*   * Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
* Consider adding a topic to this template: there are already 307 articles in the main category, and specifying`|topic=` will aid in categorization.
* Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
* You must provide copyright attribution in the edit summary accompanying your translation by providing an interlanguage link to the source of your translation. A model attribution edit summary is `Content in this edit is translated from the existing Polish Wikipedia article at [[:pl:Vibrio phosphoreum]]; see its history for attribution.`

Photobacterium phosphoreum

Synonyms

* Vibrio phosphoreum

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]
