Biocatalysis encompasses a wide platform of chemistries that afford opportunities for innovative new products and processes. Hallmarks of biocatalysts are their ability to operate under mild conditions, with impressive selectivity, on a diverse range of natural and non-natural substrates. Rapid advances in biotechnology continues to decrease the time and resources required to engineer organisms to produce desired products in high titers as well as to engineer enzymes with increased thermal stability, efficiency and specificity. Our group works with collaborators to apply existing, or develop new, biocatalytic methods that solve short or long term chemistry challenges. With sufficient focus on structure-property relationships of natural and biobased materials, they can become next-generation replacements for a wide array of currently used non-sustainable petroleum-derived materials. While most attention is focused on biomass for transportation fuels, less is paid to biomass as a source for organic chemicals including polymeric materials. This is true even though biomass-derived carbon can realistically replace most or possibly all nonfuel chemical uses, which comprise ~13% of the crude oil consumed by the U.S. today. Our program explores a wide range of opportunities for use in biobased replacements such as biobased and degradable polymers, biosurfactants, biofibers for commposite reinforcement and advanced materials opportunities such as in photovoltaic materials for energy harvesting; composite materials used, for example, in wind-blade turbines for wind energy harvesting, epoxies for circuit boards and much more.
