Expression of a Thiobacillus ferrooxidans origin of replication in Escherichia coli [PDF]

Journal of Bacteriology, 1984
A cryptic plasmid from an autotrophically grown arsenic-resistant strain of Thiobacillus ferrooxidans was isolated and cloned into pBR325. The origin of replication of pBR325 was deleted, and the recombinant plasmid was shown to replicate in Escherichia coli, using an origin of replication located on the Thiobacillus plasmid.

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Biological ferrous sulfate oxidation by A. ferrooxidans immobilized on chitosan beads [PDF]

Journal of Microbiological Methods, 2008
The immobilization of Acidithiobacillus ferrooxidans cells on chitosan and cross-linked chitosan beads and the biooxidation of ferrous iron to ferric iron in a packed-bed bioreactor were studied. The biofilm formation was carried out by using a glass column reactor loaded with chitosan or cross-linked chitosan beads and 9 K medium previously inoculated

Review and Integrated Framework for Deep‐Sea Mineral Resources, Ecological Influence, and Future Development

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
As global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

A new solid medium for isolating and enumerating Thiobacillus ferrooxidans.

The Journal of General and Applied Microbiology, 1989
The growth of seven Thiobacillus ferrooxidans strains was trested on various solid media prepared according to previously published procedures in comparison with a series of new formulations (TSMs, Thiobacillus solid media) set up in our laboratory. These media differed in the type of gelling agent and in the concentration of phosphate and ferrous ions.
