Growth of wild-type DC3000 and mqo::KO in culture. Wild-type DC3000 and the mqo::KO mutant were grown in HS media with a 10 mM concentration of the indicated carbon source: citrate (a), succinate (b), and malate (c and d). Similar results were obtained for at least two additional independent experiments. In panels a, c, and d, three replicate cultures were used for each growth curve, and the error bars represent the standard deviation of the mean. In panel b, each time point represents a single sample.
