Summary: In this study, five acid or alkali catalyzed ethylene glycol (EG) organosolv pretreatments were proposed and compared for sugar production from bagasse. The results showed that EG/H2O-HCl pretreatment was more efficient for both hemicellulose and lignin remove, while EG/H2O-NaOH pretreatment was beneficial for lignin remove but weak for hemicellulose degradation. Both pretreatments have good capacity to reserve the cellulose in pretreated solids.

Summary: In this study, sugarcane bagasse was pretreated using a renewable organic acid (xylonic acid) derived from the biooxidation of xylose. The effects of reaction temperature and time on the release of fermentable xylose and glucose were investigated. After optimization, a pretreatment with 1% xylonic acid at 190 degrees C for 30 min was selected, resulting in a release of 70% xylose and an enzymatic hydrolysis yield of 86.5%. The pretreated hydrolysate liquor was also shown to be suitable for xylonate production through the biooxidation of Gluconobacter oxydans. Additionally, the sequential process of xylonic acid pretreatment and saccharification provides a pathway for recycling lignin as value-added bioproducts. Overall, this study presents a green-like strategy for fully utilizing sugarcane bagasse.

Summary: In this study, an HCl-catalyzed ethylene glycol (EG) pretreatment was used to enhance sugar release from sugarcane bagasse (SCB). The combination of HCl and EG effectively removed xylan (approximately 100.0%) and lignin (approximately 61.3%) from SCB, resulting in a pretreated substrate that exhibited good efficacy for subsequent enzymatic hydrolysis. The highest glucose yield achieved was 93.9% after pretreatment at 130 degrees C for 60 min with 0.5% HCl and 72 h enzymatic digestion. Surface morphology and internal composition changes were identified as the main reasons for the improved hydrolysis efficiency of SCB. Addition of Tween 80 during the hydrolysis process significantly shortened the hydrolysis time and reduced the cellulase dosage, while maintaining a relatively high glucose yield of 91.4%.

Summary: Sugarcane bagasse, a rich source of xylose, was utilized to produce xylonic acid with engineered Zymomonas mobilis. Expression of XDH gene from Paraburkholderia xenovorans led to the highest production, with deletion of xylose reductase gene further increasing yields. The findings suggest Z. mobilis could serve as a potential platform for organic acid production from cheap lignocellulosic biomass in biorefineries.

Summary: Covalent organic frameworks (COFs) are used for photocatalytic hydrogen evolution via water splitting, but water oxidation remains challenging. This study proposes a 2D/2D Z-scheme heterojunction, combining COFs and Ov-WO3 nanosheets, to improve overall water splitting. The enhanced electric field, strong water oxidation ability, and thin structure lead to significantly enhanced separation and utilization of electron-hole pairs. Impressive hydrogen evolution and overall water splitting rates are achieved on the COF-WO3 (TSCOFW) composite.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
