Abstract excerpt
Immobilization of cadmium (10 mg Cd per kilogram soil) in soil by bioaugmentation of a UV-mutated microorganism, Bacillus subtilis 38 accompanied with amendment of a bio-fertilizer, NovoGro was investigated using extractable cadmium (E-Cd) by DTPA. B. subtilis 38, the mutant with the strongest resistance against Cd, could bioaccumulate Cd four times greater than the original wild type. Single bioaugmentation of...
