Removing recalcitrance as an economic barrier for sustainable cellulosic biofuels
Biomass recalcitrance is the primary barrier to efficiently and economically accessing fermentable sugars for advanced biofuels that will directly displace petroleum. Convinced that biotechnological approaches hold the most promise for achieving these breakthroughs, the BioEnergy Science Center (BESC) is developing plants that are easier to deconstruct and microbes that more effectively convert lignocellulose into simple sugars.
BESC research involves working with two potential bioenergy crops (switchgrass and Populus) to develop varieties that are easier to break down into fermentable sugars and to understand how plant cell walls are formed and can be modified to improve sugar release.
BESC research in biomass deconstruction and conversion targets consolidated bioprocessing (a single-step process) by studying model organisms and thermophilic anaerobes to understand novel strategies and enzyme complexes for biomass deconstruction.
BESC researchers in characterization, modeling, and data management areas are engaged in (1) applying advanced technologies to analyze chemical and structural changes within biomass, and (2) storing, tracking, analyzing, and integrating data and understanding across the center.
