FIG 4.

(A and B) Growth of strains ΔpedE ΔpedH (blue dots), ΔglpFKRD (orange dots), ΔpedE ΔpedH ΔglpFKRD (gray dots), and ΔglpFKRD ΔgarK (green dots) in liquid M9 medium supplemented with 20 mM glycerol in the absence (A) or presence (B) of 10 μM La³⁺. (C) Growth of strains ΔpedE ΔpedH ΔglpFKRD (gray dots) and ΔgarK (yellow dots) in liquid M9 medium supplemented with 20 mM dl-glycerate in the absence of La³⁺. Incubation was performed in 96-well microtiter plates in a rotary shaker (Forma; Thermo Scientific) at 28°C and 220 rpm shaking. Data points represent averages of results from biological triplicates with the corresponding standard deviations.
