Variations in activities of sewer biofilms due to ferrous and ferric iron dosing.

Addition of ferrous and ferric iron salts to wastewater is a commonly used practice for sulfide abatement in sewer force mains. When iron is added to wastewater where sulfate respiration takes place, it produces ferrous sulfide precipitates with the formed sulfide. The effect of iron addition has traditionally been focused on solely from the perspective of reaction stoichiometry. Possible influences on the microbial communities in biofilms growing in force mains have largely been neglected. In this study th...


Administration of ferrous sulfate drops has significant effects on the gut microbiota of iron-sufficient infants: a randomised controlled study.

DMT1 and Iron Transport.

Many past and recent advances in the field of iron metabolism have relied upon the discovery of divalent metal transporter 1, DMT1 in 1997. DMT1 is the major iron transporter and contributes non-heme iron uptake in most types of cell. Each DMT1 isoform exhibits different expression patterns in cell-type specificity and distinct subcellular distribution, which enables cells to uptake both transferrin-bound and non-transferrin-bound irons efficiently. DMT1 expression is regulated by iron through the translati...

Toward a mechanistic understanding of Feo-mediated ferrous iron uptake.

Virtually all organisms require iron and have evolved to obtain this element in free or chelated forms. Under anaerobic or low pH conditions commonly encountered by numerous pathogens, iron predominantly exists in the ferrous (Fe2+) form. The ferrous iron transport (Feo) system is the only widespread mechanism dedicated solely to bacterial ferrous iron import, and this system has been linked to pathogenic virulence, bacterial colonization, and microbial survival. The canonical feo operon encodes for three p...

Tropolone-induced effects on the unfolded protein response pathway and apoptosis in multiple myeloma cells are dependent on iron.

Tropolones are naturally occurring seven-membered non-benzenoid aromatic compounds that are of interest due to their cytotoxic properties. MO-OH-Nap is a novel α-substituted tropolone that induces caspase cleavage and upregulates markers associated with the unfolded protein response (UPR) in multiple myeloma (MM) cells. Given previous reports that tropolones may function as iron chelators, we investigated the effects of MO-OH-Nap, as well as the known iron chelator deferoxamine (DFO), in MM cells in the pr...

The Ins and Outs of Iron: Escorting Iron through the Mammalian Cytosol.

Mammalian cells contain thousands of metalloproteins and have evolved sophisticated systems for ensuring that metal cofactors are correctly assembled and delivered to their proper destinations. Equally critical in this process are the strategies to avoid the insertion of the wrong metal cofactor into apo-proteins and to avoid the damage that redox-active metals can catalyze in the cellular milieu. Iron and zinc are the most abundant metal cofactors in cells and iron cofactors include heme, iron-sulfur clust...

Kinetics of sulfide precipitation with ferrous and ferric iron in wastewater.

Traditionally, sulfide abatement has been done by adding e.g. ferrous or ferric iron salts to the start of sewer force mains. Iron dosage must hence correspond to an estimate of how much sulfide will form while the wastewater stays in the main, which is not straightforward. Adding iron salts at the end of the main has the advantage that the exact amount of sulfide to precipitate, in principle, can be known. A drawback is that the reaction time is short compared to start-of-pipe treatment. Sulfide precipitat...

Homology modelling of human divalent metal transporter (DMT): Molecular docking and dynamic simulations for duodenal iron transport.

Iron transport through the duodenum is regulated by carrier proteins, one of which is the ubiquitously distributed divalent metal transporter (DMT1) which is responsible for the uptake of iron across the apical surface of the duodenal enterocyte. The crystallographic structure of Staphylococcus capitis divalent metal ion transporter (ScaDMT1) was obtained and it was used as a template for the construction of a homology model of human divalent metal transporter (hDMT1). The binding site for hDMT1 was determi...

Direct evidence for ferrous ions oxidation and incorporation in absence of oxidants by Dps from Marinobacter hydrocarbonoclasticus.

Dps (DNA-binding protein from starved cells) proteins are hollow sphere shaped, dodecameric enzymes found in bacteria and archaeal species. They are able to oxidize ferrous iron in a controlled manner using hydrogen peroxide or molecular oxygen as co-substrate and most of them confer physical protection through DNA binding. Oxidized iron is stored, as a mineral core, in a central cavity. In this study, we provide direct evidence that, in addition to these activities, Dps proteins containing small mineral co...

Sulfate removal from acid mine water from the deepest active European mine by precipitation and various electrocoagulation configurations.

Sulfate removal from mine or process water is a key issue in the mining industry. In this paper, precipitation with lime (calcium oxide) was integrated with electrocoagulation for sulfate removal from Pyhäsalmi/Finland mine water. Sulfate precipitation with calcium oxide decreased the sulfate concentration from 13,000 mg/L to 1600 mg/L. Various current densities were applied to the pre-treated mine water with various electrodes and aluminium and iron anodes. It was found that 25 mA/cm was the best te...

Altered chemistry of oxygen and iron under deep Earth conditions.

A drastically altered chemistry was recently discovered in the Fe-O-H system under deep Earth conditions, involving the formation of iron superoxide (FeOHx with x = 0 to 1), but the puzzling crystal chemistry of this system at high pressures is largely unknown. Here we present evidence that despite the high O/Fe ratio in FeOHx, iron remains in the ferrous, spin-paired and non-magnetic state at 60-133 GPa, while the presence of hydrogen has minimal effects on the valence of iron. The reduced iron is ac...

Favourable improvement in haematological parameters in response to oral iron and vitamin C combination in children with Iron Refractory Iron Deficiency Anemia (IRIDA) phenotype.

Treatment in IRIDA focuses on use of intravenous iron preparations to circumvent oral absorptive defect resulting from high levels of hepcidin due to TMPRSS6 gene variations. However, recent case reports and recommendations on atypical microcytic hypochromic anemias advocate use of oral iron and vitamin c trial before parenteral iron, as the same results in comparable improvement in haemoglobin. We prospectively evaluated our IRIDA cohort (n = 7) with oral iron and vitamin c dose over a period of 10 w...

Vivianite as the main phosphate mineral in digested sewage sludge and its role for phosphate recovery.

Phosphate recovery from sewage sludge is essential in a circular economy. Currently, the main focus in centralized municipal wastewater treatment plants (MWTPs) lies on struvite recovery routes, land application of sludge or on technologies that rely on sludge incineration. These routes have several disadvantages. Our study shows that the mineral vivianite, Fe(PO) × 8HO, is present in digested sludge and can be the major form of phosphate in the sludge. Thus, we suggest vivianite can be the nucleus for...
