I am interested in both fundamental questions in microbial ecology as well as the application of unique microbial species for bioremediation. There are three major areas of interest in my lab:1) the ecophysiology, biochemistry, and molecular biology of dissimilatory metal reducing bacteria, 2) the ecophysiology of phototrophic prokaryotes and 3) bioremediation. In the first area, I am investigating the reductases and electron transport system of several dissimilatory metalloid reducing bacteria. Respiration using alternative terminal electron acceptors such as arsenic and selenium oxyanions is a relatively new discovery. Ongoing studies include the characterization of the arsenic metabolism in the chemolithoautotroph Alkalilimnicol ehrlichii, nitrate enhanced chromate reduction by Desulfovibrio desulfuricans, Sulfurospirillum barnesii, and Geobacter metallireducens, and the biotransformation of inorganic arsenic and organoarsenicals. The approach is interdisciplinary and is done in collaboration with Dr. Partha Basu in the Department of Chemistry and Biochemistry. The lab is currently funded by grants from DOE, NASA, NSF, and NIEHS. Contact me: stolz@duq.edu
