Developing bioremediation strategies for actinides

Microbiological based remediation technologies provide new approaches to remove toxic metals from the environment. For example, reducing the bioavailability of soluble actinide species, through bacterial mediated mineralisation has the potential to significantly reduce water pollution. Our group is working to understand these mineralisation processes by examining the interactions between different actinide species and microbial macromolecules and by identifying the cellular processes by which actinides are retained intra and extra cellularly. Experimental and computational work is being carried out to find and mimic those bacterial-mineral interactions which may be used to produce a strategy for removal of radioactive species from the environment.
