Actinide Interactions with Bacteria


Actinide Interactions with Bacteria

Moll, H.; Bernhard, G.

Microbes are widely distributed in nature also under harsh conditions (e.g., high salinity; low permeability; high and low temperatures). They can strongly influence the migration of hazardous actinides in the environment once they have been released. This is demonstrated by an increased interest in studies exploring the interaction processes involving actinides and bacteria during the last years. However, worldwide only little detailed information is available about the biodiversity and microbial influences on radionuclide migration under the conditions of a deep nuclear repository.
The presentation covers the broad topic of actinide interactions with bacteria. A short overview about the determination of the microbial diversity giving the dominant bacterial strains will be given. In more detail, the manifold interaction process of bacteria with actinides will be highlighted based on selected examples.
With this presentation we want to point out the importance of actinide-microbe interactions for the disposal of nuclear waste.

Keywords: microbes; actinides; nuclear waste disposal
