Summary: The LS7247 strain of Ligilactobacillus salivarius has shown high probiotic potential against Salmonella Enteritidis and Salmonella Typhimurium, with high tolerance to gastric and intestinal stress and strong anti-Salmonella activity. It produces a high concentration of lactic acid and bacteriocins, which contribute to its antimicrobial properties. The cell-free culture supernatant of LS7247 has been shown to inhibit the adhesion of Salmonella pathogens to human and animal enterocytes, and when combined with the prebiotic Actigen, it demonstrates a significant combined effect in inhibiting adhesion.

Summary: This study introduces novel modified rice protein (MRP)-ammonium shellac (NH4SL) enteric composite coatings to protect probiotics during storage, thermal treatments, and simulated gastrointestinal digestions. The MRPpH13-NH4SL suspension showed better stability than other suspensions due to the improved solubility and stability of MRP at a higher pH. Overall, the composite coatings significantly enhanced the viability of probiotics in various conditions, making them a promising option for probiotic-containing products.

Summary: The call to cater for the hungry is a worldwide problem in the 21st century. Food security is the utmost prime factor for the increasing demand for food. Awareness of human health when using chemical preservatives in food has increased, resulting in the use of alternative strategies for preserving food and enhancing its shelf-life. Bacteriocins, particularly those produced by lactic acid bacteria (LAB), have gained importance for their antibacterial properties and their association with food fermentation. Circular bacteriocins, with their stable circular structure, have been less studied but offer potential applications in the food industry for extending shelf-life.

Summary: Environmental monitoring programs (EMP) are essential for ensuring food safety, but knowledge about monitoring practices is not widely disseminated. This survey collected information on monitoring practices in the French agri-food industry and found that EMP strategies are based on risk management. The lack of guidance and the need to balance standardization with site-specific characteristics were identified as challenges.

Summary: This study investigated the growth kinetics of foodborne pathogen B. cereus during the commercial production of liquid egg yolk using PLA(2) treatment. The results showed that B. cytotoxicus NVH391-98 can grow prolifically at 50 degrees C, with estimated minimum, optimum, and maximum temperatures of 16.7-18.5, 47.8-48.1, and 52.1-52.4 degrees C, respectively. The dynamic model was validated with isothermal curves and it was found that holding the temperature below 15 degrees C or above 55 degrees C can effectively prevent the growth of B. cytotoxicus in egg yolk.

Summary: The infection mechanisms of Arcobacter are still uncertain. This study found that Arcobacter isolates from food and water sources were able to adhere and invade Caco-2 cells, and carried at least two virulence markers. A. butzleri showed higher virulent activity compared to A. cryaerophilus, while A. lanthieri, A. skirrowii, and A. vitoriensis exhibited even higher adhesion and invasion values. Sewage isolates were more adherent and invasive, and had a higher gene content. The association between cadF and hecA with high adhesion capability was identified for the first time.

Summary: Interactions between bacterial species in the formation of dual-species biofilms in the food industry are affected by environmental stresses, such as temperature and pH. This study found that the combination of cold and acid stresses significantly increased biofilm formation, and different temperatures resulted in variations in the presence of specific bacterial species and the secretion of extracellular substances. The findings provide valuable insights for addressing mixed biofilms in food processing under diverse stressful conditions.

Summary: This research investigates the role of flagella-related genes in the adhesion of E. coli O157:H7 and the effects of certain cations on bacterial adhesion and motility. The results demonstrate that flagellar-mediated motility is critical in the early stage of adhesion, and the presence of Fe2+, Ca2+, and Mn2+ affects the adhesion and motility of wildtype strains but not flagellar function-impaired strains. These findings provide new insights into the mechanisms of bacterial adhesion and have implications for the development of anti-adhesion agents.
