The first reported instance with this organism occurred in 1983 and resulted from a food poisoning outbreak due to the consumption of contaminated coleslaw. Since then, problems have occurred with numerous other foods. In this paper we report the products formed by L. monocytogenes when it grows in a speciall designed medium. The organism can grow either in the presence or absence of oxygen, but the compounds produced are different. This basic information will be helpful to other scientists and to us as we continue to design food preservation methods that will prevent the growth of this and other food pathogens. Technical Abstract: A defined medium with glucose as the carbon source was used to determine the metabolic end-products produced by Listeria monocytogenes under aerobic and anaerobic conditions. All strains performed a 2,3-butanediol fermentation under aerobic conditions, but produced ethanol and formate in lieu of acetoin anaerobically. Acetoin is an assayable constitutive metabolite that can be used to indicate L. monocytogenes metabolic activit in pure culture under defined conditions. |
