Steps of thiosulfate oxidation by Thiobacillus thioparus and Th. coproliticus.
Chromatographic analysis was used for studying steps of thiosulfate oxidation by Thiobacillus thioparus and Th. coproliticus strains, isolated from Egyptian soil. Th. thioparus strains oxidized S2O3 to SO4 with the formation of polythionates, tetrathionate in particular, during the course of oxidation. However, strains differed in other polythionates formed. Th. coproliticus, in turn, oxidized S2O3 to SO4 without polythionate formation. However, H2S was the only intermediate compound detected during oxidation.
