Enzymatic Depolymerization of Lignin
Unlike existing chemical methods, this new bio-based route eliminates expensive catalysts and results in a well-defined set of aromatic monomers that are natural bioproducts, have not undergone chemical transformation and are more amenable to downstream processing/upgrading.
