Products of abiotic U(VI) reduction by biogenic magnetite and vivianite

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani, Jonathan Sharp, Daniel Scott Alessi

Reductive immobilization of uranium by the stimulation of dissimilatory metal-reducing bacteria (DMRB) has been investigated as a remediation strategy for subsurface U(VI) contamination. In those environments, DMRB may utilize a variety of electron accepto ...

Uranium speciation and stability after reductive immobilization in sediments

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani, Jonathan Sharp

It has generally been assumed that the bioreduction of hexavalent uranium in groundwater systems will result in the precipitation of immobile uraninite (UO2). In order to explore the form and stability of uranium immobilized under these conditions, we intr ...

Non-uraninite products of microbial U(VI) reduction

Elena Suvorova Buffat, Rizlan Bernier-Latmani, Harish Veeramani, Elena Cristina Dalla Vecchia, Jonathan Sharp, Nicholas Wigginton

A promising remediation approach to mitigate subsurface uranium contamination is the stimulation of indigenous bacteria to reduce mobile U(VI) to sparingly soluble U(IV). The product of microbial uranium reduction is often reported as the mineral uraninite ...

Comparative dissolution kinetics of biogenic and chemogenic uraninite under oxidizing conditions in the presence of carbonate

Rizlan Bernier-Latmani, Harish Veeramani, Jonathan Sharp

The long-term stability of biogenic uraninite with respect to oxidative dissolution is pivotal to the success of in situ bioreduction strategies for the subsurface remediation of uranium legacies. Batch and flow-through dissolution experiments were conduct ...
