MANUAL_CURATION via MIM curation (#213/#308)

Decomposed into 2 constituents: the label names two substances — esculin and ferric citrate, the latter an exact synonym of CHEBI:144421 iron(III) citrate. Minted under the #288 STOCK_SOLUTION convention because no ontology term denotes the blend itself. ingredient_type=DEFINED_MEDIUM. No concentrations recorded — the label states none.

SOURCE_LABEL microbedecoder — Esculin Ferric Citrate

The source label explicitly names every retained top-level part.

This is an ingredient/mixture has-part assertion, not an identity mapping, variant hierarchy, or complete culturing recipe.

2026-08-06T00:00:00+00:00 issue_213_residual_triage LLM FLAGGED_NEEDS_EXPERT NEEDS_EXPERT Not a single-compound grounding target: a two-component reagent (esculin CHEBI:4853 plus ferric ammonium citrate CHEBI:31604, both of which exist as their own MIM records) used in bile esculin agar. A narrowMatch would be wrong because a mixture is not narrower than one of its components; it needs decomposition. 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/Esculin_Ferric_Citrate-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** “Esculin Ferric Citrate” is a **multi-component diagnostic substrate–indicator reagent**, not a single covalently defined chemical, salt, hydrate, buffer, extract, or complete culture medium. In the API 20 NE context it is the active material for the **ESC (esculin) test**, which detects β-glucosidase-mediated esculin hydrolysis; positive reactions change from yello 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.

Decomposed into 2 constituents: the label names two substances — esculin and ferric citrate, the latter an exact synonym of CHEBI:144421 iron(III) citrate.

The record was already MAPPED; it had been promoted in place by a path that does not move between collections, and reconcile_sssom reads only the mapped collection — so its mapping was curated but unpublished.
