Figure 3-11. The effects of various CN-B12 concentrations on the growth of strain BE182
          (ApduA) and the wild type strain (S. enterica). Cells were cultured on PD
          minimal medium supplemented with CN-B12 at the concentrations indicated.
          Wild-type, (U); BE182 (ApduA) (@). Error bars represent one standard
          deviation. OD600, optical density at 600nm.
