What is Nisin Q?
Nisin Q is a real nisin-family bacteriocin produced by Lactococcus lactis subsp. cremoris. It is studied as a potent Gram-positive inhibitor with food and gut-health potential because it preserves the core nisin mode of action while showing distinct variant properties.

Nisin Z
Nisin Z, a natural Lactococcus lactis lantibiotic variant
Nisin Z is a food-grade lantibiotic closely related to nisin A but with slightly different physicochemical behavior. It targets Gram-positive bacteria by binding lipid II and forming membrane pores, making it relevant to probiotic and gut-microbiome applications.
Probiotic PeptidesNisin F
Nisin F, a Lactococcus lactis-derived natural nisin variant
Nisin F is a naturally occurring nisin variant identified from Lactococcus lactis strains associated with fermented and human-associated niches. Like other nisin-family peptides, it acts mainly on Gram-positive bacteria through lipid II targeting and membrane disruption.
Probiotic PeptidesNisin U
Nisin U, a Streptococcus uberis lantibiotic
Nisin U is a bona fide nisin variant isolated from Streptococcus uberis and is notable as a non-Lactococcus nisin-family peptide. It is active against Gram-positive organisms and is of interest for microbiome and probiotic-adjacent antibacterial strategies.
Probiotic PeptidesNisin O
Nisin O, a gut-derived Blautia-associated nisin-family peptide
Nisin O is a gut microbiome-associated nisin-like peptide reported from a Blautia-related anaerobic isolate. Its discovery is important because it links the nisin scaffold directly to intestinal microbial ecology and probiotic-style peptide discovery.
