identifier: METPO:1007080
label: catalase test
definition: A biochemical test that detects catalase enzyme activity by exposing cells
  to hydrogen peroxide and observing for visible bubbling. The test outcome (positive
  or negative) is captured by its child classes; this class itself does not assert
  that the organism has catalase activity.

  snippet: The catalase test facilitates the detection of this enzyme in bacteria
  notes: The American Society for Microbiology catalase-test protocol describes the
    bacterial assay context for detecting catalase.

  snippet: The enzyme-generated oxygen bubbles trapped by Triton X-100 were visualized
    as foam
  notes: Iwase et al. support the visible oxygen-bubble readout produced by catalase-mediated
    hydrogen-peroxide decomposition.
