The purpose of this investigation was to determine the effect of bacterial oxidation of sulfur upon the release of soluble manganese from manganese dioxide. Using the soil perfusion technique it was found that the oxidation of elemental sulfur or sodium thiosulfate applied to soil resulted in a release of soluble manganese accompanied by a lowering of pH. Addition of calcium carbonate caused a decrease in the amount of soluble manganese released, although the amount of sulfate formed was not changed significantly. In pure culture studies on synthetic media, 10 times more soluble manganese was found when sulfur was oxidized by Thiobacillus thiooxidans than when the same acidity was produced by the addition of sulfuric acid. Separation of the MnO 2 from the sulfur and the bacteria by a collodion membrane did not prevent the reduction of manganese.
