Biogeochemical iron (Fe) cycling in pH-circumneutral environments involves concurrent microbially and chemically driven ferrous iron (Fe(II)) oxidation and Fe(III) reduction processes, which must be ...
Bacteria have sensitive and specific sensors — involving redox-active cofactors such as haem, flavins, pyridine nucleotides and iron–sulphur clusters, or redox-sensitive amino-acid side chains such as ...
