Investigation of the dominance behavior of Saccharomyces cerevisiae strains during wine fermentation
Benedetta Perrone, Simone Giacosa, Luca Rolle, Luca Cocolin, Kalliopi Rantsiou; International Journal of Food Microbiology, Volume 165, Issue 2, 15 Ju
During wine fermentation, different strains of Saccharomyces cerevisiae compete in the same fermenting must and dominance takes place when one strain overcomes all the others. The purpose of this s...
