Effects of H₂O₂ on the growth of acI strains. Various concentrations of pyruvate (0 to 50 μM) (A, B, E, and F) and H₂O₂ (0 to 10 μM) (C, D, G, and H) were added to the basal media containing hemin (10 nM) and riboflavin (1 nM) to adjust the hydrogen peroxide concentration of the media. (A–D) Growth of IMCC25003 (A and C) and IMCC26103 (B and D). (E–H) Changes in H₂O₂ concentration during cultivation of IMCC25003 (E and G) and IMCC26103 (F and H). All experiments were performed in triplicate. Error bars indicate the SE. Note that error bars shorter than the size of the symbols are hidden.
