Description

Antibacterial action of Na-citrate in combination with Na-cholate was investigated on some Gram-negative bacteria involved in food poisoning and food spoilage.<br>Vibrio groups (V. cholerae non-01, V. fluvialis and V. parahaemolyticus) and Plesiomonas shigelloides were inhibited by 0.1 or 0.2M Na-citrate and 0.1% Na-cholate at pH 7.0, but higher amounts of both acids were required for inhibition at pH 8.0. Campylobacter jejuni and Yersinia enterocolitica were inhibited by 0.04M Na-citrate and 0.1% Na-cholate, and by 0.2M Na-citrate and 0.2% Na-cholate, respectively. Inhibition by combined Na-citrate and Na-cholate was also observed on the growth of Aeromonas hydrophila, Alcaligenes faecalis, Citrobacter freundii, Escherichia coil, Proteus vulgaris, Pseudomonas fluorescens and Serratia marcescens.<br>Based on the above results, the effectiveness of combinations of citric acid (as a food component) and bile acids for inhibiting the growth of food poisoning bacteria in the human intestine is discussed.
