摘要

fermenting microorganism producing high concentrations of glycerol and their applications in the production of alcoholic / wine beverages.; The present invention describes two yeast strains, BM58 (CECT13003) and BM60 (CECT13004), belonging to the species Saccharomyces bayanus (var. Uvarum) and S. cerevisiae respectively, not genetically engineered, selected natural wine fermentations with good fermentative capacity musts for obtaining alcoholic beverages, preferably wine. The wines obtained with said yeast are characterized by high concentrations of glycerol without increasing the acetic acid and an increase in the production of certain secondary aromas. Both yeast mainly produce aromas ethyl esters such as ethyl caproate, ethyl caprylate, diethyl succinate and ethyl caprate. Finally, note the high capacity implementation in wine fermentations and the ability to grow at low temperatures (10 ° C) of these yeasts.
