Seawater samples from a variety of locations contained viable luminous bacteria, but luminescence was not detectable although the system used to measure light was sensitive enough to measure light from a single, fully induced luminous bacterial cell. When the symbiotically luminous fishCleidopus gloriamaris was placed in a sterile aquarium, plate counts of water samples showed an increase in luminous colony-forming units. Luminescence also increased, decreasing when the fish was removed. Light… 
13 Luminous Bacteria
Current understanding of the biochemistry and genetics of bacterial light emission, the taxonomy and phylogenetics of light-emitting bacteria, the evolutionary origins and hypothesized physiological and ecological functions of bacterial luminescence are summarized.
Developmental and Microbiological Analysis of the Inception of Bioluminescent Symbiosis in the Marine Fish Nuchequula nuchalis (Perciformes: Leiognathidae)
Results indicate that light organs of N. nuchalis flexion and postflexion larvae are at an early stage of development and that inception of the symbiosis apparently occurs in flexion larvae of 6.0 to 6.5 mm in notochord length, and that Ontogeny of the light organ therefore apparently precedes acquisition of the Symbiotic bacteria.
Phylogenetic divergence between the obligate luminous symbionts of flashlight fishes demonstrates specificity of bacteria to host genera.
Different genera of anomalopids were found to harbour different species of bacteria, even when the hosts overlapped in geographic range, suggesting that the divergence between bacterial species is not the result of geographic isolation.
Reviews and syntheses: Bacterial bioluminescence – ecology and impact in the biological carbon pump
Abstract. Around 30 species of marine bacteria can emit light, a critical characteristic in the oceanic environment is mostly deprived of sunlight. In this article, we first review current knowledge
Phylogeny, genomics, and symbiosis of Photobacterium.
Phylogenetic analysis demonstrates a robust separation between Photobacterium and its close relatives, Aliivibrio and Vibrio, and reveals the presence of two well-supported clades.
Epibiotic Vibrio Luminous Bacteria Isolated from Some Hydrozoa and Bryozoa Species
Scanning electron microscopy analysis and results of culture-based and culture-independent approaches enabled us to establish that luminous vibrios represent major constituents of the bacterial community inhabiting the A. octodonta surface suggesting that the interactions between luminous bacteria and the examined hydrozoan and bryozoan species are highly specific.
Phylogenetic analysis of host–symbiont specificity and codivergence in bioluminescent symbioses
In several associations, bacterial species identities contradicted strict host family bacterial species specificity and the hypothesis of codivergence in bioluminescent symbioses was refuted.
Population genomics of a bioluminescent symbiosis sheds light on symbiont transmission and specificity
Using restriction site-associated sequencing (RAD-Seq) methods, it is demonstrated that the facultative symbiont of S. tubifer exhibits genetic structure at spatial scales of tens of kilometers in Okinawa, Japan in the absence of physical dispersal barriers and in contrast to the host fish.
Vibrio harveyi Associated with Aglaophenia octodonta (Hydrozoa, Cnidaria)
A previously unknown association between a luminous bacterium, Vibrio harveyi, and a benthic hydrozoan, Aglaophenia octodonta, is described and may function as habitat “islands” providing a unique set of environmental conditions for luminous bacteria colonization.
Culturable heterotrophic bacteria in seawater and Mytilus galloprovincialis from a Mediterranean area (Northern Ionian Sea – Italy)
The results obtained contribute to improve the knowledge on both the bacterial abundance and diversity in mussels and the surrounding seawater in the Northern Ionian Sea.


Symbiotic association of Photobacterium fischeri with the marine luminous fish Monocentris japonica; a model of symbiosis based on bacterial studies.
Isolation of bacteria from the luminous organ of the fish Monocentris japonica has revealed that the organ contains a pure culture of luminous bacteria, the first time that P. fischeri has been identified in a symbiotic association.
The isolated symbiotic bacteria were compared with free living bacteria isolated directly from sea water in the same area where the fish were collected, and it was possible to estimate the total number of viable bacteria within an organ, and to compare this with the weight of the organ.
Planktonic Marine Luminous Bacteria: Species Distribution in the Water Column
The apparent vertical stratification of two taxa of oceanic luminous bacteria may reflect not only differences in physiology, but also depth-related, species-specific symbiotic associations.
Luminous Enteric Bacteria of Marine Fishes: a Study of Their Distribution, Densities, and Dispersion
It was determined that luminous cells entering the fish during ingestion of seawater or contaminated particles traversed the alimentary tract and survived the digestive processes and became distributed into the surrounding seawater.

Physiological Characteristics Underlying the Distribution Patterns of Luminous Bacteria in the Mediterranean Sea and the Gulf of Elat
The winter appearance of Photobacterium fischeri and the succession of winter and summer types of Beneckea harveyi in the eastern Mediterranean are explained by different temperature requirements for growth.
A taxonomic study by computer analysis of marine bacteria from New Zealand waters
Most strains of the luminous bacteria have been accommodated in the species Vibrio fischeri and Photobacterium phosphoreum, which were common in deepwater samples but were also isolated from fish light organs.

Seasonal and Geographic Distribution of Luminous Bacteria in the Eastern Mediterranean Sea and the Gulf of Elat
The composition of the luminous bacteria communities may serve as indicators of different marine water bodies and the symbiotic luminousacteria of the light organ of the common Gulf of Elat fish, Photoblepharon palbebratus steinitzi, is different from any of the types described.
