What is "bisin"

Bisin is a naturally occurring lantibiotic (an antibacterial peptide) discovered by University of Minnesota microbiologist Dan O'Sullivan. Unlike earlier lantibiotics discovered, such as nisin, bisin also kills Gram-negative bacteria, including E. coli, Salmonella and Listeria.

The food-preservative properties of bisin could lead to food products that resist spoilage for years.
