Membrane lipid peroxidation products were determined as thiobarbituric acid-reactive substances (TBARS) in wild type (BW25113) and ΔbtuE strains in the absence (control) or presence of K2TeO3 (0.5 µg ml−1) or H2O2 (100 µM) for 30 min. Values represent the mean of three independent experiments ± SD.
