Microorganisms as potential vectors of the migration of radionucleides
Yves Andrès1, 2, S. Redercher, G. Thouand

The migration of heavy metals and radionuclides depends on many factors of which the microbiological life. In this paper, we describe in a first step, the microorganisms-metals interaction processes and secondly, our works on biosorption. The important factors affecting the biosorption are the cell wall structure and the growth conditions. Bacteria are shown to exhibit a fixation selectivity for some ions (Th4+). Finally we give some examples of the characterization of the binding sites.
