MANUAL_CURATION
via MIM curation (#213/#308)
Grounded to the ChEBI class CHEBI:78037 ('polyhydroxyalkanoate'): poly-beta-hydroxyalkanoate and polyhydroxyalkanoate are the same polymer class under two spellings — the beta- records the 3-hydroxy position that PHA implies — so this is a naming variant, not a subclass relation, and needs no registry mint.

MeSH:D054813 'Polyhydroxyalkanoates' is the closest term but does not carry this label as a synonym, and the 'beta' is a specificity the class term drops. Needs a granularity decision. Searched CHEBI, NCIT, FOODON, ENVO, MeSH, BTO and UBERON by label and synonym with normalisation, plus exact queries across all of live OLS4. |

Report verdict: **Recommended interpretation:** a legacy name for the **polyhydroxyalkanoate (PHA) polymer family**, not a single chemical, salt, hydrate, buffer, extract, commercial formulation, or defined culture-medium mixture. PHAs are microbial polyesters containing hydroxyalkanoate repeat units and encompass chemically distinct homopolymers, random or block copolymers, and terpolymers. Their monomer composi 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. | |

Grounded to the ChEBI class CHEBI:78037 ('polyhydroxyalkanoate'): poly-beta-hydroxyalkanoate and polyhydroxyalkanoate are the same polymer class under two spellings — the beta- records the 3-hydroxy position that PHA implies — so this is a naming variant, not a subclass relation, and needs no registry mint. |

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not move between collections, and reconcile_sssom reads only the mapped collection — so its mapping was curated but unpublished. | |

Tokens already present on the kg-microbe ontology node were left out as redundant (#520). |
