Abstract: | "Of 31 yeasts, from different surfaces of two cellars from the northwest region of Argentina, 11 expressed killer activity against the sensitive strain Saccharomyces cerevisiae P351. Five of these killer yeasts were identified as S. cerevisiae by phenotypic tests and PCR-RFLP analysis. Two S. cerevisiae killer strains, Cf5 and Cf8, were selected based on their excellent kinetic and enological properties as potential autochthonous mixed starter cultures to be used during wine fermentation. They could dominate the natural microbiota in fermentation vats and keep the typical sensorial characteristics of the wine of this region" |
