Pseudomonas aeruginosa is a Gram-negative, aerobic, rod-shaped bacterium with unipolar motility. An opportunistic human pathogen, P. aeruginosa is also an opportunistic pathogen of plants. It secretes a variety of pigments, including pyocyanin (blue-green), fluorescein (yellow-green and fluorescent, now also known as pyoverdin), and pyorubin (red-brown).
It is oftenpreliminarily identified by its pearle scent appearance and grape-like odor in vitro. Definitive clinical identification of P. aeruginosa often includes identifying the production of pyocyanin and fluorescein as well as its ability to grow at 42°C.
It is capable of growth in diesel and jet fuel, where it is known as a hydrocarbon utilizing microorganism (or "HUM bug"), causing microbial corrosion. It creates dark gellish mats sometimes improperly called "algae" because of their appearance.
