DATABASE_MATCH
via CultureBotHT
Imported from CultureBotHT. CAS-RN 16788-57-1 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). Used in 6 CultureBot media; samples: MME noCarbon, MTM noNitrogen noCarbon, MME noNitrogen noCarbon…. Curator can promote to a CHEBI primary if/when CHEBI adds the term.
