Photobacterium phosphoreum is a luminescent bacterium. Its physical characteristics are gram-negative, rod-like shape, plump and large (0.8-1.3 um in diameter and 1.8-2.4 um in length). It can be motile or non-motile. Those that are motile have 1-3 unsheathed polar flagella. Its optimum temperature is 18-25˚C. It emits a blue-green light. | Photobacterium phosphoreum is a luminescent bacterium.

Description and significance
Photobacterium phosphoreum is a luminescent bacterium. Its physical characteristics are gram-negative, rod-like shape, plump and large (0.8-1.3 um in diameter and 1.8-2.4 um in length). It can be motile or non-motile. Those that are motile have 1-3 unsheathed polar flagella. Its optimum temperature is 18-25˚C. It emits a blue-green light.
Its major significance is its symbiotic relationship with some marine animals like fishes and squids. They have specialized organs that provide P. phosphoreum with a safe place to reside and food; while these animals use the light that the bacteria provide for camouflage and even for attracting mates.
