The growth of phototrophic sulfur bacteria Pelochromatium roseo-viridae under the influence of different heavy metals` salts concentrations was investigated. The repression of the bacteria growth after metals` salts addition into medium was shown. Qualitative and quantitative composition of basic photosynthetic pigments in cells under these conditions was determined.
