Summary: Ionic liquids, specifically PILs, have shown potential in selectively solubilizing lignin and enabling high yield and productivity in fermentation processes. The design of PILs influences lignin characteristics, while pretreatment temperature and time do not. The recovered lignins are sulfur-free and have functional groups that make them suitable for conversion into various value-added products in a biorefinery context.

Summary: This study investigated the effect of ultrasound-assisted hydrogen peroxide (H2O2) pretreatment on sugar cane bagasse (SCB) followed by Monascus purpureus TISTR 3003 cultivation for lovastatin production under solid-state fermentation (SSF). The optimization results showed that the lovastatin production was 2347.10 +/- 17.19 mu g/g under the optimum conditions, which is 2.4 times higher than that under untreated conditions. Scanning electron microscopy analysis revealed changes in the surface structure of the treated SCB.

Summary: This study utilized acetone/phenoxyethanol/water (APW) solutions to pretreat sugarcane bagasse and improve sugar production in enzymatic hydrolysis. The optimal pretreatment conditions were determined to be 125 degrees C-120 min, 0.17 M H2SO4, and a liquid-solid ratio of 15, resulting in high lignin removal and cellulose digestibility. The APW process also showed effective fractionation of other biomass feedstocks, such as pine, corn stalk, and bamboo.

Summary: The particle size, distribution, and microstructure of cement have a significant impact on the mechanical and durability properties of mortar and concrete. The mechanical properties and microstructure of Original Sugar Cane Bagasse Ash (OSCBA) can be improved after treatment. Parameters such as grinding conditions and burning process influence the morphological characteristics. Blending treated and untreated bagasse ash with cement can significantly improve the performance of the blended cement.

Summary: Ultra-high-performance concrete (UHPC) is a research focus in cementitious materials due to its excellent mechanical properties and durability. However, high production cost limits its development. Sugar cane bagasse ash (SCBA), with pozzolanic characteristics, has been studied as an alternative cementitious material. This study used SCBA as an active filler to replace quartz powder (QP) in UHPC and found that it improved the strength through pozzolanic reaction and internal curing, reducing production cost and environmental impact.

Summary: This study investigated the microstructural characteristics of sugar cane bagasse ash (SCBA) and the feasibility of replacing cement with SCBA in cement mortar. The findings suggest that replacing cement with SCBA above 10% leads to dry mix and incomplete hydration process, resulting in decreased strength. Consistency of cement increases with higher percentages of SCBA, while compressive strength peaks around 10%, showing better results than samples with constant consistency.

Summary: This study evaluated the optimization of enzymatic hydrolysis cocktail to maximize sugar extraction from pretreated sugarcane bagasse. It was found that adding hydrogen peroxide at the beginning of hydrolysis increased glucose and xylose concentrations, while the addition of hemicellulase increased glucose and xylose production. These findings suggest that using an appropriate enzymatic cocktail supplemented with additives can enhance sugar extraction from lignocellulosic biomass and contribute to the development of a more sustainable and competitive process.

Summary: In this study, maleic acid was used to pretreat Kenaf stalk lignocellulosic biomass and produce light-colored dissolved lignin. The lignin was further transformed into lignin nanospheres for use in sunscreens. The lignin-based sunscreen showed a significantly higher sun protection factor than commercially available sunscreens. Moreover, the remaining solid after pretreatment was utilized to produce Kenaf fibers, which improved the strength and durability of paper.

Summary: Black liquor, a by-product of the pulping process, can be used as an energy source to produce biofuels and value-added chemicals. However, its industrial applications are limited due to its insolubility in water and lack of reactivity. This study focused on modifying alkali lignin from bagasse through sulfonation, sulfomethylation, and amination processes. The results showed that the modification improved the water solubility and thermal stability of lignin, making it more suitable for industrial applications.

Summary: This study investigated the effect of solvent on the stability of bio-oils produced from the hydrothermal liquefaction of sugarcane bagasse. It was found that the ethanol/water solvent mixture produced the most stable bio-oil compared to other solvents. The light oils fractionated by solvent extraction were also more stable than their corresponding bio-oils. The stabilities of the oils were related to alkylation, esterification, and acetalization reactions. This study demonstrated that the HTL of sugarcane bagasse in the presence of ethanol/water produces high-quality oils with long shelf-lives.

Summary: Through temperature-regulated linker thermolysis, MIL-121 was transformed into hierarchically porous MOF variants with increased average pore size (up to 61.8 Å) and specific surface area (up to 346.2 m2/g). The surface functionality and defects were improved, leading to enhanced adsorption of dyes. The adsorption mechanisms were explained using pseudo-second order and Langmuir models, and the thermodynamic studies showed the spontaneous nature of the adsorption. The improved textural and functional properties of MIL-121-500 were responsible for the enhanced adsorption of dyes.

Summary: The lignin structure of orange tree pruning (OTP) residue was examined. The OTP-MWL mainly consisted of guaiacyl (G) units with minor amounts of syringyl (S) and p-hydroxyphenyl (H) units. The lignin contained various linkages, including beta-O-4 ' alkyl-aryl ethers, phenylcoumarans, resinols, dibenzodioxocins, and spirodienones. The presence of condensed linkages makes the lignocellulosic residue more recalcitrant to delignification.

Summary: In this study, various artificial copolymers of monolignols and hydroxystilbenes were synthesized and characterized to investigate their incorporation into the lignin polymer. The copolymerization of hydroxystilbenes with monolignols, using peroxidases as catalysts, significantly improved the reactivity of monolignols and resulted in the formation of synthetic lignins. Analysis using NMR and model compounds confirmed the involvement of hydroxystilbenes in the oxidative radical coupling reactions during polymerization.

Summary: Lignins released in black liquors from kraft pulp mills are a valuable but underutilized source of aromatics. Enzymatic depolymerization of kraft lignins using alkaliphilic fungal laccases has been made possible by our recent enzyme-directed evolution approach, which generated laccases with high activity and stability at pH 10. Our study demonstrates the ability of these tailor-made laccases to oxidize, demethylate, and depolymerize eucalyptus kraft lignin at pH 10. However, in high enzyme and lignin concentrations, repolymerization of the oxidized products becomes dominant. To overcome this, we successfully conducted the enzymatic reaction in a bench-scale reactor coupled to a membrane separation system.

Summary: With the increasing awareness of a circular economy, utilizing all components of lignocellulosic biomass to maintain sustainability becomes necessary. In this study, the one-step conversion of hemicellulose in sugarcane bagasse to xylooligosaccharides (XOS) was selectively targeted while preserving cellulose and lignin. Additionally, plasma treatment of carbon materials was pursued as a global effort to produce metal-free carbon-based catalysts. The functionalized activated carbon (AC) achieved high yields of XOS and xylose, demonstrating its potential as a facile method for the depolymerization of hemicellulose from lignocellulosic biomass.
