    • Bioinformatic prediction and experimental verification of Fur-regulated genes in the extreme acidophile ... 
      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 ...
    • The ferric iron uptake regulator (Fur) from the extreme acidophile Acidithiobacillus ferrooxidans 
      Quatrini, Raquel; Lefimil, Claudia; Holmes, David S.; Jedlicki Corbeaux, Eugenia (SOC GENERAL MICROBIOLOGY, 2005-06)
      Acidithiobacillus ferrooxidans is a Gram-negative bacterium that lives at pH 2 in high concentrations of soluble ferrous and ferric iron, making it an interesting model for understanding the biological mechanisms of bacterial ...
    • Insights into the iron and sulfur energetic metabolism of Acidithiobacillus ferrooxidans by microarray ... 
      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 ...
    • Iron homeostasis strategies in acidophilic iron oxidizers: Studies in Acidithiobacillus and Leptospirillum 
      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 ...
    • Microarray and bioinformatic analyses suggest models for carbon metabolism in the autotroph Acidithiobacillus ... 
      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 ...
