does not use as electron acceptor

METPO:2000034 · OBJECT_PROPERTY · REVIEWED

An OBJECT_PROPERTY asserting that an organism does *not* use a given chemical entity as a terminal electron acceptor in respiration. The intended use is predicate + class composition at assertion time, e.g. `<organism> METPO:X CHEBI:17632` ("organism does not use nitrate as electron acceptor"). Negation companion to METPO:2000008.

Deprecated generic chemical-use relation carrier; later replacement should use more specific trait records that combine the relation with the chemical, metabolic role, growth condition, and positive or negative usage context.

Restored from DEPRECATED to REVIEWED under the predicate+class composition pattern (intended use: <organism> + this predicate + CHEBI chemical class). Added DOI/PMID-backed definition, evidence, and explicit domain/range slots.
