Photobacterium

(fō'tō-bak-tē'rē-ŭm),
A genus of motile and nonmotile, aerobic to facultatively anaerobic bacteria (family Pseudomonadaceae) containing gram-negative coccobacilli and occasional rods; under adverse conditions pleomorphic forms frequently occur. Motile cells have polar flagella. The metabolism of these organisms is fermentative. They are usually luminescent and occur symbiotically in tissues of luminous organs of cephalopods and deep-sea fish as well as on the skin and in the intestines of some marine fish. The type species is Photobacterium phosphoreum.
