[Sulfate-reducing bacteria in reservoirs of the Yavoriv sulfur field].

Fifteen cultures of bacteria which perform dissimilation sulfate reduction have been isolated from the reservoirs of the Yavoriv sulfur deposit. Electron-microscopic investigations have shown that the cells of all cultures are of vibroid, spiral and bacillary form. They form no spores. They grow in the medium with sulfates and lactates and do not use propionate and acetate. In the medium with lactate all the cultures accumulated acetate in the medium. Cells of all the studied bacteria contain desulfoviridine. On the basis of obtained characteristics the isolated bacteria are referred to genus Desulfovibrio.
