DOIAbstract
<p>TEM images prepared from cell suspensions incubated with 250 μM uranyl acetate and 10 mM lactate for 24 h. The localization of UO<sub>2</sub> by MR-1 (A, B) was compared to OmcA<sup>−</sup> (C), MtrC<sup>−</sup> (D–F), and MtrC<sup>−</sup>/OmcA<sup>−</sup> (G, H). High-resolution image of extracellular UO<sub>2</sub> nanoparticles showing d-lines values consistent to previous patterns of biogenic and synthetic UO<sub>2</sub> (I). The UO<sub>2</sub>-EPS is designated by the arrows. Locations of the cell membrane (CM), periplasm (P), and outer membrane (OM) are shown. </p
