Summary:In this work industrial wine yeast strains of Saccharomyces cerevisiae and Saccharomyces bayanus were characterized for their phenotypic and genetic traits. Significant differences were found for biochemical and physiological features. The hybrids' good ability of L-malate biodegradation in fermentation process, that reached up to 76.9 percent, was observed. Wine yeast strains and their hybrids had unique chromosomal and mitochondrial DNA patterns and showed evident length polymorphism. However, the differences among strains did not appear clear enough to define species designations and relationships among hybrids and parental strains. Aneuploid state of hybrids and their different, in comparison with parental strains, chromosomal DNA profiles might be caused by unequal segregation of chromosomes before sporulation process
