Photobacterium phosphoreum - Wikipedia
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.

2010年9月16日 · Photobacterium phosphoreum is one of many organisms that produce bioluminescence in marine organisms. P. phosphoreum is a light organ symbiont, living in the gut of the fish where metabolites are provided in exchange for bioluminescence, which is used for communication, prey attraction, and predator avoidance.[7]
Photobacterium phosphoreum - an overview | ScienceDirect …
Polar and lateral flagella of the deep-sea bacterium Photobacterium profundum work to promote swimming and swarming at high pressure. Flagella are important for multiple steps in surface colonization and biofilm development on abiotic surfaces and in hosts.
Isolation and Identification of Photobacterium phosphoreum …
Six luminous bacteria were isolated from migrating salmon in the Yukon River, Alaska. All isolates were identified as Photobacterium phosphoreum. Previous studies suggest that P. phosphoreum is an exclusively marine bacterium, while our Alaskan isolates are from salmon which migrated up to 1,228 km from the marine environment.
Photobacterium phosphoreum - an overview | ScienceDirect …
Photobacterium phosphoreum: this microorganism is the SSO that limits the shelf life of fresh marine fish when stored in modified atmosphere packaging (MAP). Three models are available: fresh MAP cod fillets, fresh MAP plaice fillets, fresh MAP salmon steaks.
The biology and the importance of Photobacterium species
2017年5月11日 · Some members of Photobacterium species such as P. kishitanii, P. leiognathi, P. mandapamensis and P. phosphoreum that produce light participate in a symbiotic relationship with marine organisms (e.g. fish and squid) (Dunlap et al. 2004; Kaeding et al. 2007). In this relationship, the animal provides nutrients and oxygen to the luminous bacteria ...

In this work, a lux gene cassette without any specific promoter transforms three different bacterial hosts: E. coli, Agrobacterium tumefaciens, and Bacillus subtilis. They combined those genetically engineered hosts with naturally bioluminescent Vibrio fisheri.
Photobacterium - Wikipedia
Photobacterium is a genus of gram-negative, oxidase positive and catalase positive bacteria in the family Vibrionaceae. [1] Members of the genus are bioluminescent, that is they have the ability to emit light.
Genome Sequence of Luminous Piezophile Photobacterium phosphoreum …
2014年4月17日 · Here, we present the genome sequence of a luminous, piezophilic Photobacterium phosphoreum strain, ANT-2200, isolated from a water column at 2,200 m depth in the Mediterranean Sea. It is the first genomic sequence of the P. phosphoreum group.
Photobacterium phosphoreum - Citizendium
2024年10月4日 · Photobacterium phosphoreum is a luminescent bacterium. It is a straight rod and Gram-negative bacterium with a large size and round shape. It is motile. It can grow at a low temperature around 4˚C, but no at 35˚C or above. It emits the brightest light from all bioluminescent bacteria. Its optimum temperature is at 18-25˚C .
