Notes
Source: KOMODO ModelSEED | ID: 829 | DSMZ Medium: 829 (mediadive.medium:829) | Aerobic: Yes Superseded historical provenance, not a current formulation claim: Commercial Product: LB Medium (Luria-Bertani, Miller formulation) Supplier: Multiple suppliers (Difco,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. Preserve the provider's aerobic metadata as a source assertion, not a biological growth claim. Its linked original specifies anoxic preparation; any disagreement remains unresolved rather than silently overriding either source. The original's anoxic instructions and stock preparations are separate source context; they do not override the provider's exact reported table rates and nulls. This source reports sodium bicarbonate, whereas original DSMZ829 lists sodium carbonate. Preserve exact source chemical identity; do not rename or average the two formulations. Original DSMZ829 lists 0.50 g sodium carbonate per basal batch; this is source comparison, not permission to replace the provider's bicarbonate rate. The provider's displayed dithionite rate remains distinct from the original's 1 ml addition of 5% w/v stock; do not replace a source-specific rate with a different formulation's dilution. Original DSMZ829's dithionite stock strength and receiving input are separate from the KOMODO rate; the formulations are not certified identical. Remove KOMODO829a from this source-duplicate group: its exact table is a distinct salt/thiosulfate formulation explicitly linked to DSMZ829a, not a copy of the sea-salt/growth-factor base. Preserve the new reciprocal DSMZ829a source-derivation link. Full exact-source recipe and stock/preparation tables were inspected. Reconstructed nodes retain explicit source scope; complete prior ingredient/stock assertions, including copied LB mappings and stage conflations, are archived in append-only history. A title alone is not the basis for removal. Unchanged annotations are preserved, not recertified; no new organism-growth association is added.
