Iron (III)‐uptake mechanisms in bacteria indigenous to the Antarctic, which is the most Fe‐
deficient continent on Earth, have not been extensively studied. The cold‐adapted, Antarctic …

Shewanella oneidensis strain MR-1 is a dissimilatory metal-reducing bacterium frequently
found in aquatic sediments. In the absence of oxygen, S. oneidensis can respire …

The availability of the complete genome sequence for Shewanella oneidensis MR-1 has
permitted a comprehensive characterization of the ferric uptake regulator (Fur) modulon in …

We developed a new method to measure iron reduction at a distance based on depositing
Fe (III)(hydr) oxide within nanoporous glass beads. In this “Fe-bead” system, Shewanella …

Iron is a vital element for life. However, after the Great Oxidation Event, the bioavailability of
this element became limited. To overcome iron shortage and to scavenge this essential …

Identification of the proteins directly involved in microbial metal-reduction is important to
understanding the biochemistry involved in heavy metal-reduction/immobilization and the …

Shewanella oneidensis MR-1 respires a wide range of anaerobic electron acceptors,
including sparingly soluble Fe (III) oxides. In the present study, S. oneidensis was found to …

Abstract Background Iron homeostasis of Shewanella oneidensis, a γ-proteobacterium
possessing high iron content, is regulated by a global transcription factor Fur. However …

Siderophores are small-molecule high-affinity multidentate chelators selective for ferric iron
that are produced by pathogenic microbes to aid in nutrient sequestration and enhance …

The work in this thesis expands the knowledge of the ways in which S. oneidensis interacts
with Fe 2+, including its uptake and efflux, and presents a potential mode of Fe 2+ toxicity …
