Unexpected Effects of Lantibiotic Preservatives on Gut Microbiome

A study from the University of Chicago reveals that lantibiotics, a class of bacteriocins used as food preservatives, have potent effects on both pathogens and commensal gut bacteria. The research found that these lantibiotics, including the popular nisin, can kill both harmful and beneficial gut bacteria, potentially disrupting the delicate balance of the gut microbiome. The study highlights the need to better understand the impact of lantibiotics on gut health and to harness their antimicrobial properties for beneficial use.
