We investigated the interaction of dissolved actinides Th, U, Np, Pu, and Am, with a pure and a mixed culture of halophilic bacteria isolated from the Waste Isolation Pilot Plant repository under anaerobic conditions to evaluate their potential transport as biocolloids from the waste site. The sizes of the bacterial cells studied ranged from 0.54X0.48 μηι to 7.7 X0.67 μπι (lXw). Using sequential microfiltration, we determined the association of actinides with free-living (mobile) bacterial…

The potential of subterranean microbes in facilitating actinide migration at the Grimsel Test Site and Waste Isolation Pilot Plant

Microorganisms may affect the long-term stability and mobility of radionuclides disposed of in deep geological formations. Of particular concern is the association of radionuclides with subterranean

Actinide and metal toxicity to prospective bioremediation bacteria.

The results indicate that actinide toxicity is primarily chemical (not radiological), and that radiation resistance does not ensure radionuclide tolerance, and that Pu is less toxic than U and actinides are less Toxic than other types of metals, which suggests that act inide toxicity will not impede bioremediation using naturally occurring bacteria.

Radionuclide Geomicrobiology of the Deep Biosphere

This review summarizes research into interactions between microorganisms and radionuclides under conditions typical of a repository for high-level radioactive waste in deep hard rock environments at

Interaction of aerobic soil bacteria with plutonium(VI)

We studied the interaction of Pu(VI) with Pseudomonas stutzeri ATCC 17588 and Bacillus sphaericus ATCC 14577, representatives of the main aerobic groups of soil bacteria present in the upper soil

Interaction of actinides with aerobic soil bacteria

The production and testing of nuclear weapons, nuclear reactor accidents, and accidents during the transport of nuclear weapons have caused significant environmental contamination with radionuclides.

Distribution and activity of microorganisms in the deep repository for liquid radioactive waste at the Siberian Chemical Combine

It is indicated that the numbers and activity of microbial cells are low both inside and outside the zone of radioactive waste dispersion, in spite of the long period of waste discharge.

Microbial mobilization of plutonium and other actinides from contaminated soil.



Investigations of subterranean microorganisms. Their importance for performance assessment of radioactive waste disposal

The main actors in this report are the microorganisms (microbes is a synonymous designation). Let us therefore first define this concept. The following description can be read in the Swedish National

Microbial gas generation under expected Waste Isolation Pilot Plant repository conditions

Gas generation from the microbial degradation of the organic constituents of transuranic (TRU) waste under conditions expected in the Waste Isolation Pilot Plant (WIPP) was investigated. The
