Fermenting revolution: Biocatalysis at the U

Bob Elde, dean of the U's College of Biological Sciences, believes that the time for biocatalysis is now and the place is Minnesota. "Biocatalysis is in its infancy," he says. "Right now, there isn't a hub for biocatalysis in the U.S. [and] we have a limited opportunity to seize the day and make this our niche in biotechnology. If we don't, another state will beat us to it." Elde has been working with University, industry, and government leaders to bring resources, such as raw materials and academic expertise, together to make Minnesota a center for this new industry. Biocatalysis means using enzymes (naturally occurring or engineered) to catalyze chemical reactions. It's not a new idea. Fermentation, used since ancient times to make bread and wine, is a type of biocatalysis that employs yeast as a catalyst. But advances in scientists' ability to engineer biocatalysts for specific purposes, combined with dwindling oil reserves and the effect of petrochemicals on the environment, have given the approach a new life. While chemical manufacturing often relies on expensive, toxic catalysts and requires huge amounts of energy, biocatalysis relies on natural enzymes and uses far less energy to achieve similar results. Claudia Schmidt-Dannert, an assistant professor of biochemistry, molecular biology, and biochemistry, is among many University of Minnesota faculty engaged in biocatalysis research and in other fields that support the renewable resources and energy initiative. While Schmidt-Dannert "shuffles" the genes of bacteria to generate new forms of enzymes and biosynthetic pathways for new drug development, Lanny Schmidt, Regents Professor of Chemical Engineering, is focused on fuel cells. He recently led a team of U researchers in creating the first reactor capable of converting ethanol into hydrogen to efficiently power hydrogen fuel cells.

"Biocatalysis works with nature rather than
against it," Elde says. "This is our chance to undo some of the
damage petrochemicals have done to the environment and make the
world a better place for future generations... "
