This study aims to model the effects of acid and osmotic shifts on theintermediate lag time of Listeria monocytogenes at 10°C in a growth medium. The model was developed from data from a previous study (C. I. A. Belessi, Y. Le Marc, S. I. Merkouri, A. S. Gounadaki, S. Schvartzman, K. Jordan, E. H. Drosinos, and P. N. Skandamis, submitted for publication) on the effects of osmotic and pH shifts on the kinetics of L. monocytogenes. The predictive ability of the model was assessed on new data in milk. The effects of shifts were modeled through the dependence of the parameter h0 (""work to be done""prior to growth) induced on the magnitude of the shift and/or the stringency of the new environmental conditions. For shifts acrossthe boundary, the lag time was found to be affected by the length of time fo which the microorganisms were kept at growth-inhibiting conditions. The predicted concentrations of L. monocytogenes in milk were overestimated whenthe effects of this shift were not taken into account. Th model proved to be suitable to describe the effects of osmotic and acid shifts observed bothwithin the growth domain and across the growth boundaries of L. monocytogenes. © 2010 American Society for Microbiology. |
