does not use as carbon source

METPO:2000031 · OBJECT_PROPERTY · REVIEWED

An OBJECT_PROPERTY asserting that an organism does *not* use a given chemical entity as a source of carbon for biosynthesis. The intended use is predicate + class composition at assertion time, e.g. `<organism> METPO:2000031 CHEBI:17234` ("organism does not use glucose as carbon source"). Negation companion to METPO:2000006.

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.
