Saccharomyces pastorianus

The yeast Saccharomyces carlsbergensis is used to brew bottom-fermented lagers and was named after the great Danish brewery Carlsberg, but is also in the scientific field, for example in the study of sub-processes of glycolysis with new procedures use.

History

The founder's son, Jacob Christian Jacobsen, who could include Louis Pasteur to his friends and colleagues, has a laboratory in 1875 in his father's brewery established, which later became the Carlsberg Research Center was established. In this laboratory, the first yeast cell was isolated in 1883. The discoverer was Emil Christian Hansen. Even today Hefereinzuchten in the so-called " Carlsberg flask " can be used in breweries.

Descent

S. carlsbergensis is a hybrid of Saccharomyces bayanus and Saccharomyces cerevisiae, so here are present phenotypic and genomic similarities to two types. The genome of S. carlsbergensis is up to 60% greater than that of S. cerevisiae, since parts of two genomes are included. However, it appears that the largest part of the genome of S. bayanus is derived. This part could also be from the 2011 discovered species S. eubayanus date that occurs naturally in contrast to S. bayanus.
