Global climate stabilization requires radical reductions in anthropogenic carbon dioxide emissions as well as removal of carbon dioxide from the atmosphere on a large scale. Liquid fuels produced from cellulosic biomass have a unique ability to contribute to meeting both requirements, in particular for heavy-duty transportation (aviation, ocean shipping and long-haul trucking) for which energy storage with batteries or hydrogen is particularly challenging. Existing cellulosic biofuel production technology based on yeast is expensive, motivating the exploration of lower-cost alternatives.

After considering the importance of biofuels in climate stabilization, this seminar will describe an alternative approach to the conventional yeast-based processing paradigm: starting with organisms that have evolved in nature for their ability to rapidly consume cellulose, and then engineering them for improved biofuel production. This work includes the development of genetic tools, the use of those tools to alter metabolism to increase biofuel production, and work to better understand the underlying principles that govern the ability of microorganisms to produce biofuels at the high concentrations needed for commercial applications.
