A major Chinese woody oil plant with unsaturated-fatty-acid-rich seeds for biodiesel and edible oil,Xanthoceras sorbifoliumtolerates drought but not waterlogging; salicylic acid (SA), a key stress response signal, is inexpensive, safe, and effective for enhancing stress tolerance. Two-year-old saplings ofXanthoceras sorbifoliumwere used as materials. They were sprayed with 0.5 mmol·L−1SA for 3 days (based on prior studies), and then waterlogged for 10 days; physiological and transcriptomic data were collected. SA significantly increased height, diameter, and root dry weight by 392.6%, 450.0%, and 242.4% compared to water control; enhanced osmotic regulatory substances, antioxidant enzyme activities, secondary metabolites, and root activity; and reduced malondialdehyde content and relative electrical conductivity by 23.40% and 148.7%. SA-enhanced antioxidant defense correlated with synergistic transcriptional regulation. Transcriptome analysis showed that SA up-regulated key enzyme genes involved in flavonoid synthesis, such as PAL and 4CL, and regulated hormone signal transduction-related genes such as SAUR and DELLA. Key transcription factor genes were also screened, mainly including members of the MYB, bHLH, and ERF families. SA alleviated waterlogging damage. Meanwhile, this study provides valuable insights into the molecular basis of the response to waterlogging stress regulated by salicylic acid, and offers important theoretical and practical significance for the promotion and cultivation ofXanthoceras sorbifoliumin rainy southern regions of China.

Polygonatum sibiricumpolysaccharide (PsP), one of the main components ofPolygonatumsibiricumused in traditional Chinese food and medicine, has important bioactive functions, but it is difficult to fully utilize PsP because of the degradative effect of digestive gastric juices. This study aimed to innovatively synthesize a new food formulation for PsP, namely, a PsP–hydroxyapatite (HAP) sustained-release system, so as to reduce its degradation. The new food formulation was optimized and evaluated by the response surface method (RSM) and by in vitro experiments. The optimal stirrer temperature, reaction pH, etching pH, and loading time for synthesizing PsP-HAP were 85.62 °C, pH 11.12, pH 8.40, and 5.10 h, respectively, all of which were different from the findings of other similar research studies. The average encapsulation rate of PsP-HAP reached (40.16 ± 1.54)%, and the content of PsP was 8.98%. Additionally, PsP-HAP appeared to be pH-responsive, and its continuous antioxidative effect was first proven by the DPPH assay and then cytologically by a total antioxidative capacity assay. The CCK-8 assay indicated that PSP-HAP did not induce toxicity. This study successfully developed a new food formulation for PsP which appears to have the potential to reduce the degradative effect of digestive gastric juices. Thus, it is possible to achieve full utilization of PsP by using this new sustained-release food formulation.

Processing techniques determine the quality of tea. This study elucidates the impact of refiring process on Fenghuang Dancong Tea (FDT) under controlled experimental conditions by integrating sensory evaluation, non-targeted metabolomics (UPLC-MS/MS), and flavoromics (HS-SPME-GC × GC-TOF-MS). The results indicate that the decrease in polyphenols of the FDT mainly resulted from their transformation through the phenylpropanoid biosynthesis pathway during refiring, thereby reducing the bitterness and astringency of the tea while enhancing its sweetness. Although volatile diversity decreased with higher temperatures, the content of key aroma-contributing hydrocarbons and ketones peaked at 90 °C. Relative odor activity value (ROAV) analysis identified 9 key aroma compounds (ROAV ≥1), with 2-methyl-butanal, (E)-2-nonenal, 2-pentyl-furan, and 2,3-butanedione being the most impactful. This study provided a comprehensive investigation into metabolite changes during the refiring process of FDT, contributing valuable insights for precisely utilizing the refiring technique to improve the quality of tea.

To investigate the potential mechanism of resveratrol in anti-fatigue by network pharmacology and molecular docking, and to investigate the anti-fatigue efficacy of resveratrol through in vitro animal experiments. Resveratrol action targets and fatigue-related targets were obtained using various databases. The anti-fatigue targets of resveratrol were obtained using the Venn diagram, uploaded to the String database, imported into Cytoscape 3.7.1, and constructed into a Protein-protein interaction network. The target genes were then subjected to Gene ontology and Kyoto encyclopedia of gene and genome enrichment analysis. Molecular docking verification was performed on the binding ability of the core target to resveratrol. Using swimming-trained mice as exercise models, exhaustive swimming time and fatigue-related biochemical parameters were used as indicators to investigate the effects of resveratrol on exercise endurance and energy metabolism. 104 anti-fatigue targets and 10 core target genes of resveratrol were obtained. KEGG analysis enrichment included AGE-RAGE signaling pathway in diabetic complications, Human cytomegalovirus infection, and Pathways in cancer. Molecular docking showed that the core target genes TP53, PIK3R1, AKT1, PIK3CA, and MAPK1 had good binding activity to resveratrol. Animal experiments showed that resveratrol could prolong the exhaustive swimming time of endurance-trained mice (P < 0.01), decrease aspartate aminotransferase, alanine aminotransferase, uric acid, blood lactate (P < 0.01), decrease blood urea nitrogen (P < 0.05), increase the liver glycogen, muscle glycogen (P < 0.01). Conclusion: Resveratrol has the characteristics of multiple targets and multiple pathways in anti-fatigue; resveratrol can enhance exercise endurance in mice.

The performance of three-dimensional biofilm electrode reactors (3D-BERs) in hydrogen autotrophic denitrification is determined by electroactive biofilms. Herein, a self-assembled hybrid biofilm (SAHB) is developed on granular activated carbon particle electrodes by incorporating nano α-Fe2O3. The influences of operating parameters such as current, influent concentration, and hydraulic retention time (HRT) on denitrification are investigated as well as the mechanisms of SAHB-improved denitrification. The results indicate that SAHB achieves a high autotrophic denitrification rate of 4.20 mg TN/L/h under 40 mA current, 100 mg/L nitrate, and 26 h HRT, outperforming the naturally formed biofilm by 23.53%. SAHB contains more microorganisms than naturally formed biofilms, revealing that nano α-Fe2O3 is conducive to trapping free microorganisms on particle electrodes. SAHB enriches denitrification-related genes and increases corresponding enzyme activities (particularly nitrite reductase). According to metagenomic sequencing, nano α-Fe2O3 addition at a current level of 40 mA appears to favor denitrification via the nirS-dependent pathway probably due to its high affinity for cytochrome C. Metagenomic binning reveals that the microorganism associated with Zoogloeaceae (Rhodocyclales order) in SAHB may play a pivotal role in hydrogen autotrophic denitrification. This work develops a novel denitrification system, furthering our understanding of hydrogen autotrophic denitrification in 3D-BERs.

Background Oral administration offered a painless way and improved compliance for diabetics. However, the emerging GLP-1 analog peptide drugs for diabetes primarily rely on the injection route, and the development of oral dosage forms was hampered by the low oral bioavailability due to the structural vulnerability to digestive enzymes and molecule impermeability in the gastrointestinal tract. Results In this study, the non-covalent interaction between cholic acid (CA) and liraglutide (LIRA) was found and theoretically explained by molecular docking simulation. Formation of this physical complex of liraglutide and cholic acid (LIRA/CA Complex) reduced the self-aggregation of LIRA and accelerated intestinal epithelium penetration. By the anti-solvent method, LIRA/CA Complex was loaded into zein/rhamnolipids nanoparticles (LIRA/CA@Zein/RLs) with a loading efficiency of 76.8%. LIRA was protected from fast enzymatic degradation by the hydrophobic zein component. Meanwhile, Rhamnolipids, a glycolipid with surface activity, promoted endocytosis while also stabilizing the nanoparticles. The two components worked synergistically to ensure the delivery of LIRA/CA Complex to intestinal villi and improved oral absorption without disrupting tight junctions. LIRA/CA@Zein/RLs demonstrated a considerable intestinal epithelium absorption in mouse gastrointestinal section and a retention in vivo over 24 h, resulting in a significant and long-lasting hypoglycemic effect in Type 2 diabetes mice. Conclusion This study provided a promising oral delivery approach for LIRA and exhibited the potential for further translation into clinical application.

This work focused on the development of an inexpensive carbon source and the improvement of the fermentation-foam fractionation coupling system. The rhamnolipids production capacity of waste frying oil (WFO) was evaluated. The suitable bacterial cultivation of seed liquid and the addition amount of WFO was 16 h and 2% (v/v), respectively. A combined strategy of cell immobilization and oil emulsion avoid cell entrainment inside foam and improves the oil mass transfer rate. The immobilization conditions of bacterial cells into alginate-chitosan-alginate (ACA) microcapsules were optimized using the response surface method (RSM). Under the optimal conditions, rhamnolipids production using batch fermentation with immobilized strain reached 7.18 ± 0.23% g/L. WFO was emulsified into a fermentation medium using rhamnolipids as emulsifier (0.5 g/L). By monitoring dissolved oxygen, 30 mL/min was selected as a suitable air volumetric flow rate for fermentation-foam fractionation coupling operation. The total production and recovery percentage of rhamnolipids were 11.29 ± 0.36 g/L and 95.62 ± 0.38%, respectively. Graphical abstract

Phosphorus (P) management in the “water-energy-resource-nexus” in wastewater treatment plants (WWTPs) remains a longstanding challenge. P adsorption from the P-enriched digested sludge liquor (DSL) is a comparatively more practical and economically viable approach for P recovery in WWTPs. However, high concentrations of impurities in DSL might pose a negative and interferential effect on P adsorption, hindering the application of sorbents or precipitation methods. Given such a situation, highly efficient and cost-effective sorbent towards P reclamation from DSL is highly needed. Therefore, this study aims to develop a novel complex agent containing aluminum coagulant and superparamagnetic nano-sorbent (SNS) that can be used in magnetic seeding coagulation for P recovery. The complex agents with different PACl: SNS ratios showed varied turbidity removal rates and P recovery efficiencies and the optimal ratio was 15 mg PACl: 15 g SNS. PAC and SNS showed significant interaction because PAC could enhance P adsorption by shielding the interferential effect of colloidal impurities. In addition, the complex is highly regenerative, with turbidity and P removal rate stably maintained at 70–80% after 10 adsorption/regeneration cycles. The cost–benefit analysis of the dosing complex agent showed a dosing cost of 0.154 EUR/m3, admittedly much higher than the conventional magnetic seeding coagulation, which could probably be covered by the profit if the expensive and rare P product is reclaimed. This work indicated that the complex agent was superior due to its high adsorption capacity, easy separation, and repeated dosing, and therefore had the potential for P recovery from DSL.Keywords:phosphorus recovery;digested sludge liquor;magnetic seeding coagulation;superparamagnetic nano-sorbents;economic cost

In order to obtain noni juice with high yield and good quality, the effect of combined extraction technique of enzymatic treatment (EZ) and ultrasonication (US) on the overall quality of noni juice was investigated. Moreover, the extraction performance of the EZ-US combined extraction technique was compared with that of EZ-based extraction and the US-based extraction. Response surface methodology (RSM) was designed to optimize the parameters of ultrasonic treatment, by taking consideration of the extraction efficiency, quality parameters and bioactive ingredients of noni juice. The results indicated that combined ultrasonic and enzymatic treatment achieved a synergistic effect on promoting the quality of noni juice. The maximum juice yield of 67.95 % was obtained under ultrasonication for 10 min at 600 W after enzymatic treatment (EZU). In addition, EZU-treated juice exhibited the highest contents of total phenolic and flavonoid, which were 148.19 ± 2.53 mg gallic acid/100 mL and 47.19 ± 1.22 mg rutin/100 mL, respectively, thus contributing to better antioxidant activity. Moreover, the EZU treatment significantly reduced the particle size of noni juice, and improved its suspension stability and rheological properties. FTIR results indicated that the treatments did not bring major changes in the chemical structure and the functional groups of compounds in noni juice. Therefore, EZU treatment can be successfully applied to the extraction of noni juice with better nutritional properties and overall quality.

The aim of this study is to develop a new method for the preparation of Fe 3 O 4 @SiO 2 –An NPs from copperas. The core–shell structures of the nanoparticles and chemical composition have been confirmed by TEM, XRD and FTIR techniques. Fluorescence Enhancement of Fe 3 O 4 @SiO 2 –An NPs with zinc ions was investigated by fluorescence emission spectra. The results indicated that the Fe 3 O 4 NPs with a high purity (Total Fe 72.16 %) were obtained from copperas by chemical co-precipitation method and have a uniform spherical morphology with an average diameter of about 10 nm. The Fe 3 O 4 NPs coated with silica nanoparticles were prepared, and an attempt had been made that the Fe 3 O 4 @SiO 2 NPs were modified by 3-aminopropyltriethoxysilane and 9-anthranone successively. The recommended mole ratio of ethanol to water and the content of ammonia water added were 4:1 and 25 wt% respectively, which have an obviously effect on the combination of the final well-ordered MNPs with the amino functionalities and reactant components. The functionalized Fe 3 O 4 @SiO 2 –An NPs have a fluorescence property and this fluorescence effect can be enhanced with the Zn 2+ ions attachment. Meanwhile, the saturated magnetization of Fe 3 O 4 @SiO 2 –An NPs was 37.8 emug −1 at 25 °C and this fluorescent material exhibited excellent magnetic properties. A new way was therefore provided for the comprehensive utilization of the unmarketable copperas. Moreover, the functionalized Fe 3 O 4 @SiO 2 –An NPs have a big potential in environmental decontamination, medical technology and biological science.

Photocatalysis has attracted much attention as an emerging algae removal technology, but the inactivation performance is inevitably affected by the extracellular polymeric substance (EPS) produced by algae. In this study, a photocatalyst (Ag 2 O/g-C 3 N 4 ) with efficient algae inactivation is adopted to investigate the interactions with EPS, and the impact of EPS on photocatalytic algae removal is studied. The results show that EPS can adhere to the surface of Ag 2 O/g-C 3 N 4 by electrostatic force. The interaction with EPS decreases the surface zeta potential of the Ag 2 O/g-C 3 N 4 from 7.71 to −22.3 mV with the increase in EPS concentration, and the maximum ratio of particle size increases from 825 to 1281 nm. In addition, the interaction with EPS inhibits the release of Ag + in Ag 2 O/g-C 3 N 4 by half, thus, the toxicity of metal ions will be alleviated. Meanwhile, EPS can also be degraded by Ag 2 O/g-C 3 N 4 , indicating that EPS can work as a radical scavenger to protect the algae cells. Without the protection of EPS, 97.8% of algae cells are inactivated after 5 h photocatalysis. Therefore, more attention should be given to the interaction between EPS and photocatalyst to promote the design and application of the photocatalytic.

This work investigated the effects of biosurfactant at varied dose on the bioremediation of hydraulic fracturing flowback wastewater (HFFW) and explored the associated mechanism. Initially, a biosurfactant-producing strain Pseudomonas sp. CH1 was isolated from oily sludge . The glycolipid biosurfactant produced by CH1 have a critical micelle concentration (CMC) of 80 mg/L, and showed high stability over a wide range of temperature (0–120 °C), pH (4–12), and salinity (0%–16%, w/v). Addition of sub-CMC dose of biosurfactant to HFFW greatly enhanced the microbial growth and activity, upregulated the expression levels of degradation-related genes, and effectively promoted the biodegradation of n -alkanes (reduction from 272.21 to 56.93 mg/L) and PAHs (reduction from 61.6 to 16.36 μ g/L) in 7 days. The results suggested the feasibility of applying biosurfactant with sub-CMC dose to remediate HFFW and contribute significantly to the optimization of surfactant-facilitated bioremediation strategies.
