1) The optimal pH of the sulfur oxidation on T. thiooxidans was about 3,and some considerable activity was also observed between 5.0 and 7.3. 2) Thiosulfate was utilized only at pH below 5. The evidence for the formation of tetrathionate as an intermediate in the oxidation of thiosulfate at pH 4.5 was obtained by the washed cells. 3) The pH optimum for the oxidation of tetrathionate by the washed cells was at from 2 to 3,and the activity fell markedly at pH above 3.5. The quantitative oxidation of tetrathionate to sulfate was achieved with freshly harveste cells. 4) Sodium α-glycerophosphate was oxidized by either the washed cells or the cell-free extracts of T. thiooxidans. 5) Paper chromatographys of inorganic sulfur compounds were established.
