Reduction of uranium by Desulfovibrio desulfuricans

Article Abstract:

The ability of Desulfovibrio desulfuricans to precipitate soluble uranium was investigated. The results showed that D. desulfuricans can rapidly reduce soluble uranium to insoluble form. The reduction process appears to be a direct reaction. However,D. desulfuricans did not grow in the presence of soluble uranium as the sole electron acceptor. The results suggest that sulfate reducers play an important role in uranium and sulfide deposition in land and marine environments. The useof these microorganisms in the decontamination of uranium-contaminated waters may be possible.

Growth of strain SES-3 with arsenate and other diverse electron acceptors

Article Abstract:

The bacterial strain SES-3 may be able to reduce and grow in the presence of electon acceptors such as arsenate, sulfur, nitrite, Mn(IV), trimethylamine N-oxide and fumarate. As SES-3 grows it is able to reduce arenate to arsenite, Fe(III) to Fe(II), and thioosulfate to sulfide. These reductions are useful in converting environmental pollutants, such as arsenic, into less toxic forms.

Benzene oxidation coupled to sulfate reduction

Article Abstract:

Analysis of the anaerobic oxidation of benzene under sulfate-reducing conditions supports the function of sulfur as principal electron acceptors during benzene oxidation. Isotope trapping experiments reveal that sulfate reducers completely oxidize benzene to CO2 without generating extracellular intermediates.
