Extended Data Fig. 3: Nitric oxide shows a strong inhibitory effect.
From: Inhibition of phototrophic iron oxidation by nitric oxide in ferruginous environments
Time series of Fe(II) oxidation by R. ferrooxidans SW2 in the presence of different concentrations of nitric oxide. When 99% of Fe(II) is oxidized, bottles display characteristic orange colouration of Fe(III) minerals. Delays to iron oxidation are observed for all concentrations of NO although ultimately overcome by the end of the experiment up to 2.48 µM NO. Each bottle shown is a representative of the triplicates. Where the colour change in the triplicates varies considerably, all 3 bottles are shown as an insert.
