Oxygenase-Catalyzed Biodegradation of Emerging Water Contaminants: 1,4-Dioxane and N-Nitrosodimethylamine

Abstract

1,4-Dioxane (dioxane) and n-nitrosodimethylamine (NDMA) are emerging groundwater contaminants that are probable human carcinogens. Neither compound is significantly attenuated in the environment by volatilization or sorption processes, but a role for aerobic microbial processes in their removal has been observed. The objective of this SERDP project was to identify organisms, enzymes and biochemical pathways involved in the aerobic biodegradation of dioxane and NDMA, in order to develop a better understanding of the effects of bacterial degradation on the fate and persistence of dioxane and NDMA in the environment. This project focused specifically on oxygenase-catalyzed biodegradation of the targeted compounds.
