Why are strict aerobes oxidase positiveSolutionFirst we have

Solution

First we have to know why strict aerobes oxidase positive,it is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain,this does NOT mean that they are strict aerobes,the oxidase negative result just means that these organisms do not have the cytochrome c oxidase that oxidizes the test reagent.

The strict aerobes oxidase positive because the oxidase is an enzyme that is critical to cellular respiration.
