Pseudomonas mediterranea Catara et al. 2002 was previously known as
Pseudomonas corrugata phenon B.
Gram-negative cells. PHB is accumulated.
Nonfluorescent, smooth or wrinkled colonies, frequently produce yellow to brown
pigments.
Aerobic, optimal growth temperature 26 ºC.
Media: Trypticase Soy Agar, Nutrient agar, King’s B agar.
Isolated from soil & plants.
Bacteria is the causal agent of tomato pith necrosis. May produce onion rot, lettuce and alfalfa necrosis, experimental tobacco leaves
hypersensitivity.
