“…Briefly, 80 mM FeSO 4 solution (250 mL) was inoculated with A. ferrooxidans resting cell (6 × 10 7 cells mL –1 ) and co-cultured for 5 days at an initial pH of 2.5 and 180 rpm (28 °C). , At a given time interval, 2 mL of suspension was withdrawn and determined for pH, Fe 2+ , total Fe, and SO 4 2– after filtering through a 0.45 μm membrane. The resultant precipitate was collected by vacuum filtration and then washed three times with H 2 SO 4 solution (pH = 2.0) and deionized water, respectively.…”

Schwertmannite, ubiquitously found in iron and sulfate-rich acid mine drainage, is generated via biological oxidation of ferrous ions by Acidithiobacillus ferrooxidans (A. ferrooxidans). However, little information on the mechanisms of biogenic schwertmannite formation and crystal growth is available. This study deliberately investigated the relationships among mineral morphology, solution chemistry, and phase transformation of schwertmannite in A. ferrooxidans-containing ferrous sulfate solutions. The formation of schwertmannite could be divided into three stages. In the first nucleation stage, crystallites are presented as nonaggregative or aggregative forms via a successive polymerization process. In the second stage, ellipsoidal aggregates, which are identified as ferrihydrite and/or schwertmannite, are formed. In the third stage, needles appear on the surface of ellipsoidal aggregates, which is caused by the phase transformation of ferrihydrite or schwertmannite to lepidocrocite and goethite through a Fe 2+ (aq) catalysis-driven pathway. After three stages, a typical characteristic "hedgehog" morphology finally appears. In addition, A. ferrooxidans could significantly speed up the mineral transformation. Solution pH affects the morphology of schwertmannite by acid leaching. The experimental results also reveal that the formation of schwertmannite depend on the content of hydroxyl complexes or the transformation of the monomers to polymers, which are greatly affected by the solution pH.

“…Jarosite is able to synthesize in the presence of some ions including Cr(III), Hg(II), Pb(II) under certain temperature and pH in solution, since it is insoluble in a dilute acid environment and easy to precipitate (Daoud et al 2006). The synthesis rate of jarosite catalyzed by A. ferrooxidans (increase in the oxidation rate of Fe(II)) was found to be faster than that by chemical synthesis (Wang et al 2019;Guay et al 1977). It has been documented that the biosynthesized jarosite has some specific traits such as uniform dispersive crystal structure and smooth profile (Henao et al 2010).…”

“…It has been reported that schwertmannite synthesized by A. ferrooxidans can degrade methyl orange (Zhang et al 2018). The biosynthetic schwertmannite can exhibit a high catalytic efficiency at a neutral environment with a pH of 7.5, which can overcome the disadvantage of a narrow pH range for a homogeneous fenton reaction (Wang et al 2019). The catalytic degradation of methyl orange by biosynthetic schwertmannite can still be carried out under a high concentration of nitrate, sulfuric acid and chloride ions (Xiang Li et al 2018).…”

Biological materials formed by Acidithiobacillus ferrooxidans and their potential applications

et al. 2020

A variety of biological materials including schwertmannite, jarosite, iron-sulfur cluster (ISC) and magnetosomes can be produced by Acidithiobacillus ferrooxidans (A. ferrooxidans). Their possible formation mechanisms involved in iron transformation, iron transport, and electron transfer were proposed. The schwertmannite formation usually occurs under the pH of 2.0-3.51, and a lower or higher pH will promote jarosite to be produced. Available Fe 2+ in the environment and the carrier proteins that can transport Fe 2+ to the intracellular membranes of A. ferrooxidans play a critical role in the synthesis of magnetosomes and ISC. The potential applications of these biological materials were reviewed, including removal of heavy metal by schwertmannite, detoxification of toxic species by jarosite, the transference of electron and ripening the iron sulfur protein by ISC, and biomedical application of magnetosomes. Additionally, some perspectives for the molecular mechanisms of synthesis and regulation of these biomaterials were briefly described.

Synthesis of Isotopically Labelled Disparlure Enantiomers and Application to the Study of Enantiomer Discrimination in Gypsy Moth Pheromone‐Binding Proteins

To study the binding mechanism of disparlure (7,8)‐epoxy‐2‐methyloctadecane enantiomers with pheromone‐binding proteins (PBPs) of the gypsy moth, oxygen‐17 or 18 and 5,5,6,6‐deuterium labelled disparlure enantiomers were prepared in an efficient, enantioselective route. Key steps involve the asymmetric α‐chlorination of dodecanal by SOMO catalysis and Mitsunobu inversion of a 1,2‐chlorohydrin. The pheromone, (+)‐disparlure (7R, 8S), was tested in two infested zones, demonstrating that it is very attractive towards male gypsy moths. Studies of the binding of (+)‐disparlure and its antipode to gypsy moth PBPs by 2H &17O NMR at 600 MHz are reported. Chemical shifts, spin‐lattice relaxation decay times (T1) and transverse relaxation decay times (T2) of deuterium atoms of disparlure enantiomers in 2H NMR show that the binding of disparlure enantiomers to PBP1 differs from binding to PBP2, as expected from their opposite binding preferences (PBP1 binds (–)‐disparlure, and PBP2 binds (+)‐disparlure more strongly). Models of the disparlure enantiomers bound to one internal binding site and two external binding sites of both PBPs were constructed. The observed chemical shift changes of deuterated ligand signals, from non‐bound to bound, T1 and T2 values are correlated with results from the simulations. Together these results suggest that the disparlure enantiomers adopt distinct conformations within the binding sites of the two PBPs and interact with residues that line the sites.
