Antibacterial activity of citrus fruit juices against Vibrio species.
Lemon, lime and sudachi juices were tested for antibacterial activity against seven strains of Vibrio species. All juices were effective in inhibiting the growth of the Vibrio strains. Citric acid, the major organic acid in these juices, was found to be responsible for inhibiting the growth of Vibrio parahaemolyticus. Sauce prepared from sudachi juice showed a strong bactericidal activity against Vibrio parahaemolyticus, whereas the sauce adjusted to higher pH values had no bacterial activity. Diluted sudachi juice or citric acid solution also had antibacterial activity independently. These results suggest that citrus fruit juices are effective in preventing infection with Vibrio species.
