Fig. 2From: Disrupting ROS-protection mechanism allows hydrogen peroxide to accumulate and oxidize Sb(III) to Sb(V) in Pseudomonas stutzeri TS44Sb(III) oxidation in P. stutzeri strains TS44, TS44-gshA540 and TS44-gshA-C with the addition of 0.2Â mmol/L Sb(III). The amounts of Sb(III) and Sb(V) in culture fluids were calculated based on culture volume to normalize for the total amount of antimony added. Sb(III) and Sb(V) concentrations in the culture fluids were measured using HPLC-HG-AFS. Error bars correspond to the standard deviations of the means from three independent experimentsBack to article page
