Annual Progress Report on Research Related to Our Research Project Stabilization of Plutonium in Subsurface Environments via Microbial Reduction and Biofilm Formation Funded by the Environmental Remediation Sciences Division (ERSD)

摘要

The overarching goal of this research project is to investigate and optimize the mechanisms for in situ immobilization of Pu species by naturally-occurring bacteria. Specific research objectives are: (a) investigate the mechanism of bacterial accumulation and immobilization of plutonium species by biofilm formation under aerobic conditions and (b) to demonstrate the direct and indirect stabilization of Pu via dissimilatory reduction by Geobacter metallireducens.
