Vanillin synthesis: Harnessing lignin resources from pulpwood trees through oxidative cleavage depolymerization

This study aims to assess the potential yield of vanillin from pulp-industry black liquor using alkaline hydrolysis with oxidative cleavage depolymerization techniques in different pulpwood tree species: Casuarina, Leucaena, Eucalyptus, and Eucalyptus ...

Comparative structural characterization of milled wood lignin and lignin carbohydrate complex fractions from larch tissues with representative oxidative transformation of sapwood LCC

Industrial Crops and Products
Lignin–carbohydrate complexes (LCCs) are covalent assemblies that contribute substantially to biomass recalcitrance, yet their tissue-dependent structural diversity in softwood and their fate during oxidative depolymerization remain insufficiently ...
