FIGURE 2: The inhibitory effect of DMB mimics that of a flavin antagonist. (A) Wild-type S. Typhimurium was grown in lysogeny broth with different concentrations of DMB or 3 mM of adenine. (B) Growth rates of S. Typhimurium grown in NCE minimal medium provided with different carbon sources and supplemented with different concentrations of DMB or diphenyliodonium chloride were calculated as described in Materials and Methods. Error bars represent standard deviation of three technical replicates and each experiment was performed thrice; a representative set of data are presented. Every data point has error bars, which if not shown it means the bars were smaller than the symbol.
