Reduction of Soluble Iron and Reductive Dissolution of Ferric Iron-Containing Minerals by Moderately Thermophilic Iron-Oxidizing Bacteria [PDF]
Applied and Environmental Microbiology, 1998 ABSTRACT Five moderately thermophilic iron-oxidizing bacteria, including representative strains of the three classified species ( Sulfobacillus thermosulfidooxidans , Sulfobacillus acidophilus , and Acidimicrobium ferrooxidans ), were shown to be capable of ...

Microbial-Driven Stabilisation of Archaeological Iron Artefacts
Corrosion and Materials Degradation, 2021 The instability of iron artefacts is rooted in salt contamination during burial and damages associated with exposure to alternative oxygen levels and high relative humidity once excavated.

Evidence for suboxic nitrification in recent marine sediments [PDF]
, 2002 The classical scheme of biogeochemical zones (BGZ) is known to be an oversimplification of the microbial processes that occur in organic-rich marine sediments.

ChemElectroChem, 2023 Geobacter bacteria produce conductive pili appendages and an outer membrane‐anchored lipopolysaccharide to immobilize uranium extracellularly. Yet, some radionuclide enters the cell envelope, where is rapidly mineralized by periplasmic c‐cytochromes.

On Thermodynamics of Iron Reduction from Oxides
Steel in Translation, 2021 A computer simulation of the chemical process of direct iron reduction in aggregates was performed with the use of MIDREX technology. The analysis of four variants of this technology, which differ in the type of raw material and temperature of the working process, was carried out.

How many metals does it take to fix N2? A mechanistic overview of biological nitrogen fixation [PDF]
, 2006 During the process of biological nitrogen fixation, the enzyme nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Nitrogenase consists of two component metalloproteins, the iron (Fe) protein and the molybdenum-iron (MoFe) protein;

Reduction behavior of iron in the red mud
Journal of Mining and Metallurgy, Section B: Metallurgy, 2021 Red mud or bauxite residue contains significant quantities of industrial metals such as Fe, Al, and Ti, as well as rare earth elements such as Sc, Ce, and La. The authors performed a laboratory-scale project dealing with stepwise recovery of valuable elements from two bauxite residues, namely Iranian red mud (IRM) and Turkish red mud (TRM).

Microorganisms, 2020 The ectomycorrhizal fungus Paxillus involutus decomposes proteins using a two-step mechanism, including oxidation and proteolysis. Oxidation involves the action of extracellular hydroxyl radicals (•OH) generated by the Fenton reaction.

Magnetic Excitations of Undoped Iron Oxypnictides [PDF]
, 2009 We study the magnetic excitations of undoped iron oxypnictides using a three-dimensional Heisenberg model with single-ion anisotropy. Analytic forms of the spin wave dispersion, velocities, and structure factor are given.
