Biomass Resource Supply, Development & Characterization: Biomass Recalcitrance to Deconstruction

Tuesday, April 30, 2013: 8:00 AM-11:30 AM
Pavilion, Plaza Level
Convener:
Shawn Mansfield - University of British Columbia, Vancouver,
Co-Convener:
Jane Lindedam - University of Copenhagen, 1958 Frederiksberg C,
• Biophysical origins of biomass recalcitrance. • Fundamental studies of plant cell wall biogenesis and perturbation of cell wall synthesis to alter recalcitrance. • Improvements in understanding cell wall structure and composition. • The roles of hemicelluloses, pectins and lignins in recalcitrance.
