Final Report: Role of microbial synergies in immobilization of metals

This Subsurface Microbial Ecology and Community Dynamics project tested the following hypothesis: synergistic groups of microorganisms immobilize heavy elements more efficiently than do individual species. We focused on groundwater at several DOE FRC and their microbial communities affecting the fate of U, Tc, and Cr. While we did not obtain evidence to support the original hypothesis, we developed a platform to accessing novel species from the target environments. We implemented this technology and discovered and isolated novel species capable of immobilization of uranium and species with exceptionally high resistances to the extant toxic factors. We have sequenced their genomes are are in the process of investigating the genomic contents behind these surprising resistances
