[Physilogical and biochemical properties of bacteria of Chromatium genus, isolated from water bodies enriched with hydrogen sulfide].
Pure cultures of purple sulfur bacteria, which were attributed to genus Chromatium, were isolated from water bodies of the Yavoriv sulfur deposit. Both cultures perform anoxygenic photosynthesis and contain bacteriochlorophyll a and carotenoids of spirilloxanthin group. Isolated bacteria grow photolithoauthotrophically, photolithoheterotrophically and photoorganoheterotrophically. Hydrogen sulphide, sulfur and thiosulfate were used as inorganic electron donors. Bacteria were resistant to high hydrogen sulphide concentrations and assimilated it effectively in the process of anoxygenic photosynthesis. Isolated bacteria are considered as promising models for creation of biotechnologic ecosystems, which will be used for treatment of media polluted with sulfur compounds.
