Characterization of the Structural Gene Encoding Nisin F, a New Lantibiotic Produced by a <i>Lactococcus lactis</i> subsp. <i>lactis</i> Isolate from Freshwater Catfish ( <i>Clarias gariepinus</i> )

Abstract

Lactococcus lactis F10, isolated from freshwater catfish, produces a bacteriocin (BacF) active against Staphylococcus aureus, Staphylococcus carnosus, Lactobacillus curvatus, Lactobacillus plantarum, and Lactobacillus reuteri. The operon encoding BacF is located on a plasmid. Sequencing of the structural gene revealed no homology to other nisin genes. Nisin F is described.
