FIG. 2.

Maximum specific growth rates of Listeria monocytogenes LO28 WT and 24 HHP-resistant variants at 30°C in BHI under aerobic conditions (a); at 30°C in BHI under anaerobic conditions (b); or at 7°C in BHI under aerobic conditions (c). (d) Colony size (in mm) was determined by measuring the diameters of colonies after 2 days of growth at 30°C on BHI agar under aerobic conditions. Each growth experiment was reproduced at least two times on different days. The error bars show 1 standard deviation. Results in gray bars are not statistically different, whereas white bars show significant differences compared to the wild type.
