Catalytic aerobic oxidation under aqueous alkaline conditions promotes C–C cleavage in pine‐ and poplar‐derived lignin oligomers, accessing high yields of aromatic monomers. The monomeric phenols obtained from this process then undergo effective biological conversion into cis,cis‐muconic acid and 2‐pyrone‐4,6‐dicarboxylic acid using engineered strains ...

Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Studying the effects of laccase treatment in a softwood dissolving pulp: cellulose reactivity and crystallinity [PDF]
An enzymatic biobleaching sequence (LVAQPO) using a laccase from Trametes villosa in combination with violuric acid (VA) and then followed by a pressurized hydrogen peroxide treatment (PO) was developed and found to give high bleaching properties and ...

Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Catalyst system investigation in biomimetic delignification of oil palm empty fruit bunches
Biomimetic delignification of oil palm empty fruit bunches with the bio-inspired chemical catalyst system was investigated by mimicking the ligninolytic enzyme's redox mediator formation, i.e., Mn3+ and H2O2.

Extended Oxygen Delignification with the Oxy TracTM Process
Many mills have adopted oxygen delignification systems in order to decrease chemical consumption in a bleaching plant since 1970's.Generally, the maximum delignification obtained by oxygen delignification system keeping pulp strength has been considered about 50% for softwood pulp because possible delignification by oxygen is limited to certain groups ...
