Extreme habitats as reservoir for unusual bacterial strains: Perspectives for bioremediation and nanotechnology


Extreme habitats as reservoir for unusual bacterial strains: Perspectives for bioremediation and nanotechnology

Merroun, M.

Microorganisms can mobilise radionuclides/metals through autotrophic and heterotrophic leaching, chelation by microbial metabolites and siderophores, and methylation, which can result in volatilisation. Conversely, immobilisation can result from sorption to cell components or exopolymers, intracellular sequestration or precipitation as insoluble organic and inorganic compounds. In this talk, we will present the last results about the spectroscopic and microscopic characterization of interaction mechanisms between radionuclides and bacterial strains isolated from extreme habitats, including uranium mining waste piles. Some of the isolated strains could be used as templates for the formation of metallic nanoparticles (Pd, Au).
