To find an efficient bacterium, which has the strong capacity to produce hydrogen sulfide from polysulfide as the waste of process generating hydrogen from hydrogen sulfide by photocatalytic reaction using sun light, is very important for constructing hydrogen producing system. 10 strains of sulfate-reducing bacteria (SRB), which can reduce polysulfide directly, have been isolated from various natural samples such as TCE contaminated soil, soil and sludge around hot spring environment, and the cooling tower of a geothermal plant. This study describes physiological and phylogenetic characterization of SRB which can reduce polysulfide. All of isolates had the ability to reduce polusulfide but these reduction rates were difference depend on isolates. Phylogetetically, all of isolates located difference position for general SRB including Desulfovibrio desulfuricans, which is used standard strain in this study, so they do not belong to Proteobacteria. These have close relation to the genus Desulfotomaculum which can reduce elemental sulfur. It suggests that the ability of reducing elemental sulfur is important for reducing polysulfide to hydrogen sulfide.
