Characterization of malolactic bacteria isolated from Aosta Valley wines and evidence of psychrotrophy in some strains

摘要

AimA survey on indigenous malolactic bacteria populations isolated from wines produced in 13 different wineries of Aosta Valley, the highest vine-growing area in Europe, was carried out in order to characterize the dominant strains in spontaneous malolactic fermentation (MLF) and to reveal the appearance of psychrotrophic ones.
