FIG. 3.
Typical growth curves of encapsulated parent strain IU1781 (D39 rpsL1) and isogenic mutants IU2837 (D39 rpsL1 ΔspxB Δpta ΔackA), IU2687 (D39 rpsL1 Δpta), and IU2173 (D39 rpsL1 ΔspxB) in BHI broth at 37°C with limited aeration (static) in an atmosphere of 5% CO2 (see Materials and Methods). See Table S1 of the supplemental material for full genotypes. The experiment was repeated numerous times.
