• 1. In the early stage of CO_2-fixation by Thiobacillus thiooxidans, which was incubated aerobically in the presence of sulfur, most part of the fixed carbon was found in the phosphate ester fraction. 2. The fixation was inhibited by NaF, picolinic acid, PCMB, azide, dipyridyl, o-phenanthroline, monoiodoacetic acid, and arsenite, each in the concentration range where the sulfur oxidation was not affected strongly. 3. The crude extract of this organism could fix CO_2 in the presence of ATP, R-5-P and Mg^<++>. Most part of the fixed carbon was found in PGA. 4. The crude extract showed the CO_2-fixation coupled with the H_2S-oxidation in the presence of ADP. 5. An appreciable reduction of PGA could not be detected in the presence of reducing systems, involving TPNH and DPNH.
