  snippet: Bacteriocins are ribosomally synthesized antimicrobial peptides produced
    by bacteria, which have the ability to kill or inhibit other bacteria.
  notes: Rea et al. review bacteriocins as bacterially produced ribosomal antimicrobial
    peptides.
- reference: DOI:10.1146/annurev.micro.56.012302.161024
  snippet: 'the most abundant and diverse family of microbial defense systems: the
    bacteriocins.'
  notes: Riley and Wertz support bacteriocins as a widespread, diverse microbial defense-system
    family.

  snippet: Traditionally, nisin was produced industrially by using Lactococcus lactis
    in the neutral fermentation process.
  notes: Zhang et al. support Lactococcus lactis as an industrial nisin-producing
    bacterium.

  note: Lactococcus lactis is used as a canonical nisin-producing bacterium in neutral
    fermentation.

  changes: Minted bacteriocin production as a DOI-backed TraitRecord after a repository-wide
    duplicate review covering ignored and hidden files; METPO has no exact bacteriocin
    production class yet and the placeholder is reserved in proposals/metpo_traitmech_v60.
