Iron-reducing bacteria accumulate ferric oxyhydroxide nanoparticle aggregates that may support planktonic growth

Assessing Mutualism Between Dissimilatory Ferric Iron- and Sulfate-Reducing Bacteria

Ferric oxyhydroxide microparticles in water

Mineralogy and specific surface area are major controls on the stabilities of ferric oxyhydroxide microparticles in natural waters. The thermodynamic stabilities of ferric oxyhydroxides, as described by the activity product in solution pK = -log [Fe(3+)] [OH(-)](3) range from pK = 37.1 for freshly precipitated amorphous oxyhydroxide to pK = 44.2 for well crystallized goethite. The sizes of susp...

Ferric iron reduction by acidophilic heterotrophic bacteria.

Fifty mesophilic and five moderately thermophilic strains of acidophilic heterotrophic bacteria were tested for the ability to reduce ferric iron in liquid and solid media under aerobic conditions; about 40% of the mesophiles (but none of the moderate thermophiles) displayed at least some capacity to reduce iron. Both rates and extents of ferric iron reduction were highly strain dependent. No a...

iron-reducing bacteria and iron nanostructures

iron reducing bacteria (irb) are one of the most applicable microorganisms in various industrial and environmental activities. these bacteria play a main role in the natural iron transformation. they act in a reverse metabolic pathway in contrast to iron oxidizing bacteria. in the anaerobic conditions irb are capable to use ferric ion as the final electron acceptor and reduce fe3+ to fe2+. what...
