The anoxygenic photosynthetic purple bacteria

Abstract

Modern systematics of phototrophic purple bacteria is described. Their distribution and living conditions based on literature data and original research data are shown. The morphological characteristics, pigments composition and photosynthesis particularies are described. Participation of these bacteria in the natural sulfur cycle, the ways of their hydrogen sulphide usage are shown. The areas of practical application of purple phototrophic bacteria are pointed.
