A bacterial isolate, strain FMn 1, from reservoir sediment oxidized Mn 2+ when tested in growing culture and resting‐cell suspension. The oxidation was biologically mediated and not the result of autoxidation because at a MnSO 4 · H 2 O concentration of 0.05%. The pH remained below 7.5 for the duration of the experiments. The productions of manganese oxide was qualitatively and quantitatively demonstrated. Teh manganese‐oxidizing activity of this organism was found to be inducible.
