Anoxygenic photosynthesis is a bacterial photosynthesis that occurs under anaerobic conditions, using the photosynthetic electron transport chain in a noncyclic mode and reduced inorganic electron donors, such as hydrogen sulfide, hydrogen, or ferrous ion, as electron donors. There are also cases of anaerobic photosynthetic electron transport chains acting cyclically; in this case, the generation of reducing power is not needed or it is decoupled from the photosynthetic reaction. The prototypical noncyclic anoxygenic photosynthesis is present in green bacteria.
