Molecular Characterization of Copper and Cadmium Resistance Determinants in the Biomining Thermoacidophilic Archaeon Sulfolobus metallicus
(Hindawi, 2013)
Sulfolobus metallicus is a thermoacidophilic crenarchaeon used in high-temperature bioleaching processes that is able to grow
under stressing conditions such as high concentrations of heavy metals. Nevertheless, the genetic ...
Response of the biomining Acidithiobacillus ferrooxidans to high cadmium concentrations
(Elsevier B.V., 2019)
© 2018 Elsevier B.V. Cadmium is a heavy metal present in contaminated soils. It has no biological role but when entering cells generates DNA damage, overexpression of stress response proteins and misfolded proteins, amongst ...
Co-occurrence interaction networks of extremophile species living in a copper mining tailing
(Frontiers Media, 2022)
Copper mining tailings are characterized by high concentrations of heavy metals and an acidic pH, conditions that require an extreme adaptation for any organism. Currently, several bacterial species have been isolated and ...
A DNA segment encoding the anticodon stem/loop of tRNA determines the specific recombination of integrative-conjugative elements in Acidithiobacillus species
(Taylor and Francis, 2018)
Horizontal gene transfer is crucial for the adaptation of microorganisms to environmental cues. The
acidophilic, bioleaching bacterium Acidithiobacillus ferrooxidans encodes an integrative-conjugative
genetic element ...
Insights into the iron and sulfur energetic metabolism of Acidithiobacillus ferrooxidans by microarray transcriptome profiling
(ELSEVIER, 2006-09)
Acidithiobacillus ferrooxidans is a well known acidophilic, chemolithoautotrophic, Gram negative, bacterium involved in bioleaching and acid mine drainage. In aerobic conditions, it gains energy mainly from the oxidation ...
High copper concentration reduces biofilm formation in Acidithiobacillus ferrooxidans by decreasing production of extracellular polymeric substances and its adherence to elemental sulfur
(Elsevier, 2020)
Acidithiobacillus ferrooxidans is an acidophilic bacterium able to grow in environments with high concentrations of metals. It is a chemolithoautotroph able to form biofilms on the surface of solid minerals to obtain its ...
Biooxidación de concentrados de arsenopirita por acidithiobacillus ferrooxidans en erlenmeyer agitados
(Universidad Nacional de Colombia, 2012)
Título en ingles: Biooxidation of arsenopyrite concentrates by Acidithiobacillus ferrooxidans in shake flasks Resumen Se evaluó el proceso de biooxidación de concentrados de arsenopirita por A. ferrooxidans ATCC 23270, ...
Comparación del potencial oxidativo de Acidithiobacillus ferrooxidans, en un proceso de biodesulfurización de carbón
(Universidad Nacional de Colombia - Sede Bogotá - Instituto de Biotecnología, 2016-01-01)
En este estudio se comparó la actividad oxidativa de dos cepas de Acidithiobacillus ferrooxidans en un proceso de desulfurización, empleando un carbón sub-bituminoso alto en azufre (2.30% de azufre total, con 1.06% pirítico, ...
Nanoparticles in fossil and mineral fuel sectors and their impact on environment and human health: A review and perspective
