Photocatalytic decomposition of hydrogen sulfide (H2S) into hydrogen (H2) by using the stratified type photocatalyst is considered as efficient route for the conversion of natural energy (solar energy) into clean energy (H2) . This reaction obeyed to next formula; 2HS-→2H+ + S22- + 2e-→H2↑+ S22-. To construct the continuous system, effective conversion route from S22-ion into H2S gas should be developed. In other word, sulfur cycle system should be constructed.<BR>In this report, conversion route from sulfur compounds (elemental sulfur and Na2SO4) into H2S by utilizing biological reaction was studied. H2S gas was stably synthesized until c.a.5% in the case of elemental sulfur addition, while it was c.a. 2% in the case of Na2SO4. Rate of biological reaction was seriously decreased if concentration of H2S was over these values because of its toxicity. Conversion efficiency was higher in the case of elemental sulfur addition since impediment of sodium ion was not progressed.
