Macromorphology (smell):
  
  | Large, flat and greenish colonies (2-4 mm in diameter) with irregular edges and typical metallic luster. The color is most visible on for instance TS-agar. Sometimes, a clear hemolysis zone is obtained on blood agar. Has distinctive smell (caramel, strawberry or raspberry soda). Some strains produce a green fluorescent pigment, pyoverdine. Some strains can also produce a blue pigment, pyocyanin. |

| Micromorphology:
| Small motile rod (0.5-0.8 x 1.5-3 µm) with a monotrichous flagellum. |

| Metabolism:

Is often classified as aerobic, but can also exploit NO3- as final electron acceptor in the respiratory chain. Should, therefore, be classified as facultatively anaerobic! |

| Virulence Factors:
| is a toxic pigment, which induces oxidative stress in cells by generating H2O2 and superoxide radicals.
Pyoverdine is a so-called siderophore, which forms a part of the bacterial iron metabolism. |
