WebResult Evolution of a gas (Oxygen) causes bubbles – Positive No evolution of gas – Negative OXIDASE TEST Cytochrome oxidase is an enzyme found in some bacteria that transfers electrons to Oxygen, the final electron acceptor in some electron transport chains. Thus, the enzyme oxidises reduced cytochrome C to make this transfer of energy. WebOxidase test. The oxidase test is used to determine if an organism possesses the cytochrome c oxidase enzyme. The test is used as an aid for the differentiation of Neisseria, Moraxella, Campylobacter and Pasteurella species (oxidase positive). It is also used to differentiate pseudomonads from related species. [1]
