Describe the significance of a positive catalase test. What is of catalase in bacterial metabolism?

Solution

The benefit of a catalase positive test is that these bacteria belongs to the category of strict aerobes as well as facultative anaerobes thus they have the ability to respire and oxygen in this acts as a terminal electron acceptor.

Catalase is produced by the microorganisms to neutralize the toxic form of oxygen metabolites for example hydrogen peroxide. Thus this inhibits the bactericidal effects of the hydrogen peroxide and protects the bacteria.
