WebAnoxygenic phototrophic bacteria can be important primary producers in some meromictic lakes. Green sulfur bacteria (GSB) have been detected in ferruginous lakes, with some evidence that they are photosynthesizing using Fe(II) as an electron donor (i.e., photoferrotrophy). However, some photoferrotrophic GSB can also utilize reduced sulfur … WebThen they described the two main models that consider photoferrotrophy and O 2 produced by photosynthetic bacteria. Czaja et al. reported in 2024 [ 10 ] on the hematite–magnetite–pyrite Algoma-type iron formation of the 2.75 Ga Wilgie Mia Formation in the Weld Range of the Yilgarn craton, Australia.
