Wine yeast phenomics: A standardized fermentation method for assessing quantitative traits of Saccharomyces cerevisiae strains in enological conditions
This work describes the set up of a small scale fermentation methodology for measuring quantitative traits of hundreds of samples in an enological context. By using standardized screw cap vessels, the alcoholic fermentation kinetics of Saccharomyces cerevisiae strains were measured by following their weight loss over the time. This dispositive was coupled with robotized enzymatic assays for mea...
متن کاملDifferentiation of industrial wine yeast strains using microsatellite markers.
AIMS To differentiate nine industrial wine strains of Saccharomyces cerevisiae using microsatellite (simple sequence repeats, SSR) markers. METHODS AND RESULTS Six of the strains were indigenous yeasts currently used as high-density starter monocultures by the Uruguayan wine industry. Unequivocal differentiation of these six native strains and three commercial S. cerevisiae wine strains was a...
متن کاملComparative transcriptomic and proteomic profiling of industrial wine yeast strains.
The geno- and phenotypic diversity of commercial Saccharomyces cerevisiae wine yeast strains provides an opportunity to apply the system-wide approaches that are reasonably well established for laboratory strains to generate insight into the functioning of complex cellular networks in industrial environments. We have previously analyzed the transcriptomes of five industrial wine yeast strains a...

متن کاملMeiotic chromosome segregation in triploid strains of Saccharomyces cerevisiae.
Meiosis in triploids results in four highly aneuploid gametes because six copies of each homolog must be segregated into four meiotic products. Using DNA microarrays and other physical approaches, we examined meiotic chromosome segregation in triploid strains of Saccharomyces cerevisiae. In most tetrads with four viable spores, two of the spores had two copies of a given homolog and two spores ...
