Table 2.

Growth parameters lag time (λ), maximum specific growth rate (μmax) and stationary phase cell density for triplicate cocultures studies of Listeria monocytogenes and Listeria innocua grown at 30°C and inoculated at two inoculum ratios (Low:Low and High:High) in two different growth media (UVM and TSB).

Growth medium Inoculum ratio (L. monocytogenes: L. innocua)a Listeria species λ (h)b μmax (h1)b Stationary phase cell density (log10 CFU/ml)b
UVM High:High monocytogenes 1.95 ± 0.17A 5.65 ± 0.04A 6.47 ± 0.02A
Innocua 2.56 ± 0.43A 5.82 ± 0.06A 6.41 ± 0.02A
UVM Low:Low monocytogenes 12.74 ± 0.45B 5.68 ± 0.11A 6.38 ± 0.05AB
innocua 13.20 ± 0.45B 5.79 ± 0.07A 6.64 ± 0.07B
TSB Low:Low monocytogenes 9.27 ± 0.45C 6.64 ± 0.11B 7.17 ± 0.06C
innocua 9.24 ± 0.76C 6.44 ± 0.12B 6.89 ± 0.09B
