Chimeric genomes of natural hybrids of Saccharomyces cerevisiae and Saccharomyces kudriavzevii.
Recently, a new type of hybrid resulting from the hybridization between Saccharomyces cerevisiae and Saccharomyces kudriavzevii was described. These strains exhibit physiological properties of potential biotechnological interest. A preliminary characterization of these hybrids showed a trend to reduce the S. kudriavzevii fraction of the hybrid genome. We characterized the genomic constitution o...
متن کاملMolecular characterization of new natural hybrids of Saccharomyces cerevisiae and S. kudriavzevii in brewing.
We analyzed 24 beer strains from different origins by using PCR-restriction fragment length polymorphism analysis of different gene regions, and six new Saccharomyces cerevisiae x Saccharomyces kudriavzevii hybrid strains were found. This is the first time that the presence in brewing of this new type of hybrid has been demonstrated. From the comparative molecular analysis of these natural hybr...
متن کاملTranscriptomic analysis of Saccharomyces cerevisiae x Saccharomyces kudriavzevii hybrids during low temperature winemaking
BACKGROUND Although Saccharomyces cerevisiae is the most frequently isolated species in wine fermentation, and the most studied species, other species and interspecific hybrids have greatly attracted the interest of researchers in this field in the last few years, given their potential to solve new winemaking industry challenges. S. cerevisiae x S. kudriavzevii hybrids exhibit good fermentative...

متن کاملNatural hybrids of S. cerevisiae x S. kudriavzevii share alleles with European wild populations of Saccharomyces kudriavzevii.
Saccharomyces kudriavzevii, a yeast species described from a pair of strains isolated from decayed leaves in Japan, has recently been isolated from oak barks in Portugal. Some data suggest that these European S. kudriavzevii populations could be closely related to the S. kudriavzevii genetic background present in natural hybrids isolated from wines and beers in different regions of Europe. Howe...
