Summary: In this study, a three-constituent deep eutectic solvent (3c-DES) pretreatment was used to examine its efficiency on bamboo residues. The results showed that the 3c-DES pretreatment effectively removed xylan and improved the hydrolysis yield. The introduction of ethylene glycol (EG) and the addition of Tween 80 further enhanced the effectiveness of the pretreatment. This research has significant implications for the development of bamboo biorefinery.

Summary: In this study, a metal salt-based deep eutectic solvent (DES) composed of FeCl3 and glycerol was used for the pretreatment of moso bamboo. The results showed that FeCl3-based DES was optimal for the removal of hemicelluloses and lignin. Increasing the pretreatment temperature and time resulted in a higher removal rate. This study highlights the potential of metal salt-based DES for the value-added conversion of moso bamboo under mild conditions.

Summary: Acidic deep eutectic solvent (DES) pretreatment is a promising method for lignocellulose fractionation. This study developed a DES consisting of choline chloride and oxalic acid (ChCl/OA) to pretreat moso bamboo and investigated the effects of pretreated residue on enzymatic hydrolysis. The results showed that ChCl/OA pretreatment effectively removed hemicelluloses and lignin, leading to improved glucose yield. However, excessive removal of lignin negatively affected enzymatic hydrolysis. The study also revealed that surface lignin, hydrophobic interaction, and accessibility influenced enzymatic hydrolysis.

Summary: This study revealed that removing surface lignin significantly decreased the yield for enzymatic hydrolysis of DAP-BR and that the affinity constants of all tested lignins exhibited good correlations with the effects on enzymatic digestibility. Additionally, MWL samples showed a stronger affinity for cellulase enzymes compared to SL samples due to their higher molecular weight and hydrophobicity.

Summary: The interference of silicon in bamboo pulp black liquor has been a problem for pulp mills, hindering the development of non-wood pulp mills. Silica is separated from black liquor through acid precipitation, which is disadvantageous to the alkali recovery system due to lignin sedimentation. By increasing the carboxylate amount through lignin oxidation, the solubility of lignin also increases. The silicon removal and lignin separation can be quantified by combining acidification and light oxidation.

Summary: This study proposed a promising biorefinery method using P-TsOH pretreatment to produce high-purity cellulose from moso bamboo. The cellulose pulp obtained had high α-cellulose content (82.36%) after a short pretreatment time at low temperature. The properties of the cellulose pulp met the standard of dissolving pulp after bleaching and cold caustic extraction processes, and the cooking method significantly reduced energy and chemical consumption.
