The catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative). The enzyme, catalase, is produced by bacteria that respire using oxygen, and protects them from the toxic by-products of oxygen metabolism.he catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative).

Catalase is an enzyme that promotes the decomposition of hydrogen peroxide to water and oxygen gas: H2O2 ï  H2O + O2. Hydrogen peroxide is a potential hazard for the body, which is why it is used to kill bacteria (WKU, 2010).Cells would die if hydrogen peroxide is not broken down by catalase.hen the enzyme concentration increased the rate of catalase activity increased too. When catalase was subjected to an increase of temperature changes, the rate of reaction increased.
