Bacteriocin-producing strains and purified bacteriocins can
be applied to food, animals, and medicine. If bacteriocin-producing
strains are applied through start culture or co-culture in food, it can extend
the preservation of food. Probiotics produced by bacteriocins can balance
the bacteria in the digestive tract to reduce gastrointestinal diseases.
Purified bacteriocins can be added directly to foods as a natural
preservative. Bacteriocins can be added to animal feed as an anti-pathogen
additive to protect livestock against pathogen damage. The bacteriocins
used in medicine can improve the quality of human life. Bacteriocins have
the potential to replace antibiotics as an antibacterial drug, and are a novel
anti-cancer drug.
