Abstrakt: The article examines the biostimulation of the endogenous microbial communities to improve nitrate reduction and subsequent hexavalent uranium [U(VI)] reduction under conditions of elevated heavy metals at the site of the Field Research Center (FRC) at Oak Ridge National Laboratory in Tennessee. It cites the use of column experiments to test the possibility of using biostimulation via the addition of ethanol as a carbon source for the improvement of nitrate reduction in the presence of elevated aqueous nickel. It shows that the necessary information to adopt to the implemented nickel stress occupies in the endogenous microbial population present at the Oak Ridge FRC site.
