WebPhotolithotrophs obtain energy from light and therefore use inorganic electron donors only to fuel biosynthetic reactions (e. g., carbon dioxide fixation in lithoautotrophs). Lithoheterotrophs versus lithoautotrophs Lithotrophic bacteria cannot use, of course, their inorganic energy source as a carbonsource for the synthesis of their cells. WebElectron donors are H 2 (with the exception of some Hydrogenothermaceae species), elemental sulfur (S 0) or thiosulfate (S 2 O 32− ); electron acceptors are O 2 in the case of the microaerobic Aquificaceae and Hydrogenothermaceae (some organisms can also use NO 3− or S 0 ), whereas the strictly anaerobic Desulfurobacteriaceae only utilize sulfur … Web21 mrt. 2024 · Ferrous iron (Fe 2+) can be used as an electron donor by lithotrophic microbes in acidic, oxic environments where Fe 2+ is soluble and oxygen can serve as the terminal electron acceptor. This has been well characterized in the β-proteobacterium Acidithiobacillus ferrooxidans and thermophilic crenarchaeotes in the genus Sulfolobus. darcy drew carey show
