Gelatin Hydrolyzed

Ontology mapping

Primary identifier: UNMAPPED_0731
Notes: Imported from microbedecoder (source_id=kgmicrobe.trait:gelatin_hydrolyzed); no CAS-RN or CHEBI/NCIT match. Curator review needed. Retired as an ingredient record (#213/#308): names the gelatinase TEST result, not a substance. MicrO models it as MICRO:0000649 'gelatinase assay'. Hydrolysed gelatin does exist as a commercial product, but neither ChEBI nor FOODON has a term distinguishing it from gelatin, and a phenotype table reports the reaction. The substrate is already a record: `Gelatine` (CHEBI:5291). Not mapped, because every substrate CURIE it could be grounded to is already the primary key of a live record — in MIM the identifier IS the ontology CURIE, so a mapping here would mint a duplicate rather than add coverage. No synonym is folded onto those records either: this label names a reaction or a splice, not the substance, and asserting the synonymy would make label_index resolve it to something it does not denote.

2026-08-04T02:54:09.684805+00:00	audit_import_ingredients[microbedecoder]	CREATED_AS_UNMAPPED	UNMAPPED	Imported from microbedecoder (source_id=kgmicrobe.trait:gelatin_hydrolyzed); no CAS-RN or CHEBI/NCIT match. Curator review needed.
2026-08-06T00:00:00+00:00	issue_213_residual_triage LLM	FLAGGED_NEEDS_EXPERT	NEEDS_EXPERT	Not an ingredient as written: the hydrolysed state of gelatin is an assay READOUT (gelatinase activity), not a distinct substance added to a medium. Same scope question as #209. Searched CHEBI, NCIT, FOODON, ENVO, MeSH, BTO and UBERON by label and synonym with normalisation, plus exact queries across all of live OLS4.
2026-08-06T00:00:00+00:00	edison_literature_identity LLM	ANNOTATED		Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Gelatin_Hydrolyzed-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: ## Executive recommendation — Retain `UNMAPPED` in MediaIngredientMech and classify the record as a likely non-ingredient/phenotype import. The strongest interpretation of `kgmicrobe.trait:gelatin_hydrolyzed` is “gelatin hydrolysis positive”—a microbial biochemical phenotype indicating gelatinase/protease activity—not a material added to culture medium. In standard testing, the starting su No ontology CURIE was proposed. Recorded as provenance only — no grounding applied from this run. Edison's recommendations are deliberately conservative, and a plausible identifier promoted by a mechanism that never decided anything is what #203 and #263 exist to undo. Any CURIE above is a curator's to accept or reject.
