Bacterial Colonization on the Surface of Copper Sulfide Minerals Probed by Fourier Transform Infrared Micro-Spectroscopy

open access: yesCrystals, 2020
Biofilm formation is a molecular assembly process occurring at interfaces, such as in bioleaching processes. The real time monitoring of the marker bands of amide I/amide II by FTIR microspectroscopy during Acidithiobacillus ferrooxidans colonization on ...

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

open access: yesInternational 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.

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.

Molybdenum Oxidation by Thiobacillus ferrooxidans [PDF]

open access: yesApplied and Environmental Microbiology, 1992
Thiobacillus ferrooxidans AP19-3 oxidized molybdenum blue (Mo 5+ ) enzymatically. Molybdenum oxidase in the plasma membrane of this bacterium was purified ca. 77-fold compared with molybdenum oxidase in cell extract.

A Trend‐Based Two‐Stage Framework for Tin (Sn) Recovery From Waste PCBs via Bioleaching and Thermally Activated Bentonite Adsorption

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
This study proposes a two‐stage, trend‐based framework for tin (Sn) recovery from waste printed circuit boards (PCBs) by integrating Acidithiobacillus ferrooxidans–mediated bioleaching with thermally activated bentonite adsorption. Bioleaching performance was optimized using a central composite design–based response surface methodology (CCD‐RSM), which

Sulfide oxidation by spheroplasts of Thiobacillus ferrooxidans [PDF]

open access: yesApplied and Environmental Microbiology, 1978
Thiobacillus ferrooxidans is an acidophilic organism important to metal leaching of low-grade ores. The aforementioned importance is related to the ability of the bacterium to oxidize reduced iron and sulfur, principally found in nature as pyrite (FeS2).

Newly Isolated Acidithiobacillus sp. Ksh From Kashen Copper Ore: Peculiarities of EPS and Colloidal Exopolysaccharide

open access: yesFrontiers in Microbiology, 2020
A novel strain of an iron- and sulfur-oxidizing bacterium was isolated from a natural biotope at Kashen copper ore (Martakert Province, Republic of Artsakh). The strain is able to grow and oxidize ferrous ions in the range of pH 1.4–2.6 with optimal pH 2.
