Ferric reduction by Thiobacillus ferrooxidans and Thiobacillus thiooxidans when grown on an elemental sulfur medium was studied. Ferric iron served as an oxidant for elemental sulfur oxidation, but not as an electron acceptor for respiration. The reduction was a nonenzymatic process, although ferric iron reduction was parallel to the cell growth during elemental sulfur oxidation. It is suggested that reduction is mainly dependent on some reducing substrates produced during the growth period.
