- Source: KOMODO ModelSEED | ID: 911 | DSMZ Medium: 911 (mediadive.medium:911) | Aerobic: No Superseded historical provenance (not a current formulation claim): Commercial Product: LB Medium (Luria-Bertani, Miller formulation) Supplier: Multiple suppliers (Difco, Sigma, etc.) Catalog: Multiple (L3522 Sigma, 244520 BD) Source: https://www.laboratorynotes.com/preparation-of-luria-bertani-lb-miller-broth/ Accessed: 2026-03-28 Constituent composition researched from product specification. This record now follows its own KOMODO table rather than the composition copied from DSMZ. Rates remain provider-qualified; a dilution mechanism is unresolved. Null PH Info is not replaced by a copied pH assertion. No source omission proves an experimentally absent ingredient. Source-specific ingredient identities, quantity bases and preparation routes supersede the copied flattened amounts. Historical events are preserved. Chemical groundings are not comprehensively recertified; no taxa-media association is added.
