Microbes in Basalt Thrive on a Mixed diet of Toxic Wastes

Paul Preuss, Lawrence Berkley National Laboratory

Berkley lab news site on the bacterium Arthrobacter oxydans. This bacterium was found Seventy-five meters beneath the surface of a site in Idaho where radioactive waste has been stored for more than 40 years, the microbe living in the pores and crevices of dry basaltic rock was able to reduce a toxic form of chromium to a much less toxic form in the presence of volatile organic wastes. In addition to the article this site provides links to the lab's home page, index, and other news articles.
