In this study, through integrating inner filter effect (IFE) into antenna effects, a response approach with fluorescence and colorimetric dual signals was constructed for portable sensing of TCs based on metal-organic framework (MOF)-based nanoprobe, i.e., NH<sub>2</sub>-MIL-101(Fe)-Eu<sup>3+</sup>. With this strategy, TCs first quenches the blue fluorescence of nanoprobe by IFE and subsequently excites sharp red fluorescence of Eu<sup>3+</sup> through antenna effect, achieving the bimodal response in one fluorescence spectrum. Notably, the complexation of TCs and nanoprobe promotes electron transfer between Fe(Ⅲ) and Fe(Ⅱ), enhancing the peroxidase-like activity of the nanoprobe for specific colorimetric evaluation of TCs with assistance of 3,3′,5,5′-tetramethylbenzidine (TMB) indicator.

PT-LK demonstrated a broad-spectrum bactericidal effect on various spore-forming bacteria, in addition to a pronounced spore inactivation effect across diverse foods. Furthermore, the morphological results showed that the spores displayed blast-like openings on surface. LK was found to enter the spore core and destroy the core area.

High-performance liquid chromatography (HPLC) analyses indicated that processing at 200 MPa and 80 °C did not significantly impact the stability of LK. Moreover, under the conditions of 200 MPa and 80 °C were found to enhance the binding affinity between LK and the spore coat protein CotE, thereby enhancing its biological activity. Finally, the biosafety profile of LK was evaluated. In vitro cytotoxicity was evaluated using RAW264.7 macrophages, while antimicrobial activity was assessed against beneficial gut bacteria. The results demonstrated that LK at a concentration of 100 μg/mL exhibited no significant cytotoxic effects and negligible antibacterial activity against beneficial gut bacteria.

The accumulation of BAs commonly occurs under unhygienic conditions during raw material preparation, improper storage, and uncontrolled fermentation. BAs can be degraded by certain microorganisms through oxidative deamination activity. In this study, factors influencing the degradation of BAs by strain SK35-1, isolated from fish sauce fermentation, were examined. In addition, the ability of strain SK35-1 to mitigate histamine buildup during salted fish fermentation was assessed. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that SK35-1 shares 100 % similarity with <em>Halalkalibacterium halodurans</em>. The strain exhibited efficient degradation of BAs, ranked in descending order as follows: putrescine ≈ cadaverine > tyramine > tryptamine > histamine > spermidine > spermine. Optimal conditions for BA reduction were identified as 30 °C–40 °C, pH 6–8, and 10 % NaCl when cultivated in modified Møller broth. BA degradation was notably more effective at lower initial BA concentrations. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) zymography revealed a 45.7-kDa amine oxidase with activity against putrescine, cadaverine, spermidine, and spermine. The presence of amine dehydrogenase activity specific to histamine was confirmed through native-PAGE and enzyme assays. In salted anchovy fermentation, samples inoculated with <em>H. halodurans</em> SK35-1 exhibited a 19.7 % reduction in histamine levels compared to the uninoculated control. In addition, <em>H. halodurans</em> SK35-1 modulated volatile compound formation in fermented anchovy by suppressing off-odor compounds such as methyl thioacetate, while enhancing distinct volatiles of fermented fish, including 2-methyl-1-butanol, 3-methyl-1-butanol, 1-penten-3-ol, and 3-methyl-butanoic acid.
