bacteriocin

noun bakˈtɪərɪə(ʊ)sɪnˌbakˈtirēəsən
Biology
  • A protein produced by bacteria of one strain and active against those of a closely related strain.

    • Partly it may be due to its production of the so-called enterocins, a family of bacteriocins, which are antimicrobial peptides produced by some bacterial strains.
    • They produce antibiotics known as bacteriocins that are poisonous to their own species.
    • For example, certain protein receptors are common to a colicin and a virulent phage; others, like the fig product, can adsorb a bacteriocin, virulent phages of distinct origins, and even a temperate phage.
