Research
interests
My current research centers on the physiology
and biochemistry of bacteria that respire oxyanions
of nitrogen, arsenic and selenium, and the microbial
sedimentation and lithification of modern marine
carbonate stromatolites In the first area, I am
investigating the reductases and electron transport
system of several dissimilatory metal reducing
bacteria. Respiration using alternative terminal
electron acceptors such as selenium and arsenic
oxyanions is a relatively new discovery. Ongoing
studies include the characterization of the arsenate
reductases of Sulfurospirillum barnesii
and Bacillus selenitireducens. In the second
area, living stromatolites from the Bahamas are
being studied using light and electron microscopy.
A collaborative effort with geologists, geochemists,
and other microbiologists from the Universities
of Miami, Connecticut, Maryland, and South Carolina,
we are attempting to elucidate the role of bacteria
in the lithification process of carbonate stromatolites.
In the third area, we have investigated phenolic-based
biocides for product protection.
