Figure 4. Sensitivity assays of the C. glutamicum WT(pXMJ19-His6-mtr) and WT(pXMJ19) strains against heavy metals.

Figure 4

(A–D) Growth (A600) of the C. glutamicum WT(pXMJ19) and WT(pXMJ19-His6-mtr) strains after 24 h at 30 °C in LB medium containing increasing concentrations of Cd2+ (A), Ni2+ (B), Cr6+ (C), and Co2+ (D) was recorded. Mean values with standard deviations (error bars) from at least three independent experiments are shown. *P ≤ 0.05. **P ≤ 0.01.
