FIG 3.

Growth kinetics of B. abortus 2308, the isogenic ΔpykM mutant JEP2, and a derivative of JEP2 in which the pykM locus has been reconstructed (pykM⁺) (JEP31) in minimal medium, minimal medium containing 55 mM glucose, and minimal medium containing 55 mM glucose and 55 mM pyruvate. The data represent the means and standard deviations from three separate cultures for each strain under each experimental condition examined in a single experiment. This experiment was repeated three times with the same results.
