Terpenes and essential oils are commercially important materials, owing to their extensive antibacterial, antifungal, membrane permeation-enhancing, and antioxidant properties, as well as their use as flavors and fragrances. Yeast particles, 3-5 m hollow and porous microspheres, are a consequence of some food-grade yeast (Saccharomyces cerevisiae) extract manufacturing processes. Their high capacity for encapsulating terpenes and essential oils (reaching up to 500% by weight), combined with sustained-release and stability properties, makes them a valuable tool. This review delves into encapsulation techniques used in the preparation of YP-terpenes and essential oils, with a broad potential for applications within the agriculture, food, and pharmaceutical sectors.

The pathogenicity of foodborne Vibrio parahaemolyticus warrants serious global public health consideration. The current study focused on optimizing the liquid-solid extraction method for Wu Wei Zi extracts (WWZE), identifying their key components, and evaluating their anti-biofilm efficacy against Vibrio parahaemolyticus. Applying both single-factor analysis and response surface methodology, the optimized conditions for the extraction process were determined as 69% ethanol concentration, 91°C temperature, 143 minutes, and a liquid-to-solid ratio of 201 mL/g. Following high-performance liquid chromatography (HPLC) analysis, the primary active constituents of WWZE were identified as schisandrol A, schisandrol B, schisantherin A, schisanhenol, and schisandrin A-C. A broth microdilution assay showed that the minimum inhibitory concentration (MIC) of schisantherin A in WWZE was 0.0625 mg/mL, whereas schisandrol B's MIC was 125 mg/mL. The MICs for the other five compounds were all higher than 25 mg/mL, confirming that schisantherin A and schisandrol B are the main antibacterial compounds found in WWZE. The effect of WWZE on the V. parahaemolyticus biofilm was investigated using various assays, including crystal violet, Coomassie brilliant blue, Congo red plate, spectrophotometry, and Cell Counting Kit-8 (CCK-8). The data highlighted a dose-dependent inhibition of V. parahaemolyticus biofilm by WWZE, both in its ability to inhibit the formation and remove existing biofilms. This involved significant damage to the cell membrane, a reduction in the synthesis of intercellular polysaccharide adhesin (PIA), disruption of extracellular DNA secretion, and a decrease in the metabolic activity of the biofilm. This study highlights the novel anti-biofilm effect of WWZE on V. parahaemolyticus, offering a basis for more extensive applications of WWZE in safeguarding aquatic food items.

In the early identification and treatment of hepatocellular carcinoma (HCC), Glypican-3 (GPC3), an emerging biomarker, has demonstrated positive results. An ultrasensitive electrochemical biosensor for GPC3 detection, based on a hemin-reduced graphene oxide-palladium nanoparticles (H-rGO-Pd NPs) nanozyme-enhanced silver deposition signal amplification strategy, was constructed in this study. Gpc3 interacting with its antibody (GPC3Ab) and aptamer (GPC3Apt) created an H-rGO-Pd NPs-GPC3Apt/GPC3/GPC3Ab sandwich complex. This complex exhibited peroxidase-like catalytic activity, accelerating the reduction of silver ions (Ag+) in hydrogen peroxide (H2O2), resulting in the deposition of metallic silver nanoparticles (Ag NPs) onto the surface of the biosensor. The differential pulse voltammetry (DPV) method served to ascertain the amount of deposited silver (Ag), which was directly related to the amount of GPC3. For ideal circumstances, the response value's correlation with GPC3 concentration, measured at 100-1000 g/mL, exhibited an R-squared value of 0.9715, indicating a strong linear relationship. A logarithmic trend was observed between the GPC3 concentration (ranging from 0.01 to 100 g/mL) and the response value, with a high degree of correlation indicated by an R2 value of 0.9941. At a signal-to-noise ratio of three, the limit of detection was 330 ng/mL, while the sensitivity reached 1535 AM-1cm-2. The electrochemical biosensor's effectiveness in detecting GPC3 in serum samples was verified through good recoveries (10378-10652%) and satisfactory RSDs (189-881%), underscoring its suitability for real-world applications. This investigation introduces a new method for evaluating GPC3 levels, which is crucial for the early identification of hepatocellular carcinoma.

Catalytic conversion of CO2 with the extra glycerol (GL) from biodiesel production has sparked significant interest across academic and industrial domains, demonstrating the crucial need for catalysts that exhibit superior performance and offer substantial environmental advantages. Employing titanosilicate ETS-10 zeolite-based catalysts, with active metal components introduced by impregnation, the coupling of carbon dioxide (CO2) and glycerol (GL) was carried out to efficiently produce glycerol carbonate (GC). On Co/ETS-10, utilizing CH3CN as a dehydrating agent, the catalytic GL conversion at 170°C spectacularly achieved 350% conversion, resulting in a 127% GC yield. In a parallel examination, Zn/ETS-Cu/ETS-10, Ni/ETS-10, Zr/ETS-10, Ce/ETS-10, and Fe/ETS-10 were similarly prepared and showed weaker coordination of GL conversion and GC selectivity. A systematic investigation uncovered that the presence of moderate basic sites critical to CO2 adsorption-activation was integral to modulating catalytic activity levels. Moreover, the significant connection between cobalt species and ETS-10 zeolite was of substantial importance in improving glycerol's activation capacity. A plausible mechanism for the synthesis of GC from GL and CO2 was proposed, using CH3CN as a solvent and a Co/ETS-10 catalyst. A further investigation into the recyclability of Co/ETS-10 demonstrated its capability for at least eight recycling cycles, with minimal loss, less than 3%, of GL conversion and GC yield following a straightforward regeneration process involving calcination at 450°C for 5 hours in air.
