3 Comparative study of lignin characteristic from wheat straw obtained 4 by soda-AQ or kraft pretreatment and effect on the following enzymatic 5 hydrolysis process

Efficient separation of lignin from mild alkaline hydrolysate of bagasse by selective adsorbent resin

Amongst industrial lignins, such as alkaline and kraft lignins, lignin from hemicellulose pre-treatment liquor is gaining considerable interest because of its various properties. To explore application potential, a lignin sample that was selectively adsorbed by XAD-16N resin from mild alkaline extracts of sugarcane bag...

Sugar Beet Pectin-lignin Films: Effect of Lignosulfonates and Colloidal Lignin Particles on Packaging Performance and Sea Bass Preservation

Mixed-acid and organic-amine pretreatments for effective sugar production from corncob

Effective pretreatment is essential for producing fermentable sugars from lignocellulosic biomass. In this study, mixed-acid and organic-amine pretreatments were conducted for corncob deconstruction, component fractionation, lignin removal, and enzymatic saccharification. The sulfuric acid/maleic acid system (1:1, w/w)...

Fractionation of rice straw lignin with choline chloride acidic deep eutectic solvents: Structural characterization and multifunctional functional properties.

Lignin is largely wasted agro-industrial aromatic biomass. Green deep eutectic solvents (DES) fractionation optimizes its UV-blocking, antioxidant and antibacterial performance, outperforming traditional alkali extraction. This study compares NaOH and four choline chloride acidic DES to reveal their regulation effects...

Understanding Process‐Induced Structural Changes in Rice Straw Technical Lignins to Determine Their Valorization Potential

A detailed understanding of the composition and chemical structures of technical lignins is essential for designing effective valorization strategies. This study examined four lignins from rice straw: soda lignin (SL), ethanol organosolv lignin (EOL), and two dioxane organosolv lignins (DOL‐a and DOL‐b), to compare...

Lewis acid-diol deep eutectic solvents for structurally retained lignin fractionation and corn stover saccharification.

Lewis acid-diol-based deep eutectic solvents (DESs) were constructed for technical lignin dissolution and corn stover (CS) fractionation. The DESs showed high dissolution capacities toward kraft lignin, enzymatic hydrolysis lignin and alkaline lignin with maximum solubilities of 58.4 wt%, 78.8 wt% and 45.5 wt%, respect...
