The Oak Ridge Reservation is contaminated with acidic, high-nitrate-and high-metal substances. Microbes in this environment can use molybdenum to remove nitrate, but the low concentration of molybdenum at Oak Ridge limits how much nitrate the microbes can remove. Two studies examine why molybdenum is limited and the mechanisms some microbes use to survive these conditions.
A Florida State University researcher will lead a study into how bacteria can be used to remove carcinogens from groundwater thanks to a $1.4 million grant from the National Institute of Environmental Health Sciences.
