Lignin, a polymer that makes trees rigid and resistant to degradation, has proven problematic. Now those NC State researchers know why: They’ve identified the specific molecular property of lignin — its methoxy content — that determines just how hard, or easy, it would be to use microbial fermentation to turn trees and other plants into industrial chemicals.
The findings put us a step closer to making industrial chemicals from trees as an economically and environmentally sustainable alternative to chemicals derived from petroleum, said the corresponding author of a paper in the journal Science Advances detailing the discovery.
