Photobacterium phosphoreum is a Gram-negative, bioluminescent bacterium living in symbiosis with deep-sea marine organisms, such as anglerfish.^[1] It can emit bluish-green light (490 nm) due to a chemical reaction between FMN, luciferin and molecular oxygen catalysed by an enzyme called luciferase.

Ecology[edit]

P. phosphoreum appears to be distributed worldwide in oceans and is found in a variety of different marine habitats.^[1] It was first isolated in 1878 from seawater, but has also been reported from the surfaces of fish and other marine animals, the intestines of fish, coastal seawater, and from a state of bioluminescent symbiosis with fish. P. phosphoreum colonizes a wide variety of deep-sea fishes which generally occur in the mesopelagic and bentho-pelagic zones.^[1]

As a bioindicator[edit]

P. phosphoreum is the most frequently used luminescent bacterium in water quality assessment.^[2]
