Research note: in vitro inhibition of Listeria monocytogenes growth by veillonellae cultures grown on tartrate media.
Veillonellae cultures were grown on agar media supplemented with tartrate and examined for inhibitory effects on the growth of Listeria monocytogenes. Veillonellae cultures grown on media supplemented with 0 or 50 mmol l-1 of tartrate did not inhibit the growth of L. monocytogenes; however, veillonellae grown on media supplemented with 100, 150 or 200 mmol l-1 of tartrate did inhibit the growth of L. monocytogenes. The inhibition of the growth of L. monocytogenes by the veillonellae was correlated with the increased production of acetate and propionate from tartrate by veillonellae and with the reduction of the pH of the media by L. monocytogenes.
