AbstractStrains representative of species of the marine genera Beneckea and Photobacterium were used as reference standards in in vitro DNA/DNA competition experiments. Within a given species, strains were found to be related by over 80% competition. (Competition was defined as the amount of radioactive DNA displaced by heterologous DNA relative to the amount displaced by homologous DNA.) On the basis of interspecies competition values (expressed as averages), the following groupings could be… 

Phylogenetic resolution and habitat specificity of members of the Photobacterium phosphoreum species group.

The results of this fine-scale phylogenetic analysis support the emerging view that bacterial species names should designate singular historical entities, i.e. discrete lineages diagnosed by a significant divergence of shared derived nucleotide characters.

Genomic and Phylogenetic Characterization of Luminous Bacteria Symbiotic with the Deep-Sea Fish Chlorophthalmus albatrossis (Aulopiformes: Chlorophthalmidae)

Luminous bacteria symbiotic with C. albatrossis, together with certain other strains of luminous bacteria, form a clade that is related to but evolutionarily distinct from P. phosphoreum, and may constitute the major or sole bioluminescent symbiont of several families of deep-sea luminous fishes.

Genomic taxonomy of vibrios

The combination of different analytical and bioinformatics tools will enable the most accurate species identification through genomic computational analysis and will culminate in the birth of the online genomic taxonomy.

Phylogenetic Diversity and Cosymbiosis in the Bioluminescent Symbioses of “Photobacterium mandapamensis”

The results, which are the first report of bacterial cosymbiosis in fish light organs and the first demonstration that P. leiognathi is not the exclusive light organ symbiont ofLeiognathid fishes, demonstrate that the host species ranges of P. mandapamensis and P.LeIognathi are substantially distinct.

Phylogenetic analysis of the lux operon distinguishes two evolutionarily distinct clades of Photobacterium leiognathi

It is demonstrated that P. leiognathi contains two evolutionarily and phenotypically distinct clades, P. mandapamensis and P. gyrB, which are based on a high degree of phenotypic and genetic similarity and which are distinct from each other.

Photobacterium alginatilyticum sp. nov., a marine bacterium isolated from bottom seawater.

A Gram-straining-negative, facultatively aerobic, rod-shaped strain, motile by a polar flagellum and designated P03D4T, was isolated from the bottom seawater of the East China Sea and is proposed as representing a novel species of the genus Photobacterium.

Systematic relationships within the Vibrionaceae (Bacteria: Gammaproteobacteria): steps toward a phylogenetic taxonomy

A phylogenetic hypothesis is presented for all 95 species of the family Vibrionaceae based on a combined analysis of eight molecular loci for up to 9337 nucleotide characters, suggesting a new definition for Photobacterium that includes all species of Aliivibrio.

Photobacterium lipolyticum sp. nov., a bacterium with lipolytic activity isolated from the Yellow Sea in Korea.

On the basis of phenotypic properties and phylogenetic and genomic distinctiveness, strain M37T should be placed in the genus Photobacteria as a novel species, for which the name Photobacterium lipolyticum sp.



Nucleic Acid Homologies Among Oxidase-Negative Moraxella Species

The deoxyribonucleic acid (DNA) base composition and DNA homologies of more than 40 strains of oxidase-negative Moraxella species were determined and evidence of a distant relationship between the two groups was obtained in competition experiments by using ribosomal ribon nucleic acid.

Deoxyribonucleic Acid Relationships Among Marine Vibrios

Most strains isolated from diseased salmon in the Pacific Northwest proved to be virtually identical with V. anguillarum type C by DNA homology experiments, thereby differentiating them from similar strains isolated From diseased herring and occasionally from salmon.

Taxonomy of Marine Bacteria: the Genus Beneckea

Nine groups which had deoxyribonucleic acid (DNA) containing 45 to 48 moles per cent guanine plus cytosine (GC) were assigned to a redefined genus Beneckea, and all of the strains in this genus, when grown in liquid medium, had a single, polar flagellum.

Taxonomy of the marine, luminous bacteria

Four species of luminous, marine bacteria isolated from sea water, surfaces and intestines of fish, as well as from the luminous organs of fish and squid were submitted to an extensive phenotypic characterization, supported by differences in the properties of the Luminous system.

Taxonomy of Marine Bacteria: Beneckea parahaemolytica and Beneckea alginolytica

A collection of 169 strains, including 91 obtained from cases of gastroenteritis and 41 from localized tissue infections and infections of the eye and ear, was submitted to an extensive nutritional, physiological, and morphological characterization and could be readily distinguished from one another as well as from the remaining species of the genus Beneckea by multiple, unrelated, phenotypic traits.

Structure and Arrangement of Flagella in Species of the Genus Beneckea and Photobacterium fischeri

Only one group (B-2) of marine bacteria included in this study was found to have polar, unsheathed flagella.

Taxonomy of the aerobic pseudomonads: Pseudomonas cepacia, P. marginata, P. alliicola and P. caryophylli.

It is concluded that P. cepacia is so similar to P. multivorans that the latter name should be regarded as a synonym and P. alliicola appears to be a synonyms of P. marginata.

Taxonomy of Aerobic Marine Eubacteria

Two hundred and eighteen strains of nonfermentative marine bacteria were submitted to an extensive morphological, physiological, and nutritional characterization, finding that the majority of these groups were separable by a large number of unrelated phenotypic traits.


The results indicated that this collection of strains, which included the type strain of Beneckea parahaemolytica, was phenotypically homogeneous and distinguishable from the other known species of BenECkea by multiple, unrelated, phenotypic traits.

The aerobic pseudomonads: a taxonomic study.

SUMMARY A collection of 267 strains, representing many of the principal biotypes among aerobic pseudomonads, has been subjected to detailed study, with particular emphasis on biochemical,
