Abstract
In warm regions potential alcoholic degree and unequilibrated must, especially in acidity are real problems to be resolved. Strains of Saccharomyces cerevisiae have different yields to produce ethanol from the same content of sugars. These peculiarities can be named glycolytic inefficiencies. We can select yeast strains with these properties in order to reduce the final alcoholic degree together with the production of some metabolic intermediates that can have repercussion in the sensorial profile like polyalcohols or organic acids (Figure 1). The aim of this work was select Saccharomyces cerevisiae with low ethanol production and the detection and use of some metabolic inhibitors which are able to deviate the conventional glycolysis to the production of other molecules than ethanol.
