FIGURE 4. — Growth and iron reduction characterization of wild type and ΔSO2907. Panel A, growth curve of wild type (filled symbols) and ΔSO2907 (open symbols) under aerobic conditions with LB (triangles, left axis) or anaerobically with fumarate as the TEA (circles, right axis). The fumarate growth medium contained 30 mm lactate and 50 mm fumarate. Panel B, growth curve (circles) and Fe³⁺ reduction (triangles) of wt (filled symbols) and ΔSO2907 (open symbols) growing anaerobically with citrate-Fe³⁺ as the TEA. The growth medium contained 30 mm lactate and 50 mm citrate-Fe³⁺. Panel C, growth curve (circles) and Fe³⁺ reduction (triangles) of wt (filled symbols) and ΔSO2907 (open symbols) growing anaerobically with 10 mm goethite as the TEA. Experiments (except for the cell counts of panel C) were performed in triplicates. Data were represented as mean ± S.D.
