Oxidase Test

In this video, Biology Professor (Twitter: @DrWhitneyHolden) will cover the Oxidase test procedure and discuss the background information to understand how this test works. Specifically, this diagnostic test indicates the presence of cytochome c oxidase in a bacterial culture. This is an enzyme that participates in the electron transport chain during aerobic respiration. This test is used to differentiate oxidase-positive bacteria, like Pseudomonas and Neisseria spp., from oxidase-negative bacteria.
