Summary: In this study, the separation of bamboo hemicellulose was successfully achieved via a one-step freeze-thaw-assisted alkali treatment (OFT/AT). The selectivity of hemicellulose separation was improved, leading to a higher separation yield compared to conventional freeze-thaw-assisted alkaline treatment (FT/AT). The inhibition of lignin and cellulose separation was observed as the alkali concentration decreased, while the extraction yield of hemicellulose increased. Structural analysis revealed that the extracted hemicellulose had a relatively complete molecular structure, providing theoretical support for efficient hemicellulose separation by alkali treatment.

Summary: Xylan was enzymatically hydrolyzed to produce xylooligosaccharides (XOS) using lignocellulosic biomass or solubilized xylan as the substrate. The enzymatic hydrolysis of solubilized xylan resulted in a higher yield and concentration of XOS compared to the enzymatic hydrolysis of partial delignified biomass. Partial delignification and milling of biomass improved enzymatic hydrolysis, leading to increased conversion. The molecular weight and polydispersity of xylan decreased after hydrolysis, but increased after the second hydrolysis cycle.

Summary: The effects and mechanisms of light salting on quality properties of tilapia fillets during repeated freezing-thawing were evaluated in this study. It was found that light salting improved water-holding capacity and slowed down texture softening in tilapia fillets. Unlike the control groups with tissue distortion and heterogeneous aggregates, light salting promoted myofibril disassembly and formation of an ordered protein network. The structural rearrangement caused by light salting facilitated the enlargement of water-holding space, transformation of tissue water, and tissue recoverability, improving water-holding capacity and texture properties of tilapia fillets during freezing-thawing.

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: A novel modified cellulase with enhanced activity, stability and lignin-resistant ability was synthesized through chemical modification using hydrophilic and negatively charged polyethylene glycol derivatives. Both modifications significantly increased cellulase activity by 37% (HO-PEG-COOH modification) and 53% (HOOC-PEG-COOH modification) respectively. The modified cellulases also exhibited improved stability, with higher activities at all selected temperatures and pH values. The modifications resulted in exterior movement of tryptophan residues and improved secondary structure compactness, leading to enhanced substrate recruitment and hydrolysis initiation, as well as increased stability. The high hydrophilicity, negative charge and compactness of the enzyme conferred good lignin adsorption and destruction resistance, improving the enzymatic hydrolysis of corn stover.

Summary: Organic acid pretreatment is an effective method for separating lignocellulosic biomass, but lignin repolymerization hinders the process. A new organic acid pretreatment using levulinic acid was studied to overcome this issue. Optimal conditions for hemicellulose separation were determined at a levulinic acid concentration of 7.0%, temperature of 170 degrees C, and time of 100 minutes. The use of levulinic acid led to a significant increase in hemicellulose separation compared to acetic acid pretreatment, attributed to the inhibitory effect of gamma-valerolactone on lignin repolymerization.

Summary: Accurate analysis of the main chemical components of oil-bearing sludge is crucial for soil remediation and resource reuse. However, the interference of SAR and asphaltene during chloroform extraction makes it difficult to achieve precise analysis of extract components. In this study, n-heptane was used to efficiently extract SAR while retaining asphaltene in soil. The maximum yield of SAR extraction was 27.0%, showing an increase compared to chloroform extraction. The extracted SAR components were successfully separated and analyzed, providing a new method for component analysis of oily sludge and promoting efficient separation.

Summary: In this study, FeNi DHBQ/NF catalyst was synthesized using the redox-active ligand 2,5-dihydroxy-1,4benzoquinone (DHBQ) and exhibited excellent catalytic activity in the oxygen evolution reaction. The research confirmed that the doping of Fe in MOFs enhanced electron transfer and reduced the d-orbital crystal field splitting energy of Fe3+. It was also found that the rate-determining step in the OER process was the formation of O*, and Fe and redox-active ligands effectively regulated the adsorption energy of oxygen intermediates, reducing the energy barrier. Additionally, the redox-active ligands acted as electron reservoirs, facilitating the oxidation of Ni at low potentials and benefiting the OER process.
