Figure 2. Effects of Mtr overexpression on oxidants and alkylating agents-induced oxidative stresses resistance in C. glutamicum.

Survival of the C. glutamicum WT(pXMJ19) and WT(pXMJ19-His₆-mtr) strains after challenging with various oxidants including H₂O₂ (100 mM), diamide (10 mM), CHP (11 mM), MD (4 mM), and formaldehyde (20 mM), and different alkylating agents containing CDNB (70 mM), NEM (16 mM), IAM (40 mM), and MG (10 mM) for 30 min. Mean values with standard deviations (error bars) from at least three independent experiments are shown. n.s.: not significant. *P ≤ 0.05. **P ≤ 0.01.
