How are catalase tests used to identify Enterobacteriaceae?
Catalase test can be used as an aid to the identification of Enterobacteriaceae. Pour 1-2 ml of hydrogen peroxide solution into a test tube. Using a sterile wooden stick or a glass rod, take several colonies of the 18 to 24 hours test organism and immerse in the hydrogen peroxide solution. Observe for immediate bubbling.
What is the purpose of the catalase enzyme?
Catalase is an enzyme, which is produced by microorganisms that live in oxygenated environments to neutralize toxic forms of oxygen metabolites; H 2 O 2. The catalase enzyme neutralizes the bactericidal effects of hydrogen peroxide and protects them.
