    Abstract The gut microbes interact with each other as well as host, influencing human health and some diseases. Many gut commensals and food originated bacteria produce bacteriocins which can inhibit pathogens and modulate gut microbiota. Bacteriocins have comparable narrow antimicrobial spectrum and are attractive potentials for precision therapy of gut disorders. In this review, the bacteriocins from food and gut microbiomes and their involvement in the interaction between producers and gut ecosystem, along with their characteristics, types, biosynthesis, and functions are described and discussed. Bacteriocins are produced by many intestinal commensals and food microbes among which lactic acid bacteria (many are probiotics) has been paid more attention. Bacteriocin production has been generally regarded as a probiotic trait. They give a competitive advantage to bacteria, enabling their colonization in human gut, and mediating the interaction between the producers and host ecosystem. They fight against unwanted bacteria and pathogens without significant impact on the composition of commensal microbiota. Bacteriocins assist the producers to survive and colonize in the gut microbial populations. There is a great need to evaluate and utilize the potential of bacteriocins for improved therapeutic implications for intestinal health.

    Abstract Nisin Z is a possible alternative for treating bovine mastitis by inhibiting mastitis-causing pathogens and having anti-inflammatory activity. However, the anti-inflammatory mechanism of nisin Z on mastitis is unknown. Our study aimed to investigate the mechanisms of nisin Z on mastitis. Our results showed that nisin Z inhibited the activation of the ERK1/2 and p38 mitogen-activated protein kinase (MAPK) signaling pathway, decreased the release of pro-inflammatory cytokines (i.e., tumor necrosis factor-α, IL-1β, and IL-6), and increased the anti-inflammatory cytokine (IL-10) in lipopolysaccharide (LPS)-induced MCF10A cells. After intraperitoneal injection, nisin Z significantly decreased inflammatory cell infiltration in the mammary gland, as well as decreased myeloperoxidase and pro-inflammatory cytokines in serum and mammary gland. Western blot analysis revealed that nisin Z also dramatically suppressed the activation of the ERK1/2 and p38 MAPK signaling pathways in LPS-induced mastitis mice. We also found that nisin Z treatment could enhance the blood-milk barrier. In summary, our study demonstrated that nisin Z exerted an anti-inflammatory effect by inhibiting the ERK1/2 and p38 MAPK signaling pathway and promoting the blood-milk barrier on LPS-induced mastitis.

    Abstract Lanthipeptides are known antimicrobial agents having great potential for application in food preservation. Many lanthipeptide biosynthetic gene clusters (BGCs) were mined in fermented food microbiota, however, it is difficult to obtain the bioactive lanthipeptides and their producing strains. Here, we established a high-throughput strategy designated Metagenomic Mining of Isolates Population (MMIP) to efficiently excavate and obtain novel lanthipeptides, especially their potential producing strains. MMIP procedure involves gathering bacteria isolates using culturable strategy, metagenomic mining for lanthipeptides and screening their producers, and characterization of specific lanthipeptides. 928 biosynthetic gene clusters including 139 ribosomally synthesized and post-translationally modified peptides (RiPPs) gene clusters were discovered in the metagenomic data of the isolates by antiSMASH. Entianin, lactocin S, lichenicidin, and 17 novel lanthipeptides gene clusters corresponding to 29 possible producers were further found from the harvested isolates population. Entianin and a novel two-component lanthipeptide paralicin were purified from Bacillus subtilis C5B1 and Bacillus paralicheniformis BaC1-8, respectively. They showed strong inhibitory activity to food spoilage bacteria Bacillus cereus and Listeria monocytogenes, and have great potential for application in food preservation. A novel lanthipeptide polysacin was also obtained using semi-in vitro biosynthesis. MMIP affords a novel strategy for effectively excavating lanthipeptides, especially their producers from diverse environmental niches.

    Abstract Listeria monocytogenes is an important pathogen which easily contaminates food and causes fatal systemic infections in human. Bacteriocins have received much attention regarding their natural methods of controlling health-related pathogens. Here, we investigated and characterized a novel two-component bacteriocin named acidicin P from Pediococcus acidilactici LAC5-17. Acidicin P showed obvious antimicrobial activity to L. monocytogenes. Through a sequence similarity network analysis for two-component bacteriocin precursors mined in the RefSeq database, acidicin P was observed to belong to an unusual group of two-component bacteriocins. Acidicin P contains two peptides designated Adpα and Adpβ which are assessed to interact with each other and form a helical dimer structure which can be inserted into the lipid bilayer of target cell membrane. We demonstrate that A5, N7, and G9 in the A
