  snippet: the acetoclastic methanogens split acetate to CH4 and CO2
  notes: Szuhaj et al. distinguish acetoclastic methanogens by their acetate-to-methane-and-carbon-dioxide
    branch of methanogenesis.

  snippet: acetoclastic methanogenesis using acetate
  notes: Evans et al. describe acetoclastic methanogenesis as the acetate-using branch
    among major methanogenic carbon-source pathways.

  prompt: Resolve an exact external ontology xref for acetate-splitting methanogenesis
    before adding a TraitRecord xref.
  kind: CURATION_TODO
  status: OPEN
  rationale: The pinned METPO snapshot contains only obsolete METPO:1000865 Acetoclastic
    methanogenesis. GO:0015948 methane biosynthetic process is exact only for the
    broader methanogenesis parent, and no exact active external class has yet been
    resolved for the acetate-splitting branch.

  changes: Minted acetoclastic methanogenesis as a DOI-backed child of methanogenesis
    after a repository-wide duplicate review covering ignored and hidden files; the
    pinned METPO snapshot has only an obsolete Acetoclastic methanogenesis class.
