Résumé: This work describes the use of a Bioscreen C automatic plate reader to monitor the effects of organic acids (acetic, lactic and sorbic acids) on the growth of Listeria innocua. Increasing the concentration of the organic acid increased the time to a detectable level by escalating cell metabolic effort for growth and reducing the subsequent growth rate. Sorbic acid is reported to be the more effective preservative. Stationary phase cells were less inhibited by lactic acid than cells in exponential growth.
