AMHERST, Mass. - A team of microbiologists at the University of Massachusetts has uncovered the unusual survival strategies used by a common bacterium. The finding could have implications in cleaning up contaminants ranging from petroleum to uranium. The study, by Derek Lovley, head of the microbiology department, and Susan Childers, a postdoctoral researcher, will be detailed in the April 18 issue of the journal Nature. The research was funded by the National Science Foundation and the U.S. Department of Energy.
