title: Geomicrobiological aspects of the oxidation of reduced sulfur compounds by photosynthesizing bacteria.
abstract: The activity of photosynthesizing sulfur bacteria in a continuous culture was studied. The bacteria were isolated from the natural environment with the use of the Winogradski column. Isolated bacteria were cultured in synthetic medium and in the effluent from the column containig HS-. Sulphides, the main product of reduction of sulfates in phosphogypsum, were used by green sulfur bacteria in the photosynthetic column. Almost 70% reduction of the concentration of sulfides was observed. After the experiment, diffractometric methods where employed to analyze the sediment from the column.
