identifier: METPO:1007081
label: oxidase test
definition: A biochemical test that detects cytochrome c oxidase activity using a
  redox indicator. The test outcome (positive or negative) is captured by its child
  classes; this class itself does not assert oxidase activity.

  snippet: The oxidase test is a biochemical reaction that assays for the presence
    of cytochrome oxidase
  notes: The American Society for Microbiology oxidase-test protocol describes the
    assay as a biochemical reaction that reads cytochrome oxidase.

  snippet: The ability of bacteria to produce the enzyme cytochrome oxidase can be
    determined by performing an oxidase test
  notes: Hafezi and Khamar review oxidase-test use for determining bacterial cytochrome
    oxidase production.
