摘要
When 4% (v/v) ethanol was added progressively to two strains exhibiting different fermentative abilities, K1 (a commercial wine strain) and V5 (a strain derived of a wine yeast), the fermentation rate correlated directly to the ethanol concentration for both strains. In contrast, the effect of sudden addition of 2%, 4% or 6% (v/v) ethanol was different depending on the strain. While the same effect was observed for K1 whatever the way of ethanol addition, V5 required an adaptation period after the shock addition of ethanol.
