Bioremediation of metals and radionuclides has had many field tests, demonstrations, and full-scale implementations in recent years. Field research in this area has occurred for many different metals and radionuclides using a wide array of strategies. These strategies can be generally characterized in six major categories: biotransformation, bioaccumulation/bisorption, biodegradation of chelators, volatilization, treatment trains, and natural attenuation. For all field applications there are a… 

Developments in Bioremediation of Soils and Sediments Polluted with Metals and Radionuclides. 3. Influence of Chemical Speciation and Bioavailability on Contaminants Immobilization/Mobilization Bio-processes

The biotransformation of metals is an exciting, developing strategy to treat metal contamination, especially in environments that are not accessible to other remediation technologies. However, our

Critical research needs in this area include better modeling and integration of remediation strategies with natural attenuation.

Rehabilitation of Radioactively Contaminated Soil: Use of Bioremediation/Phytoremediation Techniques

The release of radionuclides in the environment is of major concern. Radionuclides arise mainly from nuclear power production, nuclear accidents, nuclear weapons testing, uranium mining and

92 Biostimulation

Using a systems biology approach, not only what microbes are present, but their in situ activities to trace nutrients, electron donors, electron acceptors, contaminants, and environmental stressors will be enabling to develop conceptual and numerical models for the best biostimulation strategy and better long-term stewardship of the environment.

Bioaugmentation for Groundwater Remediation: an Overview

It is likely that use of bioaugmentation will increase, and be expanded to address other contaminants and use new techniques, such as the development of genetically-engineered microbes and additions of mobile genetic elements such as plasmids.

BioRadBase: A database for bioremediation of radioactive waste

Bioremediation of radioactive waste (BioRaDBase), the first database dedicated to micro-organisms which have been explored or engineered to remediate radioactive waste from the environment, serves as a comprehensive knowledgebase to search bacteria and fungi which have the ability to transform radioactive waste.

Bioaugmentation for Groundwater Remediation

Bioaugmentation for Groundwater Remediation is used for Aerobic Degradation of CIS-1,2-Dichlorothene and for the In Situ Aerobic Cometabolism of Chlorinated Solvents.



Bioremediation of Metals and Radionuclides

An overview of metal-microbe interactions and how they could be harnessed to clean up metal-contaminated water, soil, and land are described and supported by genomics-enabled studies ongoing in many laboratories worldwide are described.

Bioremediation of metals and radionuclides: What it is and How itWorks

This primer is intended for people interested in DOE environmental problems and in their potential solutions. It will specifically look at some of the more hazardous metal and radionuclide

Bioremediation of metal‐contaminated surface and groundwaters

Several proprietary processes, which employ nonliving microorganisms that are immobilized in polymer matrixes, are entering the water treatment market and effectively remove low concentrations of heavy metal cations in the presence of high concentrations of alkaline earth metals and organic contaminants.

Bioremediation process for sediments contaminated by heavy metals: feasibility study on a pilot scale.

A cost-effectiveness assessment of the remediation process indicates conditioning dredged sludge by plants and the solid-bed leaching of heavy metals using microbially produced sulfuric acid to be a suitable treatment for restoring polluted sediments for beneficial use.

Bioremediation of selenium‐contaminated sediments and water

A biotechnology prototype was developed which could be applicable for cleanup of polluted sediments and water throughout the western United States and revealed that DMSe is nontoxic.

In situ soil treatments to reduce the phyto- and bioavailability of lead, zinc, and cadmium.

The 1% P-H3PO4 treatment was the most effective at reducing plant Pb, Zn, and Cd in situ and caused the greatest reduction in in vitro extractable Pb from field samples.

Assessment of metal availability in smelter soil using earthworms and chemical extractions.

Lime-stabilized municipal biosolids was the only remediation amendment to successfully immobilize lethal levels of Zn in the smelter soil, and Chelating ion-exchange membrane uptake among the soils was highly variable compared with the Ca(NO3)2-extraction and not well related to earthworm toxicity.

Chemical immobilization of lead, zinc, and cadmium in smelter-contaminated soils using biosolids and rock phosphate.

Alkaline organic treatments can reduce human exposure to Cd and Pb by reducing Zn phytotoxicity and revegetation of contaminated sites and alkaline organic Treatments (LSB, NV) decreases Cd transmission through the food chain pathway, whereas rock phosphate decreases risk from exposure to Pb via the soil ingestion pathway.

Selected bioavailability assays to test the efficacy of amendment-induced immobilization of lead in soils

Lead immobilization in 10 soils contaminated with Pb from different origin was examined using lime (CaCO3), a mix of cyclonic ash and steelshots (CA+ST), and a North Carolina phosphate rock. The
