AI Article Synopsis
- A new deep eutectic solvent (DES) using NaS was developed to effectively break down the tough structure of moso bamboo while keeping important components like glucan and hemicellulose intact.
- * The addition of NaS led to a 74.67% removal of lignin, achieving an impressive 100% enzymatic saccharification yield at 140°C, while also allowing for a high lignin recovery rate of 81.47%.
- * This DES outperforms traditional alkaline DES by providing better lignin removal, higher carbohydrate preservation, and increased enzymatic digestibility, making NaS a valuable tool for enhancing biomass processing efficiency.
Article Abstract
Herein, a NaS promoted deep eutectic solvent (DES) was established to reduce the natural recalcitrance of moso bamboo (MB) and improve the subsequent enzymatic saccharification. It was found that the addition of NaS (Choline chloride/Ethylene glycol/NaS) dramatically promoted the deconstructions of lignin with highest removal of 74.67 %, but at the same time preserved glucan and hemicellulose to the maximum extent. With the fractionation, the enzymatic saccharification yield of pretreated MB can reach 100 % under the pretreatment condition of 140 °C, and lignin could be readily recovered with a high yield of 81.47 %. The proposed DES is superior to normal alkaline DES in terms of the higher lignin removal and recovery yield, carbohydrate preservation and enzymatic digestibility, which indicated NaS as a novel and powerful reinforcer enhancing the DES fractionation efficiency.
