Elizabeth A. Edwards PhD, P. Eng., Professor Department of Chemical Engineering and Applied Chemistry University of Toronto

Dr. Elizabeth Edwards holds Bachelor's and Master's degrees in Chemical Engineering from McGill University, Montreal, and a PhD degree (1993) in Civil and Environmental Engineering from Stanford University.  She is internationally known for her work on anaerobic bioremediation, the application of molecular biology and metagenomics to uncover novel microbial processes, and the transition of laboratory research into commercial practice to develop bioremediation and bioaugmentation strategies for chlorinated solvent remediation.

Presentation Description
Compound Specific Stable Isotope Fractionation to Distinguish Metabolic Pathways in Microbial Systems
Compound specific stable isotope fractionation in combination with careful analyses of contaminant transformation reaction substrates and products in microbial systems can provide a very useful way to explore novel metabolic pathways, and hone in on important reaction mechanisms. Several examples of the application of stable isotope fractionation to investigate and compare oxidative and reductive biodegradation pathways will be provided.
