Abstract

The anionic requirement for the oxidation of ferrous ions by suspensions of was satisfied by selenate as well as sulphate. Selenate was toxic to the organism and suppressed growth in ferrous iron media, even in the presence of high concentrations of sulphate. After treatment with dilute hydrochloric acid at 0°C, , which specifically required SO or SeO for iron oxidation, showed no activity in response to 12 other anions tested. However, after the introduction of SO or SeO , addition of anions such as TeO , WO , AsO or PO further enhanced the rate of iron oxidation. Under these conditions, Cl, BO and ClO had no significant effect at low concentration, whereas Br, NO and MoO were inhibitory. These observations distinguish between a specific and a non-specific anionic requirement for the oxidation of ferrous ions by . The specific requirement is satisfied only through the uptake of SO or SeO by the bacteria. The non-specific requirement is satisfied by any one of several anions, including SO and SeO , which are presumed to act as ligands for iron in solution.
