    Vacuolar H+-ATPase (V-ATPase) is thought to play a role in stress tolerance. In this study it was found that bottom-fermenting yeast strains, in which the V-ATPase-related genes DBF2, VMA41/CYS4/NHS5 and RAV2 were overexpressed, exhibited stronger ethanol tolerance than the parent strain and...
