TLDR
The newly observed bacterial process may significantly contribute to ferric iron formation in the suboxic zone of aquatic sediments.Abstract:
Enrichment and pure cultures of nitrate-reducing bacteria were shown to grow anaerobically with ferrous iron as the only electron donor or as the additional electron donor in the presence of acetate. The newly observed bacterial process may significantly contribute to ferric iron formation in the suboxic zone of aquatic sediments.read more

Cell biology and molecular basis of denitrification.
TL;DR: Denitrification is intimately related to fundamental cellular processes that include primary and secondary transport, protein translocation, cytochrome c biogenesis, anaerobic gene regulation, metalloprotein assembly, and the biosynthesis of the cofactors molybdopterin and heme D1.

Microorganisms pumping iron: anaerobic microbial iron oxidation and reduction
TL;DR: Biological iron apportionment has been described as one of the most ancient forms of microbial metabolism on Earth, and as a conceivable extraterrestrial metabolism on other iron-mineral-rich planets such as Mars.

Bacterial Manganese and Iron Reduction in Aquatic Sediments
TL;DR: The importance of bacteria in the biogeochemical manganese and iron cycles has gained broad appreciation over the past decade, and a large number of bacteria have been isolated that grow with oxidized Mn or Fe as sole terminal electron acceptor.
