This paper identifies a novel nisin variant, nisin G, produced by a gut-derived Streptococcus salivarius strain with narrow activity against Fusobacterium nucleatum.

First evidence of production of the lantibiotic nisin P

The paper identifies a human fecal isolate producing nisin P, confirms its structure, and compares its antimicrobial activity to nisin A and H.
