DescriptionRecently, some bacteria have been observed to grow when exposed to antimony but oxidation is not noted. No bacteria have been tested to grow on or oxidize bismuth. Both of these pnictogens, from group 15 on the periodic table, could support autotrophic growth by serving as an electron donor. Bosea sp. str. WAO is able to oxidize arsenic, the lightest metallic pnictogen, for autotrophic growth. Bosea sp. str. WAO was given different concentrations of antimony and bismuth in minimal media that would only stimulate autotrophic growth. Concentrations of the redox species of antimony and bismuth were measured by a modified antimony procedure and a novel colorimetric titration method to test for bismuth. The results showed a stoichiometric decrease in the reduced species of antimony and bismuth over time and an increase in the oxidized species. The concentration of Bosea sp. str. WAO was observed to increase when either antimony or bismuth had been present, showing that both antimony and bismuth could be used for autotrophic growth.
