Abstract
Deoxyribonucleic acid reassociation studies of 24 different wine and beer-associated strains of Saccharomyces confirmed the presence of three separate species. S. cerevisiae and S. bayanus strains had only 22% of their genomes in common. S. pastorianus, with intermediate hybridization values between S. cerevisiae and S. bayanus (52 and 72%, respectively) could possibly be a natural hybrid of the two species. S. pastorianus replaces S. carlsbergensis with which it is homologous for 93% of its genome, since the former species was described first by Hansen in 1904. These data do not agree with the results of traditional physiological tests.Entities:
