Eight strains of Thiobacillus ferrooxidans and three strains of Thiobacillus were grown on ferrous iron (Fe{sup 2+}), elemental sulfur (S{sup 0}), or sulfide ore (Fe, Cu, Zn). The cells were studied for their aerobic Fe{sup 2+} and S{sup 0}-oxidizing activities (O{sub 2} consumption) and anaerobic S{sup 0}-oxidizing activity with ferric iron (Fe{sup 3+}) (Fe{sup 2+} formation). Results show that all the T. ferrooxidans strains studied have the ability to produce cells with Fe{sup 2+} and S{sup 0} oxidation and Fe{sup 3+} reduction activities, but their levels are influenced by growth substrates and strain differences.
