Genetic identification of the yeast Saccharomyces kudriavzevii from European population

Using genetic hybridization analysis we showed for the first time that Portuguese isolates belong to the biological species Saccharomyces kudriavzevii Naumov et al. (2000). Earlierthis species was described on Japanese isolates. Divergence of Portuguese and Japanese S. kudriavzevii populations, as well as different S. cerevisiae populations, on molecular galactose markers is discussed.
