Researching methods to help control radioactive contamination from uranium, scientists have discovered that some bacteria that are found in the soil and subsurface can release a phosphate that converts uranium contamination into an insoluble and immobile form.
Based on laboratory studies, Georgia Institute of Technology researchers have reported promising results using bacteria isolated from subsurface soils collected at a Department of Energy (DOE) field research center site in Oak Ridge, Tenn. Researchers conducted preliminary screenings of many bacterial isolates and found several candidate strains that released inorganic phosphate after hydrolyzing an ...
