... of Geobacter sulfurreducens and the bioprecipitated uranium phases. Our results reveal the association between nutrient uptake and precipitation of uranium minerals. Biosequestration of uranium is enhanced by addition of nutrients such as acetic acid, and uranium is precipitated on the surface of the bacteria...

... Geobacter sulfurreducens . With increasing vanadium in the ferrihydrite, the amount of V-doped magnetite produced decreased due to V-toxicity which interrupted the reduction pathway ferrihydrite–magnetite, resulting in siderite or goethite formation. Fe L 2,3 and V L 2,3 X-ray absorption spectra and data...
