description

This study investigated the influence of nitrogen content on both β-glucosidase and β-xylosidase activities from non-Saccharomyces yeasts. Enzymatic activities were induced by the presence of xylan polysaccharides in the medium. Results show that optimizing β-glucosidase and β-xylosidase enzymatic activities can be determined not only by sugar or ethanol content or pH, but also by the concentration of N in the medium. This is the first work studying the influence of N content on glycolytic enzymes produced by non-Saccharomyces yeasts.
