Summary: Aeration of water contaminated with PFASs can effectively separate and concentrate PFAS through adsorptive bubble fractionation. This study investigated the impact of changes in environmental and process parameters on PFAS removal efficiency and found that bubble fractionation can achieve high levels of overall PFAS removal (>95%) across a wide range of saline and temperature conditions. The removal of certain short-chain PFAS species was improved by increased electrolyte concentration and decreased temperature. However, higher temperature slightly reduced the total PFAS removal rate (to 93%). These findings demonstrate the viability of bubble fractionation as a primary step for PFAS removal in contaminated water.

Summary: This study developed a surfactant-free active Al2O3 nanoparticle (ANP) modified with adipic acid (AA) as a collector and frother for efficient recovery of anthocyanin (ACN) from perilla leaves. The ANP-AA had a high collection capacity for ACN and formed a stable foam layer at the gas-liquid interface. Under appropriate conditions, ACN recovery of 95.68% with an enrichment ratio of 29.87 was achieved. The recovered ACN also exhibited promising antioxidant properties, highlighting the significance of these findings in the food, colorant, and pharmaceutical industries.

Summary: Mushroom-forming fungi, particularly basidiomycetes, degrade plant materials efficiently with lignin-, cellulose-, hemicellulose-, and pectin-degrading enzymes. The transcription factor Cre1 plays a crucial role in regulating these enzymes through carbon catabolite repression (CCR), as demonstrated in Coprinopsis cinerea. Deletion of the cre1 gene resulted in significant deregulation of carbohydrate metabolism, PCWDEs, and other genes, highlighting its importance in regulating gene expression related to plant biomass degradation. The study expands our understanding of CCR in Basidiomycota and provides insights into genes involved in lignocellulosic biomass degradation.

Summary: The transcription factor CcNsdD2 in Coprinopsis cinerea promotes primary hyphal knot formation by upregulating cfs1, cfs2, cgl1, and hyd1. The developmental fates of primary hyphal knots mediated by CcNsdD2 depend on light/dark rhythm cultivation or dark cultivation after full growth of mycelia. This study provides new insights into the molecular mechanism by which CcNsdD2 regulates the developmental fate of C. cinerea under dark or light conditions, with potential applications in the edible mushroom industry.

Summary: In this study, the separation of volatile organic compounds (VOCs) from a highly viscous polymer solution was investigated using rotating packed bed (RPB) technology. The results showed that the pressure in the RPB had the greatest impact on VOC content, while the rotational speed had a minor effect. By using countercurrently flowing stripping gas, the VOC content and separation efficiency were significantly reduced, making RPB technology a breakthrough for purification of highly viscous liquid mixtures.

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.
