Apidaecin vs Nisin

Apidaecin vs Nisin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Apidaecin
Antimicrobial Peptide

Apidaecins are proline-rich antimicrobial peptides from the hemolymph of honeybees (Apis mellifera). Unlike membrane-disrupting AMPs, apidaecins kill bacteria exclusively through intracellular ribosome targeting after transporter-mediated uptake, similar to Bac7 and PR-39....

Nisin
Antimicrobial Peptide

Nisin A is a 34-residue lanthipeptide bacteriocin produced by Lactococcus lactis. It is the only bacteriocin approved for food use by the FDA (GRAS status, E234 in EU), widely used as a natural food preservative in dairy, canned goods, and processed meats....
