Effects of organic carbon supply rates on uranium mobility in a previously bioreduced contaminated sediment.
Bioreduction-based strategies for remediating uranium (U)-contaminated sediments face the challenge of maintaining the reduced status of U for long times. Because groundwater influxes continuously bring in oxidizing terminal electron acceptors (O2, NO3(-)), it is necessary to continue supplying organic carbon (OC) to maintain the reducing environment after U bioreduction is achieved. We tested ...
متن کاملDynamics of microbial community composition and function during in situ bioremediation of a uranium-contaminated aquifer.
A pilot-scale system was established to examine the feasibility of in situ U(VI) immobilization at a highly contaminated aquifer (U.S. DOE Integrated Field Research Challenge site, Oak Ridge, TN). Ethanol was injected intermittently as an electron donor to stimulate microbial U(VI) reduction, and U(VI) concentrations fell to below the Environmental Protection Agency drinking water standard (0.0...
متن کاملIdentification of Bacteria Synthesizing Ribosomal RNA in Response to Uranium Addition During Biostimulation at the Rifle, CO Integrated Field Research Site
Understanding which organisms are capable of reducing uranium at historically contaminated sites provides crucial information needed to evaluate treatment options and outcomes. One approach is determination of the bacteria which directly respond to uranium addition. In this study, uranium amendments were made to groundwater samples from a site of ongoing biostimulation with acetate. The active ...

متن کاملAssessment of Bioaugmentation and Biostimulation Efficiencies for Petroleum Contaminated Sediments
The effectiveness of hydrocarbon bioremediation strategies approaches is depending on various issues such as type and volume of pollution, nutrient accessibility in the target ecosystem, time, biodiversity of microorganisms, pollutant bioavailability and many others. In the present research, laboratory studies were carried out on the bioremediation of coastal sediment samples ...
