L. monocytogenes survival in acidified BHI. L. monocytogenes 10403S was grown to log phase (A) or stationary phase (B) at 37°C (gray bars) and 7°C (white bars) before the cultures were adjusted to pH 3.5 and incubated at 37°C for various amounts of time. Log reduction is log10 CFU/ml before treatment minus log10 CFU/ml after treatment. Time points showing statistically lower log reduction (i.e., higher survival) in 37°C-grown cells are marked with an asterisk. Bars show the averages of three biological replicates; error bars represent standard deviations.
