Resumen de Concentration of amino acids in wine after the end of fermentation by Saccharomyces cerevisiae strains
Eva María Valero Blanco, Carmen Millán, José M. Ortega, Juan C Mauricio
Both quantitative and qualitative differences in the utilization and release of assimilable nitrogen by two wine strains of Saccharomyces cerevisiae (cerevisiae and capensis) under different conditions of oxygen were observed. These differences were influenced by the presence of oxygen at the beginning of the fermentation, and by the strain of S cerevisiae. The release of some amino acids post-fermentation may be the result of reoxidation of NAD(P)H in order to maintain a normal redox balance.
