Pu interaction studies with a typical bacterial isolate from Mont Terri Opalinus clay

Nuclear waste is supposed to be stored in deep geological formations. An example is the Opalinus clay formation located in the North-Western part of Switzerland (Mont Terri URL) which is currently studied in terms of its suitability as host rock for future nuclear waste storage. In this talk, results will be presented and discussed describing the interactions of a specific novel Sporomusa sp. isolate with plutonium. Results from accumulation experiments as well as detailed plutonium oxidation state changes in the presence and absence of an electron donor will be discussed.
