FIG. 3.

E_corr (A), relative corrosion rate per unit area (A) (1/R_p · A, expressed in ohms⁻¹ · centimeter⁻²) (B), and ferrous iron concentration (C) in solution as a function of exposure time. The data are from a 5-day static incubation experiment in which we compared the behavior of the wild type (□) to the behavior of the fliI mutant (◊), the menC mutant (○), and an uninoculated control (▵). The data are representative of the data obtained in five independent experiments for each strain or control.
