Organization and Differentiation of Membranes of Phototrophic Bacteria

摘要: Publisher Summary It is generally accepted that phototrophic bacteria are recent representatives of an evolutionary ancient group living organisms. One the major arguments in favor this hypothesis fact all members perform anoxygenic photosynthesis. may be speculated acquisition tetrapyrrole synthesis enabled original forms these organisms to adapt aerobic energy metabolism employing cytochromes a respiratory chain with oxygen as electron acceptor. The chapter demonstrates photosynthetic apparatus several species localized intracytoplasmic membranes, whereas contained predominantly cytoplasmic membrane. This cytological compartmentation electron-transport chains cannot generalized. Although exhibit considerable metabolic versatilities, them largely restricted ecological niches providing anaerobic conditions. Overall, data reported demonstrate essential similarities well specific differences responses various toward changes environmental
