DATABASE_MATCH
via MIM curation (#114)
P-IV Metal Solution is a named, recurring multi-component preparation (16 media). Searched CHEBI, NCIT, MeSH, FOODON and ENVO by label and synonym with normalisation: no term denotes it, and none could -- it is a lab preparation rather than a substance. Takes the STOCK_SOLUTION convention used by the existing mapped records: a kgmicrobe.ingredient: mint, with no parent because a multi-component mix does not narrow to any single compound (#114).
