This study aimed to elucidate the antibacterial mechanism of LAB-4 against Gram-positive bacteria at the cellular and molecular levels. A series of <em>in vitro</em> assays (including antibacterial activity, safety, stability, membrane integrity, and membrane permeability analyses) and computational simulation techniques (molecular docking and molecular dynamics simulations) were employed to systematically investigate the antibacterial efficacy and mechanism of LAB-4. The results showed that LAB-4 exhibited potent antimicrobial activity, rapid bactericidal effects, minimal hemolytic activity, no cytotoxicity, and high stability under various adverse conditions. <em>In vitro</em> assays revealed that LAB-4 inhibited bacterial growth in a concentration-dependent manner, primarily causing irreversible membrane damage in Gram-positive bacteria by disrupting membrane integrity, increasing membrane permeability, and inducing intracellular content leakage. Computational simulations indicated that LAB-4 initially bound to peptidoglycan, after which its positively charged amino acid residues (primarily Arg, His, and Lys) were drawn to negatively charged membrane phospholipids through electrostatic interactions and extensive hydrogen bonding. LAB-4 subsequently inserted into the phosphatidyl-phosphate headgroups of the POPG and POPE bilayers via hydrophobic interactions, causing an increase in the area per lipid and a decrease in the membrane thickness. These findings demonstrated that LAB-4 exerted its antibacterial effect by inducing membrane disruption and underscored its potential as a safe and effective natural antimicrobial agent for applications in the food industry.</div></div>","PeriodicalId":12409,"journal":{"name":"Food Bioscience","volume":"71 ","pages":"Article 107101"},"PeriodicalIF":4.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144312963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To identify the most suitable green solvent for extracting the target compounds, the COSMO-SAC thermodynamic model was employed, providing a predictive and sustainable approach to solvent selection. Subsequently, the extracted betalains were incorporated into bacterial coatings. Antioxidant capacity, evaluated via DPPH and ABTS assays, showed significant enhancement in radical scavenging activity for coated strains compared to uncoated controls (10–20 %). Coatings containing Btc from <em>B. vulgaris</em> and the reference compound catechin achieved the highest antioxidant performance, reaching ∼85 % scavenging. Btc-based coatings consistently outperformed Btx-based ones, with IC₅₀ values approximately three times lower for L.b strains. Viability assessments demonstrated that coatings protected and supported bacterial growth. When applied to yogurt formulations, the coated bacteria maintained their antioxidant enhancement, increasing radical scavenging activity from ∼45 % (control) to ∼63 % at the highest concentration (Sx3 = 3-fold 1–2 × 10⁹ CFU/mL), also imparting increased redness.

The deprotonation of Luteolin and its analogues into corresponding phenolates has been confirmed as effective inhibitory agents, exhibiting differential effects on superoxide production originating from XOD. However, the Stern-Volmer plots of <em>F</em>₀/<em>F</em> versus [Q] at various temperatures failed to demonstrate polynomial-linear fitting, instead approaching the X-axis to varying extents, which deviates from the anticipated good linearity. This indicates that the thermodynamics of inhibition may be concentration-dependent. At lower inhibitor concentrations, the formation of the ground-state complex is characterized by static fluorescence quenching within an accessible interaction region, as evidenced by linear-fitting plots. As the concentration increases, inaccessible interactions are observed, indicated by curves in the Stern-Volmer plots that approached the X-axis, suggesting a reduction in fluorescence quenching intensity. Furthermore, in the inhibition kinetics, Luteolin and its analogues exhibit mixed-type inhibition (both non-competitive and competitive) at higher concentrations, contrasting with non-competitive inhibition at lower concentrations. Simultaneously, the binding interaction between the inhibitor and enzyme is validated through synchronous fluorescence analysis and molecular docking simulations.

As awareness of healthy eating grows, there is a growing demand for sugar-free options, especially in baked goods. Due to its low calories, allulose (Alu) can reduce the free sugar in bread. However, compared with sucrose bread, allulose bread required a longer fermentation time to reach a similar volume. At the same fermentation time, the baking loss rate of allulose bread was reduced by approximately 21 %, while the specific volume decreased by 48.5 %. Meanwhile, the allulose bread fermented for 1 h (Alu-55-1) had high hardness and a weak Maillard reaction. The browning index (BI) of allulose bread is also very low, far less than that of sucrose bread. Extending the fermentation duration for allulose samples to 3 h (Alu-55-3) resulted in improvements across nearly all evaluated parameters of the bread, including specific volume, texture and stomatal distribution. The addition of Alu also affected the rheological properties of the dough. At high frequencies, the fluid properties of allulose dough were enhanced, and the dough was soft and viscous. In the allulose environment, the yeast grew slowly, and there was no obvious exponential phase, indicating that the yeast was inhibited by allulose.
