Isolation and characterization of a genetically tractable photoautotrophic Fe(II)-oxidizing bacterium, Rhodopseudomonas palustris strain TIE-1
Article Abstract:
The isolation and characterization of a genetically tractable Fe(II)-oxidizing phototroph which differs from phototrophic ferrous iron [Fe(II)]-oxidizing bacterium TIE-1 that is closely related to the type strain of Rhodopseudomonas palustris is reported. It shows that TIE-1 grows photoautotrophically with Fe(II), H2 or thiosulfate as the electron donor, photoheterotrophically with a variety of organic carbon sources and chemoheterotrophically in the dark.

Shewanella oneidensis MR-1 uses overlapping pathways for iron reduction at a distance and by direct contact under conditions relevant for biofilms
Article Abstract:
A new method to measure iron reduction at a distance based on depositing microbial iron [Fe(III)] (hydr)oxide within nanoporous glass beads is developed. It shows that CymA and menaquinone are required for both direct and indirect mineral reduction, whereas MtrB and OmcB contribute to but are not absolutely required for iron reduction at a distance.

Phenazines and other redox-active antibiotics promote microbial mineral reduction
Article Abstract:
The microbial reductive dissolution of minerals significantly affects the chemistry of soils as they make iron more easily available to plants. Studies suggest phenazines and other redox-active antibiotics are capable of promoting microbial mineral reduction.
