FIG. 2.

Growth curves of the S. enterica serovar Typhimurium wild-type strain 14028 in MM without or with increasing concentrations of MI. The iolD2 and iolE deletion mutants were cultivated in the presence of 55.5 mM MI. Zero growth of the wild-type strain and the two mutants in the absence of this carbon source was monitored for at least 100 h after inoculation. Standard deviations from at least three independent experiments are shown. The molarity of MM with respect to MI is indicated. WT, wild type.
