Figure 1. NrdAB and NrdEF are both functional during protracted H2O2 stress.

Figure 1

Cells were pre-cultured in anaerobic glucose/aromatic medium and then diluted at time zero into the same aerobic medium. Viability was tracked by anaerobic plating. (A) Cell viability during routine aerobic growth. MG1655 (wild type), JEM84 (ΔnrdAB), JEM89 (ΔnrdEF), and JEM118 (ΔnrdAB ΔnrdEF). (B) Viability during protracted H2O2 stress (ca. 0.5 μM). LC106 (Hpx−), JEM86 (Hpx−ΔnrdAB), JEM90 (Hpx−ΔnrdEF), and JEM119 (Hpx−ΔnrdAB ΔnrdEF).
