“…Previous studies have shown that FecA1, FeoAB and MntH are responsible for Fe(II) uptake, and some genes including tonB, exbB and exbD (moreover PorA protein family) involve in Fe(III) transfer in A. ferrooxidans (He et al 2020). The uptake of Fe(II) and Fe(III) is the most crucial stage for magnetosome synthesis because of the requirement of a large amount of iron to biomineralize magnetosomes in A. ferrooxidans.…”

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.
