FIG. 2.

(A) H₂O₂ survival test of N. gonorrhoeae strain 1291 wild type (WT) and laz mutant. In this assay, cells were grown on BHI agar ± 100 μM MnSO₄ and exposed to 40 mM H₂O₂. (B) H₂O₂ survival test of N. meningitidis strain MC58 wild type (WT) and laz mutant. In this assay, cells were grown on BHI agar and exposed to 10 mM or 15 mM H₂O₂. Experiments were performed in triplicate. The y axis error bars indicate ±1 standard deviation of the mean.
