MANUAL_CURATION
via MIM curation (#260)
Created to cover a CultureMech label MIM could not resolve (#260): the phenazine pH-indicator dye used in MacConkey-type and clostridial media. ChEBI names it exactly and no MIM record holds the term. CHEBI:86372 'neutral red base' and CHEBI:86373 'neutral red(1+)' are the free base and cation; media recipes weigh out the dye itself.
