If your sample does not grow on the plate in the anaerobic chamber but does grow in the presence of oxygen, it produces bubbles
jasenka [17]

Answer:

it is an obligate (or strict) aerobe

Explanation:

By whether an organism requires oxygen or not for respiration. We can classify it as either aerobic or anaerobic.

Aerobic organisms require oxygen and anaerobic do not.

For aerobes, it can be facultative or obligate. Facaltative aerobes require oxygen but they can however switch to fermentation when oxygen is not available.

Obligate aerobes are aerobes require oxygen for cellular metabolism.

In the test the dextrose tube remained yellow because fermentation had not taken place.

Therefore we can conclude the sample contained an obligate aerobe which was catalase positive since it produces bubbles when Hydrogen peroxide was added.
