Positive catalse test - Staphylococcus aureus In order to survive, organisms must rely on defense mechanisms that allow them to repair or escape the oxidative damage of hydrogen peroxide (H202). Some bacteria produce the enzyme catalase, which facilitates cellular detoxification. Catalase neutralizes the bactericidal effects of hydrogen peroxide and its concentration in bacteria has been correlated with pathogenicity. The catalase test facilitates the detection of this enzyme in bacteria. It is

Catalase test | This test is used to identify organisms that produce the enzyme, catalase. 🔸This enzyme detoxifies hydrogen peroxide by breaking it down into water and oxygen gas. The bubbles resulting from production of oxygen gas clearly indicate a catalase positive result. 🔸It is used to distinguish between Staphylococcus and Streptococcus bacteria. | Elmicrobiologist

The catalase test tests for the presence of catalase, an enzyme that breaks down the harmful substance hydrogen peroxide into water and oxygen. If an organism can produce catalase, it will produce bubbles of oxygen when hydrogen peroxide is added to it Purpose of Catalase Test The morphologically similar Enterococcusor Streptococcus (catalase negative) and Staphylococcus (catalase positive) can be differentiated using the catalase test. Also valuable in differentiating aerobic and obligate anaer
