Oxidase - Wikipedia
https://en.wikipedia.org/wiki/Oxidase
WebIn biochemistry, an oxidase is an oxidoreductase (any enzyme that catalyzes a redox reaction) that uses dioxygen (O 2) as the electron acceptor. In reactions involving donation of a hydrogen atom, oxygen is reduced to water (H 2 O) or hydrogen peroxide (H 2 O 2).

WebAug 10, 2022 · The oxidase test is used to determine if an organism possesses the cytochrome 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.
