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

  snippet: A gram-negative, strictly anaerobic, motile vibrio was isolated from a
    selenate-respiring enrichment culture
  notes: Oremland et al. isolated strain SES-3 from a selenate-respiring enrichment
    culture and showed anaerobic growth coupled to selenate reduction.
- reference: DOI:10.1128/AEM.02737-06
  snippet: use selenate as a terminal electron acceptor
  notes: Narasingarao and Haggblom define the phenotype as use of selenate as a terminal
    electron acceptor in dissimilatory selenate reduction.

  snippet: four novel anaerobic dissimilatory selenate-respiring bacteria
  notes: Narasingarao and Haggblom support selenate respiration as a repeatedly observed
    microbial trait across aquatic-sediment isolates rather than a single strain-specific
    anomaly.

  snippet: Here we characterize a novel selenate-respiring bacterium, strain AK4OH1,
    isolated from an estuarine sediment enrichment culture
  notes: Narasingarao and Haggblom described Sedimenticola selenatireducens AK4OH1
    as an anaerobic selenate-respiring bacterium isolated from estuarine sediment.

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

  changes: Minted selenate 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 selenate respiration class and the replacement
    placeholder is reserved in proposals/metpo_traitmech_v79.
