Supplementary Figure 1. Growth rates of strains used in this study. The OD600 of planktonic cells growing in FAB containing 30 mM glutamate was measured for 14 hours. WT, green circles; ∆pslD, blue triangles; ∆pilA, black squares. Error bars represent standard deviation of three experiments. Results show that the growth rates are essentially identical
