Inhibition of Salmonella typhimurium by the products of tartrate metabolism by a Veillonella species

The inhibition of the growth of Salmonella typhimurium by a Veillonella species grown on media supplemented with tartrate was examined. Growth of Salmonella typhimurium was not inhibited by the concentrations of products metabolized by Veillonella cultures on media supplemented with 0 or 50 mmol l-1 of tartrate, but was inhibited on media supplemented with 100 or 150 mmol l-1 of tartrate. Inhibition of Salm. typhimurium was correlated with the increased production of acetate and propionate from tartrate by the Veillonella species.
