“…This demonstrates the increased effectiveness of the marine-derived nisin Z under native conditions. More recently, Li et al [54] isolated a novel class IId bacteriocin, CAMT6 from the marine fish isolate Enterococcus durans YQ-6. CFS from this strain possessed a broad spectrum of activity, targeting both gram-positive and gram-negative bacteria, and also inhibited fungi.…”

The marine environment is the largest ecological habitat on Earth, albeit one of the least explored, particularly in terms of its microbial inhabitants. The marine fish gut is host to a diverse microbial community from which diverse bioactive molecules can be sourced. Due to the unique environmental pressures these microbial communities experience, the bioactive molecules they produce often evolve unique adaptations that give them diverse structures and activities, differentiating them from terrestrial homologues. Of particular interest, due to their structural and functional diversity, are the ribosomally-synthesized antimicrobial peptides (bacteriocins). With increasing pressure from emerging antibiotic-resistant disease and industrial demand for novel therapeutics, the marine fish gut microbiome represents a relatively untapped resource of novel bacteriocins that could prove beneficial to human health and aquaculture. This review presents an overview of the marine fish gut microbiome and explores its potential as a source of bacteriocins for human health with considerations for applications and future research in this area.

“…Studies have shown that nisin affects the production of reactive oxygen species in cells of Bacillus subtilis ( B. subtilis ) and S. aureus through the mitochondrial electron transport chain [ 55 ]. A novel bacteriocin CAMT6 produced by Enterococcus durans YQ-6 isolated significantly removed biofilms produced by L. monocytogenes ATCC 19111 and inhibited L. monocytogenes by disrupting the permeability of the cell membrane ( p < 0.05) [ 41 ]. In addition to their antimicrobial effects, certain bacteriocins show other biological activities, such as anti-inflammation, anti-oxidation, regulating intestinal flora, and improving colitis [ 56 , 57 , 58 ].…”

In recent years, food safety caused by foodborne pathogens and spoilage bacteria has become a major public health problem worldwide. Bacteriocins are a kind of antibacterial peptide synthesized by microbial ribosomes, and are widely used as food preservatives. However, when used individually bacteriocins may have limitations such as high cost of isolation and purification, narrow inhibitory spectrum, easy degradation by enzymes, and vulnerability to complex food environments. Numerous studies have demonstrated that co-treatment with bacteriocins and a variety of chemical substances can have synergistic antibacterial effects on spoilage microorganisms and foodborne pathogens, effectively prolonging the shelf life of food and ensuring food safety. Therefore, this paper systematically summarizes the synergistic bacteriostatic strategies of bacteriocins in combination with chemical substances such as essential oils, plant extracts, and organic acids. The impacts of bacteriocins when used individually and in combination with other chemical substances on different food substrates are clarified, and bacteriocin–chemical substance compositions that enhance antibacterial effectiveness and reduce the potential negative effects of chemical preservatives are highlighted and discussed. Combined treatments involving bacteriocins and different kinds of chemical substances are expected to be a promising new antibacterial method and to become widely used in both the food industry and biological medicine.
