Listeria monocytogenes together with Gram‐positive and Gram‐negative bacteria was grown in axenic cultures in meat juice under an atmosphere enriched with carbon dioxide at 4°C. The size of the final population of listeriae was determined by that of the initial inoculum. Growth of L. monocytogenes ceased with glucose depletion. Glucose‐6‐phosphate was not catabolized by listeriae. In aerobic axenic cultures generation times of L. monocytogenes were shorter and glucose depletion was faster than with a carbon dioxide‐enriched atmosphere. Oxidation of L‐ and D‐lactic to acetic acid was probably associated with the subsequent die‐off of L. monocytogenes.
