Abstract
The oxidation of elemental sulfur by Thiobacillus thiooxidans was studied a t pH 2.3, 4.5, and 7.0 in the presence of different concentrations of vario us anions (sulfate, phosphate, chloride, nitrate, and fluoride) and cations (potassium, sodium, lithium, rubidium, and cesium). The results agree with the expected response of this acidophilic bacterium to charge neutralizati on of colloids by ions, pH-dependent membrane permeability of ions, and osm otic pressure.
