A combination of Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy, Transmission Electron Microscopy (TEM) and Energy-Dispersive X -ray (EDX) was used to conduct a molecular and atomic analysis of the uranium complexes formed by A. ferrooxidans. The results demonstrated that this bacterium accumulates uranium as phosphate compounds. We hypothesize that the poly P-bodies of A. ferrooxidans may play a role in detoxification of those part of uranium which is uptaken by the cells.
