Studies on the Bacteria Isolated from Wine

Part IV Distribution of the Growth Factor for a Bacterium Inducing Malo-lactic Fermentation

Abstract

A malo-lactic fermentation (MLF) bacterium isolated from wine requires a factor contained in tomato juice for its growth. This type of the growth stimulating substance is found in several plants, particularly those belonging to fruits. The content of the factor in grapes varies depending on the varieties, degree of ripeness and harvest time. From these observation the relationship between the induction of MLF and the activity of the factor of grapes was discussed.
