The field of Metabolic Engineering has recently undergone a transformation that has led to a rapid expansion of the chemical palate of cells. The incorporation of tools from synthetic biology and directed evolution has enabled a newfound control of cells. Now, it is conceivable to produce nearly any organic molecule of interest using a cellular host—from biofuels to biopolymers to pharmaceuticals. However, these feats require the ability to “hijack” native cellular machinery and metabolism and navigate the complexity inherent in cellular regulation. Of the many possible host organisms, yeasts are a growing host for industrial products and have many outstanding, biotechnologically-desirable native traits. This talk will describe recent advances in our laboratory for engineering both conventional (e.g. Saccharomyces cerevisiae) and non-conventional (e.g. Yarrowia lipolytica) yeasts for the production of important products such as organic acids and oleochemicals. This talk will emphasize the development of new tools for synthetic biology (especially synthetic promoters and terminators) and directed evolution along the way to pathway engineering. Collectively, these case studies demonstrate the power and utility of using yeasts as a production host for chemicals.
Dr. Hal Alper is an Associate Professor and Fellow of the Paul D. & Betty Robertson Meek Centennial Professorship in Chemical Engineering at The University of Texas at Austin. He earned his Ph.D. in Chemical Engineering from the Massachusetts Institute of Technology in 2006 and was a postdoctoral research associate at the Whitehead Institute for Biomedical Research from 2006-2008, and at Shire Human Genetic Therapies from 2007-2008. Dr. Alper also serves on the Graduate Studies Committee for the Cell and Molecular Biology Department and the Biochemistry Department. He is currently the Principal Investigator of the Laboratory for Cellular and Metabolic Engineering at The University of Texas at Austin where his lab focuses on metabolic and cellular engineering in the context of biofuel, biochemical, and biopharmaceutical production in an array of model host organisms. His research focuses on applying and extending the approaches of related fields such as synthetic biology, systems biology, and protein engineering.
