Separation and catalytic depolymerization of empty palm fruit bunch lignin

Lignin is a heterogeneous and complex polymer and a potential renewable source of aromatic compounds as precursors to many industrially useful products. Microbial biotransformations for lignin valorization are reported but require not only its separation from biomass matrix but also breakdown into its monomeric components. Abundantly available empty palm fruit bunch was used as the lignin-rich biomass to process it to obtain a mixture of...
