Aqueous wastes from nuclear fuel reprocessing present special problems of radiotoxicity of the active species. Cells of Serratia sp. were found previously to accumulate high levels of hydrogen uranyl phosphate (HUP) via the activity of a phosphatase enzyme. Uranium is of relatively low radiotoxicity whereas radionuclide fission products such as 90Sr and 137Cs are highly radiotoxic. These radionuclides can be co‐crystallized, held within the bio‐HUP “host” lattice on the bacterial cells and… Expand
Uranium biomineralization induced by a metal tolerant Serratia strain under acid, alkaline and irradiated conditions.
This study establishes the ecological adaptation of a natural strain like Serratia in a uranium enriched environment and corroborates its contribution towards uranium immobilization in contaminated subsurfaces through the formation of stable uranyl phosphate minerals over a wide pH range. Expand
