· Iron acts as both a source and sink of electrons for microorganisms in the environment. Some anaerobic bacteria use oxidized Fe(III) as an electron acceptor, whereas phototrophic bacteria can use reduced Fe(II) as an electron donor. Byrne et al. show that the iron-bearing mineral magnetite, which contains both Fe(II) and Fe(III), can serve as both an …
