ABSTRACT:
The concentration of at least one metal species in an aqueous system is at least reduced in an aqueous system that contains at least one kind of chelating agent, by adding to such system a species or plurality of species of bacteria that have a low toxicity for the metal species, and establishing and maintaining a biomass in the system for a sufficent time period to reduce the metal concentration.
