  Curator note
  Mc_trace_minerals_SO4free is a 1000X stock of citrate-chelated chloride, borate, molybdate, selenate, vanadium, and tungstate trace salts for Mc media; the source lists no sulfate salts, preserving the sulfate-free intent of the formulation.

DATABASE_MATCH via MIM curation (#114)

Mc_trace_minerals_SO4free is a named, recurring multi-component preparation (22 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).
