title: The purple photosynthetic sulfur bacteria of genus Chromatium, isolated from lakes Yavorivske (Lviv region) and Sakske (AR Crimea)
abstract: The photosynthetic purple sulfur bacteria were isolated from lakes Yavorivske (Lviv region) and Sakske (AR Crimea). The purple sulfur bacteria use reduced sulfur compounds as electron donors for anoxygenic photosynthesis. The elemental sulfur produced by these microorganisms as intermediate in the oxidation of thiosulfate or hydrogen sulfide to sulfate. The bacteria strains Ya 2008/С and Sa 2008 / D with highest intracellular sulfur content have been choose for next investigation. Their morphoph
