Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

  1. CONFIRM_UNGROUNDED 2026-08-21 · codex-gpt-5

    Confirmed UNGROUNDED: no ontology term fits this concept. Non-habitat screen review (#108): Engineered > Industrial production > Chemical products > Buffer denotes a manufactured buffer solution or product, a physical fluid material in which microbes can occur. An external chemical term identifies the chemical role but is not in the committed slice. (source concept habitatmech:GOLD.f037760cf2)

  2. DEFINED 2026-09-18 · codex-gpt-5

    Defined as 'buffer solution' under ENVO:2000000 'chemical product'. Definition authored from the existing item-level #108 decision, GOLD's Engineered > Industrial production > Chemical products > Buffer source path, the local ENVO chemical-product hierarchy, CHEBI:35225 'buffer', Good et al. 1966 (DOI:10.1021/bi00866a011), and Houlsby et al. 1988 (PMID:3280650). GOLD's source denotes a manufactured pH-buffering solution or product in which microbes can occur rather than a natural buffered system, a blank-control role, pure lab-grade water or sheath fluid sibling, ENVO:00000135 'buffer zone', a formulation-specific PBS/Tris/HEPES solution, or CHEBI:35225 as a pH-resistance chemical role rather than a material habitat. ENVO:2000000 'chemical product' is the tightest vendored genus and the existing source-inherited parent, so parent_mode=ADD preserves the GOLD Chemical products hierarchy.
