Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the

Cloning of a Thiobacillus ferrooxidans plasmid in Escherichia coli [PDF]

Journal of Bacteriology, 1984
Three separate plasmids of 6, 7, 16, and greater than 23 kilobases were purified from a single clone of Thiobacillus ferrooxidans ATCC 33020 grown in the presence of uranium. The 6.7-kilobase plasmid (pTf1) was cloned separately into the HindIII or BamHI site of Escherichia coli plasmid pBR322.

The role of surface properties of Thiobacillus Ferrooxidans and minerals in microbial adhesion [PDF]

Acta Montanistica Slovaca, 2001
To explain the selective microbial adhesion of Thiobacillus ferrooxidans on pyrite, zeta potential of both the bacterium cells and the mineral was measured using the electrophoretic light scattering (ELS) technique.

Selective Adhesion of Thiobacillus ferrooxidans to Pyrite [PDF]

Applied and Environmental Microbiology, 1993
Bacterial adhesion to mineral surfaces plays an important role not only in bacterial survival in natural ecosystems, but also in mining industry applications. Selective adhesion was investigated with Thiobacillus ferrooxidans by using four minerals, pyrite, quartz, chalcopyrite, and galena.
