Transcriptional Profile of the Industrial Hybrid Saccharomyces pastorianus Reveals Temperature-Dependent Allele Expression Bias and Preferential Orthologous Protein Assemblies.

Saccharomyces pastorianus is a natural yeast evolved from different hybridization events between the mesophilic S. cerevisiae and the cold-tolerant S. eubayanus.

Improving the Cryotolerance of Wine Yeast by Interspecific Hybridization in the Genus .

Fermentations carried out at low temperatures (10-15°C) enhance the production and retention of flavor volatiles, but also increase the chances of slowing or arresting the process. Notwithstanding, as is the main species responsible for alcoholic fermentation, other species of the genus , such as cryophilic species , and , are better adapted to low-temperature fermentations during winemaking. In this work, a × hybrid was constructed to improve the enological features of a wine strain at low temperature.
