Moderate expression and activity of flocculins underlie the characteristic flocculation phenotype of Saccharomyces pastorianus
ABSTRACT Flocculation is a key technological trait in lager brewing, governing fermentation performance, yeast recovery, and beer quality. In the allo-aneuploid hybrid yeast Saccharomyces pastorianus, the genetic basis of flocculation remains poorly resolved due to its complex dual sub-genome architecture. Here, we sys...
