FIG 5.
Growth at various temperatures of wt and ΔcasKR strains from phylogenetic groups II, III, and V of B. cereus sensu lato. Growth of wt and ΔcasKR strains belonging to phylogenetic group II (strain MM3) (A, D, F), group III (strain AH187) (B, G), and group V (strain Rock 3-28) (C, E, H) was performed in an automated turbidimeter with shaking at 37°C (A to C), at a low temperature of 13°C (D) or 10°C (E), or at a temperature close to the Tmin of the strains of 8°C (F, H) or 12°C (G). y axes indicate the OD at 600 nm; x axes indicate time (in hours). Mean values ± SDs of three biological replicates are shown for each condition. Black curves, wt strains; gray curves, ΔcasKR mutants.
