the catalase test is an important, and rapid-acting, test for differentiating
The inadvertent use of a mixed culture in. biochemical testing will lead to erroneous results. The simplest biochemical test that is used to differentiate between Streptococcus and. Staphylococcus species is the Catalase test. In this test we are testing for the ability of the. bacteria to produce the enzyme catalase. This enzyme breaks down hydrogen peroxide into. water and oxygen. Hydrogen peroxide, as well as superoxides, can be metabolic end. products of the production of ATP by the electron transport chain.
