The aim of our research is to investigate the peculiarities of metabolism of Green
Sulfur bacteria which are present in storage lakes, drain rivers, and reservoirs around
Yavoriv sulfur deposit. The major problem is hydrogen sulfide toxic water that permanently
fills the invalid sulfur quarry. According to our results, we assume that pure culture
of green sulfur bacteria is obtained. After identification we presume that we obtain
Pelodiction luteolum. The next tasks are: to investigate the nature of their pigments
using the cells that we selected, to investigate the special features of metabolism of the
selected cuture. These investigations will be useful for us as a key to solve Yavoriv
ecological problem, about purification of water from H2S.
