Toxicity of membrane filters toThiobacillus ferrooxidans
Zeitschrift für allgemeine Mikrobiologie, 1971AbstractMembrane filters of different origins and types contain substances that are toxic to Thiobacillus ferrooxidans in media where Fe2+ constitutes the source of energy. The toxic principle(s) can be almost completely removed by heating to 115–120 °C or by leaching in boiling water.

Stability of copper tolerance inThiobacillus ferrooxidans
Antonie van Leeuwenhoek, 1994A strain of Thiobacillus ferrooxidans MAL-4-1 was adapted to grow at higher concentrations of copper by repeated subculturing in the presence of increasing levels of added cupric ions in 9K medium. The strains adapted to copper were found to be more efficient in bioleaching of copper from concentrates.

[Thiobacillus ferrooxidans pili].
Mikrobiologiia, 1978The surface structures of Thiobacillus ferrooxidans were studied. When growing on a medium containing elemental sulphur, the cells possess peritrichously located filaments (piles) whose diameter varies from 4.5 to 7.0 nm and length, from 0.7 to 3.0 mcm. The cells of T. ferrooxidans do not have piles on a medium with ferrous iron. The physiological role

Hydrometallurgy, 1999
The question whether the overall bacterial oxidation rate of a pyrite is determined by both the chemical reactivity of the pyrite as well as the affinity of a bacterial strain to the ferrous to ferric iron ratio, was examined. Bioleaching studies were carried out with a pure culture of Thiobacillus ferrooxidans and an enrichment culture of ...

Although Thiobacillus ferrooxidans and Leptospirillum ferrooxidans are widely considered to be the microorganisms that control the rate of generation of acid mine drainage, little is known about their natural distribution and abundance.

Volatilization of mercury byThiobacillus ferrooxidans
Current Microbiology, 1981Thiobacillus ferrooxidans became significantly more tolerant to mercury stress after culturing in media of increasing mercury(II) concentrations. When mercuric chloride was added to the growth medium, the resistant organisms were found to volatilize elemental mercury (Hg0).T.
