Desulfovibrio baarsii
Desulfovibrio
sulfodismutans
The reduction of U(VI) resulted in the precipitation of uraninite. No reduction appeared to
conserve enough energy to support growth.
[122]
Desulfovibrio vulgaris
Desulfovibrio
sp.
This bacterium was capable of growing by reducing U(VI): it detoxified U(VI) and
obtained energy
via
nitrate reduction.

Desulfovibrio desulfuricans
U(VI) was reduced with lactate or pyruvate as the electron donor.
[126]
Geobacter metallireducens
Dissimilatory Fe(III)-reducing bacteria obtained energy for growth by electron transport to
U(VI).
[41, 34]
Geobacter sulfurreducens
The reduction of U(VI) associated with surfaces of synthetic hydrous ferric oxide, goethite,
and hematite was comparable to the reduction of aqueous U(VI). The reduction of U(VI)
adsorbed to natural Fe(III) oxide-bearing solids was slower and less extensive compared
to that of synthetic Fe(III) oxide systems. The addition of anthraquinone-2,6-disulfonate
enhanced U(VI) reduction.
[111]
Pseudomonas putida
Resting cells anaerobically reduced U(VI) with lactate as the electron donor. A slightly
higher reduction was observed under aerobic conditions with glucose as the electron
donor. Reduced uranium accumulated both on the surface and internally.
[39]
Pyrobaculum islandicum
U(VI) was reduced with hydrogen as the electron donor. The reduction was dependent upon
the presence of cells and hydrogen.
