(Springer, 2013)Attachments of Acidithiobacillus ferrooxidans ATCC 23270 onto elemental sulfur, quartz and complex chalcopyrite were investigated by analysis of its extracellular polymeric substances as well as applying Langmuir and ...
-
(Springer, 2020)Objective This study aims to investigate the attachment of Acidithiobacillus ferrooxidans to pyrite in two different environments: fresh and saline water (water with 35 g/L of NaCl or 0.6 M). Adsorption isotherms were ...
-
(MDPI, 2021)Acidithiobacillus ferrooxidans has been shown to be a good depressant of pyrite in freshwater and seawater flotation. However, the effect of these bacteria over copper-activated pyrite has not been studied. At the industrial ...
-
(2013)The biomining bacterium Acidithiobacillus ferrooxidans oxidizes sulfide ores and promotes metal solubilization. The efficiency of this process depends on the attachment of cells to surfaces, a process regulated by quorum ...
-
(Universidad de Chile, 2009)El presente trabajo de título tiene por objetivo el estudio de la biolixiviación de pirita por un cultivo puro de Acidithiobacillus ferrooxidans y por un consorcio de cepas nativas provenientes de la solución lixiviante ...
-
(universidad de chile, 2006)El "Quorum Sensing" (QS) es un sistema de comunicacion bacteriana que controla la expresion de ciertos genes en funcion del tanafio poblacional. Existen varios tipos de sistemas de QS. El sistema mds generalizado en ...
-
(Universidad de Chile, 2018)Acidithiobacillus ferrooxidans es una bacteria quimiolitoautótrofa, acidófila, involucrada en un consorcio bacteriano capaz de biolixiviar metales como el cobre. Este microorganismo posee la capacidad de vivir en ambientes ...
-
(Universidad de Chile, 2007)La oxidación bacteriana del ión ferroso con Acidithiobacillus ferrooxidans en presencia de carbón activado es un proceso útil tanto para la generación de ión férrico como para la generación de inóculos de alta concentración ...
-
(Universidad de Chile, 2017-06-28)La chaperona bacteriana periplasmática CusF es parte del sistema de resistencia a cobre CusCFBA. CusF une cobre (I) en el periplasma bacteriano mediante una histidina y dos metioninas muy conservadas en las bacterias. ...
-
(Springer, 2012)Acidithiobacillus ferrooxidans is a chemolithoautotrophic acidophilic bacterium that obtains its energy from the oxidation of ferrous iron, elemental sulfur, or reduced sulfur minerals. This capability makes it of great ...
-
(SPRINGER HEIDELBERG, 2005-12)Commercial bioleaching of copper and the biooxidation of gold is a cost-effective and environmentally friendly process for metal recovery. A partial genome sequence of the acidophilic, bioleaching bacterium Acidithiobacillus ...
-
(2016)Acidithio bacillus ferrooxidans is used in industrial bioleaching of minerals to extract valuable metals. A. ferrooxidans strain ATCC 53993 is much more resistant to copper than other strains of this microorganism and it ...
-
(Frontiers Research Foundation, 2011)Production of sulfur globules during sulfide or thiosulfate oxidation is a characteristic feature of some sulfur bacteria. Although their generation has been reported in Acidithiobacillus ferrooxidans, its mechanism of ...
-
(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 ...
-
(2016)While a functional quorum sensing system has been identified in the acidophilic chemolithoautotrophic Acidithiobacillus ferrooxidans ATCC 23270T and shown to modulate cell adhesion to solid substrates, nothing is known ...
-
(MDPI AG, 2018)© 2018 by the authors. Licensee MDPI, Basel, Switzerland. Acidithiobacillus ferrooxidans resists extremely high concentrations of copper. Strain ATCC 53993 is much more resistant to the metal compared with strain ATCC ...
-
(Academic Press Inc., 2010)Glutamyl-tRNA synthetases (GluRS) provide Glu-tRNA for different processes including protein synthesis, glutamine transamidation and tetrapyrrole biosynthesis. Many organisms contain multiple GluRSs, but whether these ...
-
(Universidad de Chile, 2014)In the first chapter, this thesis aims to demonstrate the great potential of Constraint-Based Reconstruction and Analysis (COBRA) methods for studying and predicting specific phenotypes in the bacterium Acidithiobacillus ...
