Abstract: The aim of this study was to evaluate the bioconversion of metabolic inhibitors (furfural, o-vanillin, trans-cinnamic acid and copper) during alcoholic fermentation by Saccharomyces cerevisiae, and its effect on secondary metabolites production. The tested yeast shows a good activity to convert furfural and o-vanillin into their derivatives furfuryl alcohol and o-vanillyl alcohol, respectively, both detected in the respective mediums at final of fermentative process. Also, the production of higher alcohols was affected in the presence of o-vainillin and trans-cinnamic acid, and to a lesser extent of copper, with a marked effect obtained by discriminant analysis.
