A NOVEL BACTERIOCIN FROM A NEW STREPTOMYCES SPECIES

摘要

Provided is an isolated novel Gram-positive non-motile, non-spore-forming, aerobic bacterium designated Streptomyces scopuloiridis, wherein the bacterium produces a bacteriocin that kills or inhibits the growth of Gram-positive or Gram-negative target bacteria. Also provided are novel purified polypeptides, and fragments thereof, and isolated nucleic acids from the bacterium. Further provided are methods of using the bacterium and the purified polypeptides, and fragments thereof, to preserve food and prevent bacterial contamination of food.
