Growth impairment of the mutant strains. The AE104 (closed circles), ΔzupT (open circles), Δ7 (open squares), Δ8 (open triangles), Δ7 mgtA::kan (open inverted triangles), and Δ9 (open diamonds) strains were cultivated in TMM at 30°C without further additions (A) or in the presence of 10 µM Zn(II) (B), 10 µM Co(II) (C), or 2.5 µM Cd(II) (D), and growth was measured as turbidity at 600 nm (n ≥ 3). Standard deviations are indicated by bars.
