Summary: Differentiated Lactococcus lactis bacteriocin producers' strains using repPCR technique. The stability of bacteriocin was found to be influenced by applied chemicals, pH, and temperature. The addition of bacteriocin completely inhibited the growth of Listeria monocytogenes ScottA, Lactobacillus sakei ATCC 15521, or Enterococcus faecium ATCC 19434 in the study.

Summary: In this study, the inhibitory effects of antimicrobial peptides produced by Lactococcus lactis L2 on pig pathogens were tested. The peptides showed good bacteriostatic and bactericidal effects, especially against Gram-positive bacteria, and their low molecular weight may be responsible for their antimicrobial properties. The use of probiotics in controlling pig pathogens has potential benefits.

Summary: The food industry faces the challenge of producing healthy and safe food products, leading researchers to focus on natural antimicrobial compounds such as bacteriocins due to consumer concerns about chemical preservatives. Pediocins, small unmodified peptides with low molecular weight, exhibit broad spectrum antimicrobial activity against Gram-positive bacteria, especially pathogenic bacteria like Listeria monocytogenes.

Summary: Subtilin JS-4 is a highly effective antibacterial peptide against the foodborne pathogen Listeria monocytogenes, showing good thermal and pH stability and a broad antimicrobial spectrum against Gram-positive bacteria. Its antibacterial mechanism involves increasing cell membrane permeability, triggering ion leakage and pore formation, damaging cell membrane integrity, and altering cell morphology and intracellular organization.

Summary: Bacteria have been used as vectors for vaccines and therapies for decades, but the diversity of strains used has been limited. Advances in immunology and genetic tools have expanded our ability to engineer bacteria using various delivery strategies. Each delivery strategy requires specific considerations, optimization, and safety concerns depending on the application.

Summary: Human zoonotic infection with Campylobacter and Listeria monocytogenes, leading to gastroenteritis and potentially fatal infection, respectively, are often associated with contaminated food. This study identified a strain of endospore-forming bacterium that demonstrated bactericidal effect on both pathogens. The bactericidal effect was attributed to secretions from the spore former. Further analysis indicated the potential of using this strain as a feed additive for controlling Campylobacter in poultry.

Summary: Lactococcus lactis, specifically the subsp. cremoris Y15 strain, has shown various technological characteristics and antibacterial activity that make it suitable as a starter culture for the production of Cheddar cheese. This strain exhibits high acidification, proteolytic activity, diacetyl production, and autolytic ability. It also possesses strong antibacterial activity. The texture and sensory acceptability of Cheddar cheese produced using L. lactis subsp. cremoris Y15 are comparable to those produced using other starter cultures.

Summary: Listeria monocytogenes is a potentially deadly pathogen that can be controlled using a fermentate produced by nisin-producing Lactococcus lactis strain. A transposon screen was used to isolate a nisin-negative mutant which demonstrated a complete loss of anti-L. monocytogenes activity, showing the importance of nisin production in controlling this pathogen.

Summary: This study demonstrated that carvacrol has significant inhibitory effects on biofilms of Pseudomonas aeruginosa and Listeria monocytogenes, showing reductions in biofilm formation on both MBECTM biofilm device and polypropylene surface. Visual observations using advanced microscopy confirmed the results, suggesting the potential use of carvacrol as a natural compound to prevent contaminations of food contact surfaces by these bacteria.

Summary: This study aims to develop a synergistic approach to better control Listeria biofilms using nisin, in combination with gallic-acid-rich food plant extracts. The results showed that gallic acid significantly decreased the level of biofilm formation in L. monocytogenes, while ethyl gallate, propyl gallate, and lauryl gallate enhanced biofilm production. Sage extracts enhanced the antibiofilm activity of nisin against L. monocytogenes, but the other extracts increased biofilm formation.

Summary: The current study aimed to screen bacteriocin producing LAB from different dairy products and evaluate their biological properties. Among the isolated LAB species, one strain (CH3) showed better antimicrobial effects and its purified bacteriocin demonstrated strong antimicrobial and anti-biofilm activity against selected human pathogens. These findings suggest the potential application of bacteriocin in combating antimicrobial-resistant pathogens and preserving food without contamination.

Summary: This study demonstrates the antibacterial activity of phenyllactic acid (PLA) against Staphylococcus aureus and its potential application in dairy products. PLA inhibits the growth and biofilm formation of S. aureus, and it exerts antibacterial effects by affecting the cell metabolism, membrane integrity, intracellular content leakage, oxidative stress, and morphological deformation of S. aureus. The antibacterial effects of PLA against S. aureus cells in skim milk and cheese are maintained during storage for 21 days at 4 degrees C.
