Abstract
En las últimas décadas, se ha intensificado el descubrimiento de ambientes extremos y de los organismos que los habitan, ampliando el conocimiento sobre cómo funciona la vida tanto en la Tierra como fuera de ella. Aunque los extremófilos incluyen miembros de los tres dominios de la vida, arquea, bacteria y eucariota, se ha desarrollado un gran interés hacia las bacterias que viven en ecosistemas extremos con el propósito de entender las estrategias de supervivencia únicas evolucionadas por estos organismos extremófilos y usarlas para desarrollar aplicaciones biotecnológicas. Entre las bacterias extremófilas, tienen interés especial las bacterias xerotolerantes o resistentes a la desecación, que son capaces de perder casi toda el agua al sufrir estrés hídrico, pero recuperar sus funciones normales tras la rehidratación...
