In situ microbial reduction of soluble U(VI) to sparingly soluble U(IV) was evaluated at the site of the former S-3 Ponds in Area 3 of the U.S. Department of Energy Natural and Accelerated Bioremediation Research Field Research Center, Oak Ridge, TN. After establishing conditions favorable for bioremediation (Wu, et al. Environ. Sci. Technol. 2006, 40, 3988-3995), intermittent additions of ethanol were initiated within the conditioned inner loop of a nested well recirculation system. These…

Pilot-scale in situ bioremediation of uranium in a highly contaminated aquifer. 1. Conditioning of a treatment zone.

The effects of ethanol addition on in situ denitrification and U(VI) reduction and immobilization are described and the conditions were judged suitable for biostimulation.

In situ bioreduction of uranium (VI) to submicromolar levels and reoxidation by dissolved oxygen.

The lower limits of groundwater U(VI) can be achieved by in-situ biostimulation and the effects of dissolved oxygen on immobilized uranium are explored through a series of experiments at a pilot scale test facility.

Dynamics of Microbial Community Composition and Function during In Situ Bioremediation of a Uranium-Contaminated Aquifer

The results suggest that addition of electron donors stimulated the microbial community to create biogeochemical conditions favorable to U(VI) reduction and prevent the reduced U(IV) from reoxidation and that functional FeRB, SRB, and NRB populations within this system played key roles in this process.

GeoChip-based analysis of functional microbial communities during the reoxidation of a bioreduced uranium-contaminated aquifer.

It is suggested that the community in this system can be stimulated and that the ability to reduce U(VI) can be maintained by the addition of electron donors, and that this biostimulation approach may potentially offer an effective means for the bioremediation of U( VI)-contaminated sites.

Bioreduction Behavior of U(VI) Sorbed to Sediments

It is well known that microbially mediated reduction can result in the removal of U(VI)(aq) from solution by forming poorly soluble U(IV) oxides; however, the fate of U(VI) already associated with

Acetate Availability and its Influence on Sustainable Bioremediation of Uranium-Contaminated Groundwater

Field biostimulation experiments at the U.S. Department of Energy's Integrated Field Research Challenge (IFRC) site in Rifle, Colorado, have demonstrated that uranium concentrations in groundwater

Real — Time Speciation of Uranium during Active Bioremediation and U(IV) Reoxidation

The biological reduction of uranium from soluble U(VI) to insoluble U(IV) has shown potential to prevent uranium migration in groundwater. To gain insight into the extent of uranium reduction that

Elucidation of complex biogeochemical processes and their effects on speciation of U in the subsurface is critical for developing remediation strategies with an understanding of stability. We have

Uranium (VI) Reduction by Denitrifying Biomass

ABSTRACT Groundwater near the S3 ponds at the US Department of Energy's Y-12 site in Oak Ridge, Tennessee, is contaminated by high levels of nitrate (up to 160 mM) and U(VI) (∼0.3 mM). To minimize

Bioremediation and Bioreduction of Dissolved U(VI) by Microbial Mat Consortium Supported on Silica Gel Particles

The goal of this research was to simulate natural attenuation processes for uranium (U) by constructing a bioremediation system based on microbial mats. Ancient microbial consortia, such as microbial

Reoxidation of bioreduced uranium under reducing conditions.

It is proposed that kinetic limitations including restricted mass transfer allowed Fe-(III) and possibly Mn(IV) to persist as terminal electron acceptors (TEAs) for U reoxidation, thereby increasing the thermodynamic favorability of U( IV) oxidation.

Heterogeneous response to biostimulation for U(VI) reduction in replicated sediment microcosms

Investigation using the T-RFLP Analysis Program and chemical analyses detected the presence and activity of fermenting and sulfate-reducing bacteria after 2 weeks, indicating these organisms likely contributed to uranium reduction.

In situ bioreduction of technetium and uranium in a nitrate-contaminated aquifer.

The results suggest that NO3(-)-dependent microbial U(IV) oxidation may inhibit or reverse U(VI) reduction and decrease the stability of U( IV) in this environment.

Multiple influences of nitrate on uranium solubility during bioremediation of uranium-contaminated subsurface sediments.

These studies demonstrate that although the presence of nitrate is not likely to be an impediment to the bioremediation of uranium contamination with microbial U(VI) reduction, it is necessary to reduce nitrate before U( VI) can be reduced and suggest that anaerobic oxidation of U(IV) to U-VI with nitrate serving as the electron acceptor may provide a novel strategy for solubilizing and extracting microbial U-IV precipitates from the subsurface.
