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: Listeria monocytogenes is an important food-borne pathogen that can contaminate food. Traditional methods to inhibit its growth and extend food shelf life often damage food quality. Probiotics, as a biological antimicrobial method, have shown promise in effectively inhibiting the growth of L. monocytogenes. This review summarizes human listeriosis, current contamination situations, and discusses the effects and mechanisms of probiotics in inhibiting L. monocytogenes in foods. The latest applications of probiotics in dairy, meat, and fresh products are also presented and discussed.

Summary: This study examined the effect of B. coagulans cell free supernatant (CFS) on the growth of various bacteria, showing a reduction in pathogen growth and cytotoxicity. Results suggest that B. coagulans could be a potential probiotic to diminish cytotoxicity and inflammatory response of enteropathogenic bacteria.

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: This study aimed to select bacteriocinogenic strains among Enterococcus strains isolated from Ukrainian traditional dairy products. Molasses and steep corn liquor were used as a low-cost media for screening. The results showed that 34 Enterococcus strains produced metabolites that inhibited the growth of indicator strains, and five strains were found to possess enterocin genes.

Summary: This study evaluated six Lactococcus lactis and seven Lactiplantibacillus plantarum strains for their effectiveness in controlling the growth of Listeria monocytogenes in miniature fresh cheese. The results showed that five strains could be considered suitable candidates for use as protective cultures in fresh cheese manufacture, as they significantly reduced the pathogen counts.

Summary: A new bacteriocin, RSQ04, showed inhibitory effects on Listeria monocytogenes and its biofilms with excellent stability under adverse conditions. RSQ04 disrupted the cellular structure of L. monocytogenes and exhibited antibiofilm activity. This study systematically investigated the purification, characterization, safety assessment, and practical application of RSQ04, providing insights for the development and utilization of bacteriocins in the food industry.

Summary: A bacteriocin-producing strain, Brevibacillus laterosporus TK3, was isolated from 'Tatwakhar' flour made from Indian Horse Chestnut seeds. The strain was identified using morphological, biochemical techniques, and 16S rRNA gene sequencing. The bacteriocin showed strong antagonistic activity against food spoiling/pathogenic bacteria.

Summary: The anti-Listeria activity of four essential oils (EOs) and bacteriocin bacLP17 in coated shrimps was studied. The EOs showed inhibitory effects on L. monocytogenes in vitro and inside the coatings. A synergistic effect was observed when the EOs were used in combination, reducing the amount needed and improving the smell. The inclusion of EOs in the coatings increased the shelf-life and improved the sensory properties of the food.

Summary: The study showed that CFSconc obtained from Pediococcus spp. strains significantly inhibited the growth of applied L. monocytogenes strains during the storage period, while LAB culture broth and CFS could not reduce the growth of L. monocytogenes or B. thermosphacta. Concentrating preparations are important for obtaining a suitable antibacterial preparation that contributes to consumer safety and food quality when applied as a protective additive.

Summary: In this study, a novel two-component bacteriocin called acidicin P was discovered and characterized from Pediococcus acidilactici LAC5-17, showing obvious antimicrobial activity against L. monocytogenes. Key residues in both peptides of acidicin P were identified and found to play crucial roles in its antilisterial activity. Furthermore, acidicin P was found to induce permeabilization and depolarization of the cytoplasmic membrane, causing significant changes in the morphology and ultrastructure of L. monocytogenes cells. This research provides strong evidence for further development of acidicin P as an antilisterial drug.

Summary: Listeria monocytogenes is a significant concern in the food industry and bacteriocins from LAB are an attractive approach for food preservation and probiotics. This study used genetic sequencing and screening to identify bacterial isolates with antimicrobial activity, identifying heat-stable proteins/peptides as the active compounds in Pediococcus acidilactici and Lactococcus garvieae. The research provides a pipeline for high-throughput screening of potential starter cultures and probiotics producing antimicrobial compounds.

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.
