Report verdict: Recommended interpretation: a named marine algal culture-medium formulation (and, operationally, a formulation family), not a single chemical, salt, hydrate, buffer, or chemically uniform mixture. A modern methods paper assigns Dunaliella salina specifically to “2X Erdschreiber’s medium,” while assigning other algae to separately named media; this supports treating Erdschreiber’s as a me 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.
