Summary: The main objective of this study was to isolate and determine the potential probiotic properties and enzyme production of several strains of lactic acid bacteria (LAB). The results showed that two LAB isolates exhibited antimicrobial activity against certain pathogenic strains and displayed favorable characteristics for survival and growth. Additionally, these isolates also demonstrated enzymatic activities, with one producing lipase and the other producing amylase and protease.

Summary: This study aimed to screen and characterize potential probiotic strains of Bacillus spp. from the gut of Rhynchocypris Lagowskii. The isolated Bacillus licheniformis (LSG1-1) and Bacillus subtilis (LSG2-1) showed good tolerance and adhesion abilities, and exhibited significant inhibitory effects on Aeromonas pathogens. These strains could serve as potential probiotics for disease control in aquaculture.

Summary: In this study, recombinant lactoferrins (rLFs) were successfully expressed in selected probiotic strains, enhancing their antibacterial activities against important food-borne pathogens. The strategy provides a simple method for functional LF production in both functional and LF-resistant hosts.

Summary: An Ag/TiO2 coating was deposited onto glazed ceramic tiles at high temperatures using a sol-gel and spraying method. The coating showed higher antibacterial activity and adhesion, providing a solution to address low photocatalytic activity at high temperatures and poor adhesion at low temperatures.

Summary: A patented strain of Bacillus amyloliquefaciens C-1 in our laboratory has been found to produce functional sodium selenite under optimized fermentation conditions. This strain, known as C-1, has the ability to synthesize selenium nanoparticles and has shown potential as selenium-enriched postbiotics. The synthesized selenium nanoparticles exhibited antioxidant activity and C-1 cells enriched with selenium demonstrated anti-inflammatory effects. Transcriptome data analysis revealed differential gene expression in C-1 with and without selenium-enrichment, suggesting the involvement of various genes related to ABC transporter proteins and selenium metabolism. This study provides valuable insights for the development of nano-selenium biomaterials and selenium-enriched postbiotics.

Summary: A new strain of Lactobacillus taiwanensis, CLG01, was isolated from mouse Peyer's patches and characterized for its probiotic properties. The complete genome of strain CLG01 was sequenced, revealing its tolerance to acid, bile salt, and antibacterial activity. In vitro studies showed that CLG01 can enhance immune responses and upregulate expression of TNF-alpha and IL-6 in mouse RAW 264.7 macrophage cells. The genome of CLG01 also contains genes related to stress resistance and biosynthetic gene clusters encoding antimicrobial peptides.

Summary: Previous studies have shown that Lactobacillus paracasei has significant in vitro cholesterol-lowering abilities. This study evaluated the antibacterial properties, safety, and probiotic aptitude of L. paracasei in rats. The results demonstrated that L. paracasei exhibited high antibiotic resistance, good autoaggregation ability, and had the potential to lower cholesterol and inhibit the growth of Escherichia coli and Staphylococcus aureus. Overall, L. paracasei is a safe and effective supplement for Wistar rats.

Summary: In this study, alginate-nisin (Alg-N) was used as a coating layer to encapsulate Pediococcus acidilactici, a potential probiotic-protective lactic acid bacteria (LAB) isolate, to improve its survival and antibacterial activities. The size of the Alg and Alg-N microcapsules was determined to be 762.63 μm and 501.77 μm, respectively. Zeta potential data confirmed the presence of the Alg-N surrounding layer. Fourier transform infrared findings revealed the adsorption of nisin on the Alg beads. The microcapsules exhibited significantly higher antibacterial activity against Staphylococcus aureus compared to other foodborne bacteria studied, and the viability of the encapsulated LAB in simulated gastrointestinal conditions and flavored milk was improved.

Summary: In this paper, Ag NWs@BaTiO3 core-shell composites with good biocompatibility, low cytotoxicity, and high antibacterial efficiency under harsh conditions were presented. The continuous co-disturbances induced by ultrasound and light disrupted the electrostatic balance and saturation effects of the triple internal electric field on the composites, increasing its affinity and adhesion to bacterial cells. The antibacterial efficiency of the composites against S. aureus and E. coli reached 92.5% within 60 min and close to 100% within 30 min under low-power visible light irradiation and ultrasonic vibration, respectively.

Summary: The use of probiotics can improve skin conditions by competing for adhesion sites with pathogenic bacteria, inhibiting their invasion and adhesion, and preventing colonization. Recent studies have shown that probiotics can effectively improve various skin disorders such as atopic dermatitis, acne, eczema, and psoriasis.
