Metabolic network and genetic basis of aroma production in Saccharomyces hybrids

By incorporating phenotypic traits of their two original species, yeast hybrids exhibit a unique combination of properties and an array of fermentation products. For example, wine yeast hybrids can combine the low temperature tolerance of one parent with the profile of volatile molecules (aromas) produced by the other. This project will first aim to generate new Saccharomyces interspecies hybrids with metabolic phenotypes of interest for the wine industry. The second key point will be the identification of the metabolic network and genetic loci responsible for fermentative characters and formation of aroma and flavour by these strains.
