α-Ketoglutarate Accumulation Is Not Dependent on Isocitrate Dehydrogenase Activity during Tellurite Detoxification in Escherichia coli

Figure 4

Total ROS and superoxide levels in tellurite-exposed E. coli. The indicated E. coli strains, exposed or not to tellurite, were assessed by flow cytometry to determine ROS as described in methods. ((a) and (b)): total ROS in LB-or M9-grown cells, respectively. ((c) and (d)): Superoxide levels in LB-or M9-grown cells, respectively. Numbers are the mean of 3 independent trials. *Significant regarding controls.
