Continuous-feed, mixed carbon medium chemostat culture of ΔptsG mutant cells. At the indicated dilution rates samples were tested for (A) culture density (OD600nm), (B) cell buoyant density and (C) cell volume comparison; together with the consumption ratio (D), which is calculated as the ratio between individual substrate uptake rate and the total carbon uptake rate and for illustration purpose the glucose consumption ratio of wild type MG1655 cells from Figure 3C is also shown.
