Research Description

Research in the Watkins lab is focused on understanding the mechanism of bacterial desulfurization of fossil fuels. Thiophenic compounds, usually resistant to traditional desulfurization methods, are selectively desulfurized by bacterial systems containing the dsz genes. However, the expression levels of the gene, and the thermal stability, enzymatic rate and substrate selectivity of the enzymes involved limit the effectiveness of the system. Efforts to increase the effectiveness of this desulfurization method depend on a better understanding of the enzymes involved in the desulfurization process. Other areas of research include testing the ability of enzymes to modify monomers commonly used in polymer synthesis, and isolating and characterizing novel biodegradation enzymes from soil bacteria.
