<strong>VIII</strong> <strong>Reunión</strong> <strong>de</strong> la Sociedad Mexicana <strong>de</strong> Astrobiología<br />
Cuernavaca, Morelos. 24 <strong>de</strong> agosto <strong>de</strong> 2012 91<br />
En la Tierra un ambi<strong>en</strong>te anóxico y sulfatado con la pres<strong>en</strong>cia <strong>de</strong> hidróg<strong>en</strong>o o material orgánico<br />
es habitable por PRS, si la temperatura <strong>de</strong>l océano <strong>de</strong> Europa ti<strong>en</strong>e la temperatura <strong>en</strong> el rango <strong>de</strong><br />
tolerancia <strong>de</strong> las PRS psicrófilas, las PRS psicrófilas son un objeto <strong>de</strong> interés astrobiológico. Exist<strong>en</strong><br />
datos que <strong>de</strong>scrib<strong>en</strong> el crecimi<strong>en</strong>to y la actividad <strong>de</strong> las PRS <strong>en</strong> bajas temperaturas que ayudarían a<br />
inferir la cantidad <strong>de</strong> ácido sulfhídrico resultante <strong>de</strong> su metabolismo <strong>en</strong> condiciones europanas para<br />
compr<strong>en</strong><strong>de</strong>r si la actividad biológica <strong>de</strong> las PRS sería <strong>de</strong>tectable.<br />
