Nitrate had no effect on bacterial aerobic Sb(III) oxidation. (A) Sb(III) oxidation profiles of Sinorhizobium sp. GW3 with the addition of 20 μM Sb(III) and different concentrations of nitrate under oxic conditions. Sb(V) concentrations in the culture fluids were measured using HPLC-HG-AFS. (B) Nitrite production by strain GW3 during the process of aerobic Sb(III) oxidation. Nitrite concentrations in the culture fluids were measured using HPLC. Error bars represent standard deviations of the means from three independent experiments.
