Abstract. This work presents an overview of the
physicochemical and biological studies carried out along Rio Agrio and in
different hot springs belonging to the
geothermal Copahue volcano system, in Neuquén Argentina. This is an extreme
environment characterized by wide ranges of temperature, pH (<1 to 8) and
heavy metals concentration. In these extreme conditions chemolitho-autotrophic
bacteria, archaea, heterotrophic bacteria, yeasts and filamentous fungi were
detected. Members of Leptospirillum ferrooxidans, Acidithiobacillus
ferrooxidans, Acidithiobacillus thiooxidans and Acidianus spp.,
among others, were successfully cultivated and physiological properties of
different isolates were determined. Additionally, bioleaching and biooxidation
of regional ores were carried out using mixed native cultures.
