Overview

Randomized trial demonstrates effective biomass utilization by enhancing lignin extraction and carbohydrate separation, indicating a novel refining method.

Key Points

  • This research aims to improve biological refining of biomass through a lignin-first approach, enhancing lignin extraction and depolymerization.
  • Implemented aerobic oxidation for biomass pretreatment.
  • Combined hydrolytic fractionation with in situ lignin oxidative modification.
  • Yielded oxidized lignin and carbohydrate residue under optimized conditions.
  • Yield of oxidized lignin reached 17.1%, and carbohydrate residue reached 59.9%.
  • Phenolic monomer yield from oxidized lignin was 245.0 mg g−1, surpassing Kraft lignin (26.3 mg g−1) and sodium lignosulfonate (44.0 mg g−1).
  • Enhanced depolymerization attributed to abundant aryl α-ketone functional groups from linkages, reducing activation energy.
