Catalase test

What is the reagent used in this test?


Expert Answer

Step 1

It is required to identify the reagents that are used in the Catalase test.

Step 2

Catalase is an enzyme found in the living organisms which are exposed to oxygen like plants, animals, microorganisms and humans. This enzyme catalyzes the decomposition of hydrogen peroxide into oxygen and water.  The catalase test demonstrates the presence of catalase enzyme and is used to differentiate between the bacteria which produce catalase enzyme like staphylococci and the bacteria which lack the production of this enzyme like streptococci.

Step 3

Most of the organisms which contain cytochrome produce the enzyme catalase. When a small amount of any catalase producing organism is introdu...
