Jv. Gimeno-alcaniz et al., Differential pattern of trehalose accumulation in wine yeast strains during the microvinification process, BIOTECH LET, 21(4), 1999, pp. 271-274
Trehalose accumulation in wine yeast strains growing under microvinificatio
n conditions was determined and compared to that obtained under laboratory
conditions. Industrial strains accumulate 10-fold more trehalose than labor
atory strains. Contrary to batch-culture growth, under microvinification co
nditions trehalose accumulation is not consequence of glucose exhaustion. P
hysiological relevance of trehalose during the process of wine making and t
heir use for potential improvements of alcoholic fermentation are discussed
.
