Summary: In this study, Coprinus comatus was found to effectively degrade lignocellulose in corn stalk. Various analyses, including scanning electron microscopy, specific surface area measurement, X-ray diffraction, Fourier infrared spectroscopy, and gas chromatography-mass spectrometry, were conducted to characterize the changes in corn stalk. The results showed that Coprinus comatus achieved a lignin degradation rate of up to 38.66%. The fungus eroded the structure of the corn stalk, forming pores that accelerated lignin degradation. Treated corn stalk exhibited increased specific surface area, reduced crystallinity, and the presence of small molecular substances. These findings demonstrate the effectiveness of Coprinus comatus for corn stalk degradation and suggest further investigation is needed to explore its potential in this field.

Summary: This study introduces a novel combined pretreatment approach involving steam explosion and GVL/water delignification to improve the enzymatic saccharification efficiency of corn stalk. The method effectively removes lignin and enhances glucan content in the solid material, leading to significantly increased glucose concentration during high-solid loading enzymatic hydrolysis with relatively low cellulase addition. The combined pretreatment shows promise for green lignocellulosic biorefinery by fractionating corn stalk and producing a glucan-enriched solid with enhanced enzymatic digestibility.

Summary: The esterification reactions between citric acid and lignin inhibit the formation of reactive intermediates in acid-catalyzed pretreatments. Adding citric acid to the pretreatment leads to higher cellulose recovery and lignin removal. Water content also plays an important role in the pretreatment and delignification process. The presence of citric acid improves enzymatic saccharification of cellulose by inhibiting repolymerization of degraded lignin fragments.

Summary: This study investigated the role of formaldehyde in inhibiting lignin condensation during corn stalk pretreatment with [C4C1im]Cl/HCl system. Formaldehyde addition affected the structural features of lignin and the composition of degraded products significantly.
Stabilization by formaldehyde was unfavorable for the cleavage of ?-O-4 bonds, leading to the extraction of lignin with low S/G ratio and high molecular weight in the [C4C1im]Cl/HCl/FA system.

Summary: A water-soluble cationic kraft lignin (JLQKL(50)) was synthesized and used as an additive to enhance the enzymatic hydrolysis of corn stalk. The addition of JLQKL(50) significantly improved the enzymatic hydrolysis efficiency, reaching 78.88% after 24 hours at a concentration of 2 g/L. JLQKL(50) also extended the pH and temperature ranges for enzymatic hydrolysis and reduced nonproductive adsorption of cellulase, resulting in improved longevity and stability of the cellulase. This study provides a basis for the development of sustainable lignin-based additives to enhance the enzymatic hydrolysis of lignocellulosic biomass.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
