METPO:1005010 · CLASS · SEEDED

An assay that tests the ability of an organism to produce indole from tryptophan.

Trait evidence (2)

  • https://asm.org/protocols/indole-test-protocol
    The indole test screens for the ability of an organism to degrade the amino acid tryptophan and produce indole.

    The ASM protocol defines the indole test as an assay for organism-level tryptophan degradation to indole.

  • https://asm.org/protocols/indole-test-protocol
    The chief requirement for culturing an organism prior to performing the indole test is that the medium contains a sufficient quantity of tryptophan (5).

    The protocol explains that the indole-test medium needs tryptophan so production of indole can report tryptophan degradation.

  2. · ENRICHED_FROM_LITERATURE · codex

    Added the METPO indole-test assay parent with stable-URL tryptophan-to-indole assay evidence after a repository-wide duplicate review covering ignored and hidden files.

  3. · CURATION_REVIEW_REVISION · codex

    Preserved the ASM source-local tryptophan citation marker after Claude Code Review issue #874 so the second evidence snippet is visibly a complete sentence.
