The original fetcher read fixed column positions, so the row ordinal was stored as the ingredient name, the component name as the amount, and the Amount column was never read; concentration was then filled in as G_PER_L regardless.

2026-10-10T03:53:28.828041+00:00 codex CURATED_UTEX_BRISTOL_BBM_INGREDIENT_AND_PREPARATION_EVIDENCE The BBM trace source prints MnCl with tetrahydrate; its intended chemical identity and the existing MnCl2 amount remain unverified. Added node evidence supports only that source-spelling conflict. BBM trace concentration columns and stock-page parenthetical micromolar values conflict with explicit stock preparation amounts. Preserve inspected Amount-per-litre stock recipes, not those incompatible columns; no new final-medium conversions. The BBM iron stock does not specify acid strength. No density, purity or molarity is assumed. The BBM study cites Stein 1973; exact equivalence with the current UTEX parent is unverified. NH4Cl ppm basis and culture working volume remain unspecified; no numerical conversion or aliquot inference. Bristol-NaCl uses an unfinished parent preparation; its table one-litre row is not certified as a working dose of completed Bristol. The reference and explicit stage notes are retained without a fabricated dose. Optional agar formulations are not silently added to these liquid records. No new taxa-media associations, IDs or growth/role assertions are curated. Supplier-catalog identities, generic incubation/light claims and unrelated preexisting organism evidence are not blanket-certified by this ingredient review.
