Under anaerobic conditions, two fermentable hexoses were added simultaneously to a yeast suspension. A new kinetic model for the sugar transport through the yeast cell membrane was suggested, and an equation about the sugar consumption rate in the mixture was introduced. This equation is based on the assumptions that these sugars are transported by a carrier facilitating diffusion mechanism, combining these sgars with carrier molecules, corresponding to each sugar and that these sibstrate-carrier complexes are affinitive each other, and the substrate and carrier inside the heteroconplex, so called the allosteric effect.During the fermentation of a binaty sugar mixture in yeast, sugar concentration in the medium were determined from time to time. The following results supporting the above assumptions were obtained;1. The linear relations existed between the logarithmas of the cooncentration of the two sugars at any time.2. In a glucose-fructose mixture, the experimental results areed for the most part with the theoretical curves, obtained from above equartions.
