Diversidad microbiana en ambientes volcánicos

Abstract: El sistema Copahue-Caviahue, que comprende el Volcán Copahue, el Río Agrio, varias manifestaciones geotermales de distintas temperaturas además de lagunas, lagos y otros cursos de agua, es un ambiente natural de características principalmente termales y ácidas, derivadas de su origen volcánico. Estos hábitats están colonizados por microorganismos especialmente adaptados para sobrevivir en condiciones extremas, por lo que son denominados extremófilos. Los extremófilos participan activamente en la geoquímica del… Show more

“…Rio Agrio is one of the few naturally acidic rivers, Table 1 shows the main physicochemical characteristics of the sites analyzed in this study. The two geothermal sources of the river, VA1 and VA2, present pH values around 2, however they differ in temperature (VA1 41.0 • C and VA2 28.8 • C), something already observed in previous samplings [27]. The variation in temperature is probably related to the fact that VA2 is more exposed to the cold wind and the melting snow.…”
