Nitrification; agriculturally and environmentally relevant microbial biochemistry and physiology, bioremediation.

Description of Research

Work in my laboratory focuses on two aspects of microbial physiology, biochemistry and molecular biology. First, we are investigating the process of nitrification which involves the oxidation of ammonia to nitrate. Genomes for key organisms guide our studies of the pathways, regulation, and enzymes associated with both ammonia oxidation and nitrite oxidation.  Second, we are interested in gaseous alkane oxidation by bacteria with a particular focus on butane. Butane is harvested from the environment by a monooxygenase. Three bacteria under investigation have distinct monooxygenases. One monooxygenase contains a di-iron center.  Recent work has identified a new member of this superfamily of proteins that contain di-iron centers.
