The catalase test tests for the presence of catalase, an enzyme that breaks down the harmful substance hydrogen peroxide into water and oxygen.
Dispose of the slide in a slide disposal bin and any toothpicks in a biohazard bin.
Abstract The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor.
The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen, where a higher concentration of inhibitor will yield less oxygen, resultant of a lower rate of reaction.
Add one drop of hydrogen peroxide and look for bubbles.
Bubbles are a positive result for the presence of catalase.
