Fuels made from agricultural or forestry wastes known as lignocellulosic biomass have long been a champion in the quest to reduce use of fossil fuels. But plant cell walls have some innate defenses that make the process to break them down more difficult and costly than it could be.
In a leap forward that could be a game changer for understanding how plant biomass can be more efficiently broken down, a research team at the University of California, Riverside have joined forces with teams at Oak Ridge National Laboratory and the University of Central Florida to create a chemical roadmap to breach these defenses.
In order to access the energy-rich sugars found in the plant cell walls, researchers have renewed focus on solvating lignin, a complex polymer also found in plant cell walls that acts as a natural shield, blocking both chemical and biological attack. Lignin is particularly effective in preventing commercial enzymes from digesting cellulose, which makes up the bulk of sugars found in biomass.
