Turtle was created on a Muller Hinton Agar using three different species of Pseudomonas aeruginosa and Staphylococcus aureus for the outline. Pseudomonas aeruginosa is the only species of Pseudomonas that will produce pyocyanin, which is what creates Sammy’s green color. These bacteria are found naturally in the environment, especially in lakes, ponds, and soil. They are also found in insufficiently cleaned pools or hot tubs, making them a major cause of swimmer’s ear.
