Oxygen uptake coupled with uranous sulfate oxidation bythiobacillus ferrooxidansandT. Acidophilus

Abstract
The oxidation of uranous compounds by washed cell suspensions of T. ferrooxidans and T. acidophilus was monitored with a Clark oxygen electrode. The bacteria were able directly to oxidize U-IV, which was supplied as uranous sulfate or as uranous oxide. The rates of O2 uptake were dependent on the cell concentration, the previous growth history of the organisms, the amounts of U-IV and of inhibitors, pH and the presence of iron sulfates.
