Previous studies have explored the potential of pomace valorization, with an emphasis on transformation polysaccharide biopolymers pomace-cellulose and hemicellulose to produce high-value bioproducts such as microcrystalline cellulose. Notably, opportunities for exploration biopolymer pomace-lignin its employment in biomedical applications tissue engineering not been comprehensively explored. T...
Lignin valorization is one of the biggest challenges for developing biomass-based chemical industry. Recent innovative works has enabled depolymerization lignin to monomers with yield close theoretical maximum. The main product a mixture phenols derived from cleavage β -O-4 linkages between phenylpropanoid units. However, obtained highly functionalized are not common in current industry and, th...
Redesigning lignin, the aromatic polymer fortifying plant cell walls, to be more amenable to chemical depolymerization can lower the energy required for industrial processing. We have engineered poplar trees to introduce ester linkages into the lignin polymer backbone by augmenting the monomer pool with monolignol ferulate conjugates. Herein, we describe the isolation of a transferase gene capa...
The glyoxalation of a methanol-fractionated alkali lignin was executed at 60 °C for 8 h with different amounts of glyoxal (40% in water) and 30% NaOH. The weights of the lignin and water were fixed at 10.0 and 15.0 g, respectively. The gel permeation chromatography (GPC) results indicated that depolymerization of lignin molecules occurred during the glyoxalation process. However, a higher polyd...
