Figure 2. Oxidative stress sensitivity of a S. aureus ΔcymR mutant.
Viability of SA6 (SH1000/pMK4), SA30 (ΔcymR/pMK4) and SA31 (ΔcymR/pDIA5780) was tested. Exponential-phase cells grown in TSB medium with 2 mM cystine were treated for 1 h with 20 mM H2O2 and plated on BHI. Results represent the mean values for survival with standard deviations and are representative of at least two independent experiments.
