- Many dissimilatory metal-reducing microorganisms can reduce the key radioactive contaminants, U and Tc from soluble high oxidation state forms to insoluble, low oxidation states forms (1). Little is known about the enzymatic mechanisms for these bioreductions. An understanding of these mechanisms is needed if these microorganisms are to be exploited in bioremediation technologies effectively and modeled accurately. G. sulfurreducens has been chosen for study because: It is an important component of subsurface biota (2); It's entire genome sequence is available (2); and A genetic system for this organism is available (3). The aims and objectives are: (1) To characterize the mechanisms of U(VI) and Tc(VII) reduction in G. sulfurreducens. (2) To confirm the identity of the genes encoding the relevant reductases in this organism. (3) To determine the range of other radionuclides (Np, Pu) and key metal pollutants (Cr, Hg, Co) reduced by G. sulfurreducens. (4) To identify the roles of the U(VI) and Tc(VII) reductases in the reduction of these other key pollutants.
