ABSTRACT:
Disclosed is a biological process for recovering plutonium from soils using an iron-reducing bacterium, Bacillus circulans NRRL B-21037. A process for obtaining such bacteria is disclosed. The invention process gives upwards of about 88% yield of plutonium from soils. Further, pertinent gene(s) encoding enzymes obtainable from iron-reducing microbes can be used by placing such gene(s) on a suitable vector and transforming a competent host. The transformed host then can be used in the same manner as the native bacterium.
