A defined medium with glucose as the carbon source was used to
quantitatively determine the metabolic end products produced by Listeria
monocytogenes under aerobic and anaerobic conditions. Of 10 strains tested,
all produced acetoin under aerobic conditions but not anaerobic conditions.
Percent carbon recoveries of end products, typified by strain F5069, were
as follows: lactate, 28%; acetate, 23%; and acetoin, 26% for aerobic growth
and lactate, 79%; acetate, 2%; formate, 5.4%; ethanol, 7.8%; and carbon
dioxide, 2.3% for anaerobic growth. No attempt to determine carbon dioxide
under aerobic growth conditions was made. The possibility of using acetoin
production to assay for growth of L. monocytogenes under defined conditions
should be considered.
