In this short video, we demonstrate the oxidase test a well-known oxidase-positive bacterium. This test is used to detect the presence of the enzyme cytochrome c oxidase, which is involved in the electron transport chain.
🧪 Procedure:
Take a clean, sterile oxidase disc or filter paper.
Using a sterile loop or wooden stick, pick a small colony of Pseudomonas from a fresh agar plate.
Rub the colony gently on the disc or moistened filter paper.
Observe the color change within 10–30 seconds.
✅ Positive Result: A purple or dark blue color appears — indicates Pseudomonas is oxidase positive.
🧫 Test Organism: Pseudomonas spp.
