Growth stimulants in plant extracts for Leuconostoc citrovorum.
The growth of Leuconostoc citrovorum ML 34, an isolate associated with the malo-lactic fermentation of wine, was stimulated in part by grape, orange, cabbage, and tomato juices. The stimulatory activity of tomato serum was associated with the carbohydrate fraction. Further purification of the fraction showed that fructose was the factor responsible for initiating growth. In addition to fructose, the organism required CO(2) for establishing growth. Saturated CO(2) atmosphere and catalytic amounts of fructose served as substitutes for plant extracts in a complex glucose medium.
