Microbes show promise for bioremediating plutonium

Article Abstract:

Researchers at Los Alamos National Laboratory report the ability of Microbacterium flavescens to take up plutonium with chelating agents, ingesting the plutonium like it would iron. The bioremediation of sites contaminated with plutonium may be possible through such research.

On the trail of bioremediating microbes

Article Abstract:

Chemical engineers Roseanne Ford and Peter Cummings will test the results of their research on bioremediating microbes by placing these microorganisms in ceramic balls and distributing these balls in the creosote-contaminated sediment of Virginia's Elizabeth River. Ford and Cummings' research on bioremediating bacteria has been extended to how their motility in a three dimensional medium affect their ability to degrade a pollutant and the speed at which bacteria moves through a pollutant gradient. The study will enable researchers to predict bacterial movement in the ceramic balls and improve their ability to degrade pollutants.
