| Abstract:
A phenotypical characterization of ethanol tolerance of 265 Saccharomyces cerevisiae strains was carried out with the purpose to study their ecological diversity during alcoholic fermentation of wines elaborated in "O Baixo Miño" area and thus, select the ethanol resistant strains. This area comprises two subzones. Significant differences for the ethanol tolerance of strains responsible for fermentation in both subzones were found. In one of the subzones, significant differences were also found in the ethanol tolerance of the strains involved in the winemaking process, while in the other subzone, a randomly distribution of such strains was observed. | |
