WebJan 15, 2024 · In the ferruginous and anoxic early Earth oceans, photoferrotrophy drove most of the biological production before the advent of oxygenic photosynthesis, but its association with ferric iron (Fe3 ... WebNov 5, 2024 · Photoferrotrophy is a form of anoxygenic photosynthesis whereby bacteria utilize soluble or insoluble forms of ferrous iron as an electron donor to fix carbon dioxide using light energy. They can also use poised electrodes as their electron donor via phototrophic extracellular electron uptake (phototrophic EEU). The electron uptake … WebPhotoferrotrophy: anoxygenic phototrophic bacteria . Authors for literature search: Konhauseretal, Hiesing et al, 1998, 1999. Leptothrix is a well know genus that oxidizes FeII, (These are not photosynthetic. Many of the other Fe oxidzers are photosynthetic.) They produce sheaths, and are motile by way of flagella. chiot manche
