definition: An anaerobic respiration in which an organism uses iodate as the terminal
  electron acceptor for energy conservation.

  snippet: SCT was capable of anaerobic growth with 3 mM iodate as the sole electron
    acceptor
  notes: Amachi et al. isolated Pseudomonas sp. strain SCT from marine sediment slurry
    and showed anaerobic growth with iodate as sole electron acceptor.
- reference: DOI:10.1128/AEM.00241-07
  snippet: SCT is a dissimilatory iodate-reducing bacterium
  notes: Amachi et al. support the dissimilatory iodate reduction synonym and organism-level
    phenotype scope.
- reference: DOI:10.1038/s41396-021-01034-5
  snippet: dissimilatory IO3− reduction to iodide (I−) by a novel estuarine bacterium,
    Denitromonas sp. IR-12
  notes: Reyes-Umana et al. show that iodate respiration recurs in an estuarine Denitromonas
    isolate.
- reference: DOI:10.3389/fmicb.2021.804181
  snippet: A. toluclasticum sp. TC-10 couples acetate oxidation to iodate reduction
    with a concomitant increase in the OD600.
  notes: Reyes-Umana et al. extend the dissimilatory iodate-reducing phenotype to
    the freshwater isolate Aromatoleum toluclasticum sp. TC-10.

discussions:
- discussion_id: iodate-respiration-xref-gap
  prompt: Resolve an exact external ontology class for organism-level iodate respiration
    before adding a TraitRecord xref.
  kind: CURATION_TODO
  status: OPEN
  rationale: Candidate Idr, DmsAB, EC, Rhea, and protein-family terms describe narrower
    iodate reductase activities, reactions, or enzymes rather than the whole-organism
    anaerobic respiration phenotype.

  changes: Minted iodate respiration as a DOI-backed anaerobic respiration TraitRecord
    after a repository-wide duplicate review covering ignored and hidden files; the
    local METPO snapshot has no exact iodate respiration class and the replacement
    placeholder is reserved in proposals/metpo_traitmech_v80.
