Summary: This study investigated the effects of support's surface properties on the immobilization of CGTase enzyme. It was found that the more hydrophilic Ca-TMA support exhibited better activity and reusability compared to the more hydrophobic GNP support. Analysis of the enzyme's secondary structures revealed that more beta-sheets and alpha-helix favored the production of more beta-CD. These findings provide insights for developing improved CGTase-based biocatalysts.

Summary: In this study, it was found that the insoluble beta-cyclodextrin bead polymer (BBP) effectively extracted certain mycotoxins such as citrinin, dihydrocitrinone, sterigmatocystin, zearalanone, alpha-zearalanol, and beta-zearalanol at different pH values. Ochratoxin A was most effectively removed by BBP at pH 3.0. This suggests that BBP could be a suitable mycotoxin binder for decontamination and analytical purposes.

Summary: This study investigated the lipid profiles of breast milk at different lactation stages using comparative lipidomic analyses. Significant differences in lipid composition were found between colostrum and later lactations. Colostrum was characterized by high molecular weight triacylglycerols and specific lipid species. Differential lipid species were identified as markers for distinguishing adjacent lactations. These findings deepen our understanding of human milk lipid profiles and their dynamic changes, and contribute to the development of infant formulas suitable for Chinese babies of different age groups.

Summary: This study investigates the impact of different chain lengths of hydrophilic polyglycerol fatty acid esters (HPGEs) on protein interactions and the surface and interfacial properties of low-fat aerated emulsions. The results show that samples with longer chain lengths have larger particle sizes, higher zeta-potential, and rougher surfaces. Under increased pressure, these samples form less viscoelastic structures. The M-7D sample exhibits stronger interaction with the protein, resulting in an unstable interfacial membrane.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
