Research summary<br />
The Extremophiles group has different research projects in<br />
which the main objectives are the following:<br />
Acidophilia: molecular ecology, molecular biology and<br />
biotecnology of microorganisms <strong>de</strong>veloping in acidic<br />
environments, with special emphasis in their potential<br />
applications: biohydrometallurgy, coal bio<strong>de</strong>sulfurization,<br />
specific metal sequestering, phytoremediation.<br />
Microbial ecology of terrestrial extreme environments as<br />
mo<strong>de</strong>ls of interest in astrobiology: geomicrobiology of the<br />
Tinto River Basin (Mars analog) and the hypersaline ponds<br />
from la Mancha (Europa analogs). This work is done in<br />
collaboration with the laboratory of Extremophiles of the<br />
Centro <strong>de</strong> Astrobiología (CSIC-INTA).<br />
Microbial molecular ecology of anaerobic environments:<br />
I) Characterization of the microbiota of marine sediments and<br />
<strong>de</strong>nitrifying reactors and its respective implication in the<br />
anaerobic <strong>de</strong>gradation of alkylbencene sulfonate (LAS) and in<br />
the elimination of NO3 - y H2S/S2O3 2- (autotrophic <strong>de</strong>nitrification).<br />
II) Methanogenesis of unusual environments. III) Anaerobic<br />
<strong>de</strong>gradation of xenobionts (LAS, organochlori<strong>de</strong>s).<br />
Harmful algal blooms: I) Development of molecular<br />
methodologies for the <strong>de</strong>tection of microalgae producing<br />
diarrhetic shellfish poisoning (DSP) or paralytic shellfish<br />
poisoning (PSP), II) Isolation and characterization of<br />
bacteria associated to toxic and non-toxic strains of<br />
Alexandrium minutum, a producer of paralytic shellfish<br />
poisoning (PSP); Posible biotechnological interest. III) Study<br />
of the genetic variability of Dinophysis spp.<br />
