Radionuclide Reduction by Anaeromyxabacter dehalogenans


EMSL Project ID
18597

Abstract

The genus Anaeromyxobacter was described only recently, and members of this group appear to be major contributors to the biogeochemical cycling of metals. We demonstrated that Anaeromyxobacter dehalogenans strain 2CP-C efficiently reduces U(VI) to U(IV), and that strain 2CP-C captures energy from the reduction and grows with U(VI) as respiratory electron acceptor. Anaeromyxobacter species were found at uranium-contaminated sites, and appear to be a relevant organism contributing to U(V) reduction and immobilization in environmental settings. The proposed work will shed light on the cellular localization of reduced U(IV), and provide important information for further exploration of the biomolecular mechanisms contributing to U(VI) reduction.
