Isolation and characterization of haploid heterothallic beer yeasts.

Abstract excerpt

Improving ale or lager yeasts by conventional breeding is a non-trivial task. Domestication of lager yeasts, which are hybrids between Saccharomyces cerevisiae and Saccharomyces eubayanus, has led to evolved strains with severely reduced or abolished sexual reproduction capabilities, due to, e.g. postzygotic barriers. On the other hand, S. cerevisiae ale yeasts, particularly Kveik ale yeast strains, were shown to...
