Genomic adaptation of an autochthonous cider yeast strain to buckwheat and barley wort under stressful brewing conditions.

ABSTRACT: Growing consumer demand for specialty beers with unique flavors and enhanced nutritional properties is driving the development of novel, high-performance industrial yeasts. However, the genetic diversity of beer yeast strains is limited. Traditional spontaneous fermentations are a rich source of new strains that are well adapted to fermentative environments but lack the ability to efficiently convert maltose-based substrates that are rich in polyphenols (e.g., buckwheat wort) or maltotriose-rich substrates (e.g., barley wort). To simulate the selection pressure exerted on beer yeasts during domestication, we used adaptive laboratory evolution to yield cider yeast Saccharomyces cerevisiae that can efficiently convert buckwheat and barley wort into beer. To this end, 30 serial transfe
