- Reference text
- Levy et al. (2016). Chlorobaculum tepidum modulates amino acid composition in response to energy availability.
- Curator note
- The paper tests thiosulfate-fed cultures. Applying this role to dissolved sodium thiosulfate pentahydrate is a chemical inference about the supplied anion; the study does not establish a hydrate-specific growth comparison.
- Metabolic context
- Dissolved thiosulfate donor for Chlorobaculum tepidum WT2321 under the studied illuminated, anoxic culture conditions.

| 2026-08-20T00:00:00+00:00 | merge_identifier_collisions | MERGED_FROM | Absorbed 'Sodium Thiosulfate Pentahydrate' (#414). Both records held CHEBI:32150 while both were live, which MIM's own rule forbids — for a mapped record the identifier IS the ontology CURIE, so two live records on it assert that two ingredients are one thing. They are one thing: formula notation versus spelled-out name of the same pentahydrate; identical CAS 10102-17-7, and both state the hydration explicitly so neither can be the anhydrous form. 'Na2S2O3 x 5 H2O' wins as the label media actually use (455 occurrences against 3); the other survives as a RAW_TEXT synonym, so label_index still answers for it. | |
