Unraveling the Science Behind Biomass Breakdown

Lignocellulosic biomass—plant matter such as cornstalks, straw, and woody plants—is a sustainable source for production of bio-based fuels and chemicals. However, the deconstruction of biomass is one of the most complex processes in bioenergy technologies. Although researchers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) had already uncovered information…
