(a) Growth curves of L. monocytogenes individual strains on PALCAM agar at 5°C (i), 10°C (ii), 15°C (iii), and 20°C (iv). Growth curves of L. monocytogenes cocktail strains (b) and LAB (c) on MRS agar over time at the four different temperatures studied, (5, 10, 15, and 20°C). Arrows indicate the end of storage at each temperature.
