WebAnoxygenic phototrophic Fe(II)-oxidizing bacteria (photoferrotrophs) are suggested to have contributed to the deposition of banded iron formations (BIFs) from oxygen-poor seawater. However, most studies evaluating the contribution of photoferrotrophs to Precambrian Fe(II) oxidation have used freshwater and not marine strains.

Weborganic-rich shales, and fueled microbial methanogenesis. As a result, the deposition of BIFs by photoferrotrophs would have contributed fluxes of methane to the atmosphere and thus helped to stabilize Earth’s climate under a dim early Sun. INTRODUCTION Banded iron formations (BIFs) host the world’s largest iron ore WebInstead, it could result from the long-lasting ambient pressure of metabolically produced extracellular iron oxide minerals in photoferrotrophs together with the emergence of local oxygen oases. The presence of oxygen could favor cells with the ability to navigate into oxic-anoxic transition zones since the oxygen was entirely toxic to Archean ...
