The Great Lakes Bioenergy Research Center (GLBRC) is a cross-disciplinary research center led by the University of Wisconsin (UW)–Madison. With Michigan State University (MSU) and other collaborators, GLBRC is developing biobased fuels and products that are economically viable and environmentally sustainable.
GLBRC scientists envision a future in which dedicated energy crops grown on nonagricultural land provide the raw materials for major portions of society’s liquid transportation fuels and chemicals that are currently derived from petroleum. This future will create new economic opportunities for biorefineries, farmers, and rural communities and provide climate benefits without diverting land from food production. To fulfill this vision, the center is addressing key knowledge gaps that currently limit the industrial-scale production of specialty fuels and products from such purpose-grown energy crops.
Research Themes

Sustainable Cropping Systems. GLBRC is improving systems for growing dedicated energy crops on lands not currently used for agricultural purposes. Using nonagricultural land for nonfood crops, such as poplar, switchgrass, energy sorghum, and mixed perennial species, reserves arable U.S. farmland for food production, while simultaneously providing potential environmental benefits, such as climate change mitigation and increased biodiversity. The center’s goals are to maximize ecosystem performance and crop yield and quality under nutrient-limited or other stressful conditions found on nonagricultural lands. To achieve these goals, GLBRC research teams are:
- Engineering plants with lignin and polysaccharides that can readily be turned into specialty fuels and products.
- Identifying and developing plant and microbiome traits that improve energy crop productivity and tolerance to cold, drought, and nitrogen stress.
- Investigating micro- and landscape-scale controls on soil carbon sequestration, nitrous oxide emissions, and nitrogen fixation in energy cropping systems.

- Improving methods for feedstock-agnostic biomass deconstruction and separation by the renewable solvent gamma-valerolactone and broad-specificity glycosyl hydrolase enzymes.
- Identifying metabolic burdens and lignocellulosic hydrolysate stresses and how they pose barriers to efficient production of isobutanol (IBA) by industrially accepted microbes.
- Generating the knowledge needed to design new industry-ready platform microbes capable of producing targeted products from conversion residues derived from specialty fuel production.
Field-to-Product Integration. The path from farm field to products consists of several interdependent phases, including crop production, biomass deconstruction, and conversion into targeted products that are of value to industry. GLBRC’s multidisciplinary research teams are building, modeling, and evaluating strategies for the next-generation lignocellulosic bioindustry to improve these individual steps while integrating them into an optimized field-to-product pipeline. To achieve these goals, GLBRC research teams are:
- Creating novel and robust plant, landscape, and biorefinery models to predict the sustainability, lifecycle, and economic outcomes of alternative field-to-product pipelines.
- Laying the groundwork to understand how the performance of conversion microbes is affected by seasonal or environmental changes in energy crops.
- Developing capacities for improved microbial conversion of lignin into products.
- Enabling the efficient production of terpenes by plants and microbes.

Industry Partnerships
GLBRC works closely with companies and licensing agents to anticipate industrial needs, move new technologies into the marketplace, and advance the overall economics of biorefining. Industry collaborations help the center focus its research on critical industry bottlenecks and more quickly develop new technologies for commercial use, while industry representatives on GLBRC’s scientific advisory board provide valuable perspective and guidance on research directions. GLBRC intellectual property (IP) is protected by and commercialized through the Wisconsin Alumni Research Foundation, a nonprofit entity that manages and licenses UW–Madison IP, and MSU Technologies, MSU’s technology transfer and commercialization office. These two organizations provide companies with opportunities to acquire rights in GLBRC inventions and copyrights to drive commercialization and create new economic opportunities for biorefiners, farmers, and rural communities.
