Achieving efficient pretreatment of corn straw at elevated temperatures via constraining cellulose degradation

Preparation of a Lignin-Based Adsorbent from Xylitol Residue for the Capture of Metal Ion in Aqueous Solutions

“…After dilution, hydrolysis, and filtration, the remaining solids were considered to be acid-insoluble lignin. The detailed operating procedures were as follows: 0.3 g of xylitol residue and 3 mL of a sulfuric acid solution [72% (w/w)] were added to a 10 mL glass tube, which was placed in a shaker for acid hydrolysis at 30 °C for 1 h. After completion, the solution was diluted with 84 mL of ultrapure water in a 100 mL conical flask. After sealing with a sealing film, the flask was placed in a high-pressure sterilization pot for 45 min at 121 °C.…”

Functional deep eutectic solvent for lignocellulose valorization via lignin stabilization and cellulose functionalization

“…Although these strategies promote enzymatic saccharification of glucan, their industrial applications face many challenges, such as cost and energy consumption. 7,8 DES, a typical eutectic mixture consisting of a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD), has been identified as a promising media for biomass pretreatment due to its high lignin solubility, non-flammability, good bio-compatibility, and thermostability. 5,9,10 In particular, the ChCl-based DES exhibits an excellent ability to selectively dissolve lignin and hemicellulose from lignocellulosic biomass.…”
