Abstract

The thermophilic, gram-positive bacterium Thermoterrabacterium ferrireducens coupled organotrophic growth to the reduction of sparingly soluble U(VI) phosphate. X-ray powder diffraction and X-ray absorption spectroscopy analysis identified the electron acceptor in a defined medium as U(VI) phosphate [uramphite; (NH₄)(UO₂)(PO₄) · 3H ₂O], while the U(IV)-containing precipitate formed during bacterial growth was identified as ningyoite [CaU(PO₄)₂ · H₂O]. This is the first report of microbial reduction of a largely insoluble U(VI) compound.
