Just hit me that (it true) this would have preceded the first of life’s known major change to the environment, the Great Oxidation Event. So not only once but twice in an early era life totally disrupted the “normal” surroundings and caused utter chaos for existing life, which had to adapt to a new world. Next question, would these bacteria have been the same culprits?
anaerobic metabolism of photoferrotrophic bacteria
Suggests no? Because the great oxidation was caused by the development of photosynthesis as used in chlorophil. Staring at this page on iron-oxidizing bacteria, none of the key reactions have elemental oxygen as a by-product. Definitely not an expert, could be reading this wrong.

You did more research than I did, so more of an expert than me. Sounds like you’re correct.
