forms ranging from poorly- to highly-ordered oxides. The structure, composition
and degree of crystallinity of these minerals vary greatly depending on the physical
and chemical conditions of their surroundings. The transformation of Fe (hydr)
oxides under microbial Fe(III)-reducing and chemical Fe(II)-oxidizing conditions is
well characterized. However, Fe(II) oxidation in anaerobic environments by bacteria
that couple Fe(II) oxidation to nitrate reduction remains poorly understood.
Linking geochemical processes to changes in microbial community composition
and activity is crucial for revealing the fate of nitrogen and carbon in soils and
sediments, and elucidating key biogeochemical features that govern nitrate-dependent
Fe(II) oxidation.
