Question

Pseudomonas aeruginosa causes the top of an open (aerobic) OF tube to turn yellow. However, an oil-covered (anaerobic) OF tube inoculated with the same strain remains entirely green. What is the best explanation for these results?

Answer 1

This bacterial strain oxidizes glucose.

Step-by-step explanation:

Pseudomonas aeruginosa belongs to the class of the gram negative bacteria and are found ubiquitous in nature. These bacteria can cause diseases in plant as well as in animals.

The bacteria has the ability to undergo the process of both the aerobic and anaerobic respiration depending on the availability of glucose. The presence of green color determines that the bacteria has oxidized the glucose present in the medium.
