Lefimil, Claudia; Jedlicki Corbeaux, Eugenia; Holmes, David S. (Elsevier, 2012)Reporter gene assays are important tools for evaluating gene expression. A frequently used assay measures the activity of b-galactosidase (b-gal) expressed from lacZ in plasmid or genomic constructions. Such constructions ...

Brasseur, G.; Levicán, Gloria; Bonnefoy, Violaine; Holmes, David S.; Jedlicki Corbeaux, Eugenia; Lemesle Meunier, D. (ELSEVIER, 2004-06-07)Acidithiobacillus ferrooxidans is an acidophilic chemolithoautotrophic bacterium that can grow in the presence of either the weak reductant Fe2+, or reducing sulfur compounds that provide more energy for growth than Fe2+. ...

Barreto, Marlen; Quatrini, Raquel; Bueno, Susan; Arriagada, Claudia; Valdés, Jorge; Silver, Simon; Jedlicki Corbeaux, Eugenia; Holmes, David S. (ELSEVIER SCIENCE, 2003-10)Candidate genes have been identified in the almost complete genome sequence of Acidithiobacillus ferrooxidans that are potentially involved in several physiological processes of relevance to the application of this ...

Quatrini, Raquel; Lefimil, Claudia; Veloso, Felipe A.; Pedroso, Inti; Holmes, David S.; Jedlicki Corbeaux, Eugenia (2007)The gamma-proteobacterium Acidithiobacillus ferrooxidans lives in extremely acidic conditions (pH 2) and, unlike most organisms, is confronted with an abundant supply of soluble iron. It is also unusual in that it oxidizes ...

Quatrini, Raquel; Jedlicki Corbeaux, Eugenia; Holmes, David S. (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 ...

Barreto, Marlen; Jedlicki Corbeaux, Eugenia; Holmes, David S. (AMER SOC MICROBIOLOGY, 2005-06)A cluster of five genes, proposed to be involved in the formation of extracellular polysaccharide (EPS) precursors via the Leloir pathway, have been identified in the acidophilic autotroph Acidithiobacillus ferrooxidans. ...

Quatrini, Raquel; Appia Ayme, Corinne; Denis, Yann; Ratouchniak, Jeanine; Veloso, Felipe A.; Valdés, Jorge; Lefimil, Claudia; Silver, Simon; Roberto, Frank; Orellana Orellana, Omar; Denizot, François; Jedlicki Corbeaux, Eugenia; Holmes, David S.; Bonnefoy, Violaine (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 ...

Osorio, Héctor; Martínez, Verónica; Veloso, Felipe A.; Pedroso, Inti; Valdés, Jorge; Jedlicki Corbeaux, Eugenia; Holmes, David S.; Quatrini, Raquel (Elsevier B.V., 2008-11)An understanding of the physiology and metabolic complexity of microbial consortia involved in metal solubilization is a prerequisite for the rational improvement of bioleaching technologies. Among the most challenging ...

Appia Ayme, Corinne; Quatrini, Raquel; Denis, Yann; Denizot, François; Silver, Simon; Roberto, Francisco; Veloso, Felipe A.; Valdés, Jorge; Cárdenas, Juan; Esparza, Mario; Orellana Orellana, Omar; Jedlicki Corbeaux, Eugenia; Bonnefoy, Violaine; Holmes, David S. (ELSEVIER, 2006-09)Acidithiobacillus ferrooxidans is a chemolithoautotrophic bacterium that uses iron or sulfur as an energy and electron source. Bioinformatic analysis of the A. ferrooxidans draft genome sequence was used to identify putative ...
