Developments in terrestrial bacterial remediation of metals.
Recent advances in understanding the role and application of bacteria to the remediation of toxic metal and radionuclide contaminated terrestrial environments have come from several avenues. Novel species capable of mobilization and immobilization of metal ions have been discovered. Remediation of toxicity has been accelerated by nutrient amendment, the use of chelating agents and novel methods for phosphate amendment. Major advances in the use of natural and genetically engineered species for bioprotection and remediation of organic co-contaminants have been reported. Construction of wetland function continues to be developed for containment and decontamination of wastewaters.
