Iron is a micronutrient for nearly all life on Earth. It can be used as an electron donor and electron acceptor by iron-oxidizing and iron-reducing microorganisms and is used in a variety of biological processes, including photosynthesis and respiration.

Livestock wastewater reused in farmland may cause tylosin to stay in farmland soil. Under the influence of some factors, such as irrigation and fertilization, tylosin may desorb and diffuse into the water environment.

Achieving Ammonium Removal Through Anammox-Derived Feammox With Low Demand of Fe(III)
Feammox-based nitrogen removal technology can reduce energy consumption by aeration and emission of carbon dioxide. However, the huge theoretical demand for Fe(III) becomes a challenge for the further development of Feammox.

Ferric iron reduction by sulfur- and iron-oxidizing bacteria [PDF]
Acidophilic bacteria of the genera Thiobacillus and Sulfolobus are able to reduce ferric iron when growing on elemental sulfur as an energy source. It has been previously thought that ferric iron serves as a nonbiological oxidant in the formation of acid mine drainage and in the leaching of ores, but these results suggest that bacterial catalysis may ...

Reduction of Soluble Iron and Reductive Dissolution of Ferric Iron-Containing Minerals by Moderately Thermophilic Iron-Oxidizing Bacteria [PDF]
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
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.

On Thermodynamics of Iron Reduction from Oxides
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.

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.

Little is known about the effects of bacterial community on iron (Fe) and phosphorus (P) cycles in sediments under different primary producer habitats in different seasons. Lake Taihu has both the cyanobacteria- and macrophyte-dominated lake zones.
