Figure 2From: Escherichia coli avoids high dissolved oxygen stress by activation of SoxRS and manganese-superoxide dismutaseGlucose-limited continuous culture of E. coli MG1655 at 30% and 300% dO 2 . (A) Biomass concentration, residual glucose and excreted acetate concentration (B) Volumetric oxygen uptake rate (QO2), carbon dioxide formation (QCO2) rate, and the respiratory quotient (RQ) profile. The arrow indicates when dO2 was increased from 30% to 300%.Back to article page
