|
0.6955 MILLIMOLAR |
CHEBI:32312
zinc sulfate heptahydrate
|
Primary recipe input: 0.2 g ZnSO4.7H2O per 1 L distilled water. Final solution volume is not explicit. The stored molarity is retained as a database assertion, not independently verified final-medium concentration; no conversion was applied. |
| 11 | copper(II) chloride dihydrate | 0.02933 MILLIMOLAR | Primary recipe input: 5 mg CuCl2.2H2O per 1 L distilled water. Final solution volume is not explicit. The stored molarity is retained as a database assertion, not independently verified final-medium concentration; no conversion was applied. No exact supplied-hydrate identifier is assigned: the packaged candidate's public ChEBI page was unavailable. The prior non-hydrate grounding is withdrawn, not a new identifier inferred. | |
| 12 | Ammonium heptamolybdate tetrahydrate | 0.004045 MILLIMOLAR | Primary recipe input: 5 mg (NH4)6Mo7O24.4H2O per 1 L distilled water. Final solution volume is not explicit. The stored molarity is retained as a database assertion, not independently verified final-medium concentration; no conversion was applied. CHEBI:91249 identifies orthomolybdate, not the source heptamolybdate tetrahydrate. The conflicting mapping is withdrawn; no replacement is assigned and the MIM snapshot is unchanged. | |
| 13 | Sodium glutamate monohydrate | 12.5 G_PER_L | The source's initial 12.5 g/L input replaces MediaDB 66.8 mM; this is source-unit restoration, not a claim that the database conversion was numerically wrong. No exact supplied-hydrate identifier is assigned: the packaged candidate's public ChEBI page was unavailable. The prior non-hydrate grounding is withdrawn, not a new identifier inferred. |
Preparation
- Dissolve all ingredients in distilled water to specified concentrations
- Adjust pH if specified in original formulation
- Sterilize by filtration (0.22 μm) to preserve heat-sensitive components

| 2026-10-10T05:02:53.552216+00:00 | codex | CURATED_HAJJAJ_SOURCED_INGREDIENT_AMOUNTS_AND_FORMS | The 180 retained mineral molarities in article-linked records remain upstream database assertions; water-input basis is not assumed to be final solution volume. The two unlinked sibling records retain all 26 database molarities. Their primary-paper association and remaining chemical forms are unresolved, not borrowed from the linked family. Copper and sodium-glutamate hydrate identifiers remain unassigned after withdrawal of unverified non-hydrate grounding. Isoleucine stereochemistry is unspecified, not inferred. Heptamolybdate has no replacement identifier; the conflicting packaged MIM synonym is not used and the immutable index is unchanged. The source's Table 2 glutamic-acid equivalents are not the weighed sodium-glutamate hydrate; record 318 retains the batch-text/Figure 3 glucose discrepancy in evidence. Paper and ontology verification is manual; no raw primary-article capture or successful automated DOI full-text verification is asserted. Existing preparation, classification, application and organism/role claims are preserved and not certified by this ingredient curation. No IDs, category paths, growth claims or taxa-media associations are added. |
