There are none.
An oxidase test relies on a reagent that will change colors when it is oxidized. The reagent used in the test only reacts to cytochrome c oxidase by acting in place of oxygen to receive electrons from the cytochrome.
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
The ability of bacteria to produce cytochrome oxidase can be determined by the addition of the test reagent p-aminodimethylaniline oxalate to colonies grown on a plate medium.
API 20E and Enterotube II are for the identification of oxidase- negative bacteria. If the oxidase test is positive, these two methods of identification would be useless.

It is NEGATIVE
yes, all aerobic cells are oxidase positive. The oxidase test is testing for the presence of cytochrome oxidase [by reducing it with an artificial substrate which turns purple when oxidised]. In aerobic cells cytochrome oxidase's normal role is in the electron transport chain, passing electrons from cytochrome c to oxygen. hence if the cell is aerobic then oxygen is terminal electron acceptor in the cells ETC and thus it will give a positive result in the oxidase test.
