Growth inhibition of enteric bacteria by Vibrio cholerae in nutrient media containing lactate, acetate, or citrate.


In cross-streak tests on nutrient agar containing lactate, acetate, or citrate, the growth of certain enteric bacteria was inhibited by themselves or by Vibrio cholerae, or by both. This mimicked the activity of bacteriocins, but the phenomenon was attributable to the accumulation of carbonate and increased alkalinity of the media.
