Abstract
The effect of hydrogen peroxide (H202) on growth and respiration of Thiobacillus thiooxidans and Thiobacillus ferrooxidans, organisms involved in acid leaching of copper sulfide minerals and uarnium oxides, was examined. Oxygen uptake and growth by T. thiooxidans were totally inhibited after contact with 0.82 mM H202. Complete inhibition of oxygen uptake by T. ferrooxidans occurred at 8.75 mM H202, and growth was inhibited after 6 hr exposure to 2.06 mM H202. Higher concentration of H202 can be used without detriment to thiobacilli if it is dissipated prior to reaching the oxidation pond or dump surface.
