1999

In August, 1998, the DOE, through its Office of Biological and Environmental Research, awarded 21 research grants in the NABIR program. Twenty of the awards covered scientific research in four of NABIR's seven scientific program elements: Assessment; Biotransformation and Biodegradation; Community Dynamics and Microbial Ecology; and System Engineering, Integration, Prediction, and Optimization; An award was also granted for research in the Bioremediation and Its Societal Implications and Concerns (BASIC) program element.
