discussed.
