Five bacterial strains were isolated from a non-toxigenic strain of the marine dinoflagellate Alexandrium tamarense (Lebour) Balech CCMP 116 (NEPCC C116), during a survey of the diversity of bacteria associated with paralytic shellfish toxin-producing cultures of Alexandrium spp. (Dinophyta). All strains were strictly aerobic, Gram-negative, straight or curved rods. Cells were dimorphic, with stalks (or prosthecae) and non-motile or non-stalked and motile, by means of a single polar flagellum… 

Figures and Tables from this paper

Robiginitomaculum antarcticum gen. nov., sp. nov., a member of the family Hyphomonadaceae, from Antarctic seawater.

From the taxonomic evidence collected in this study, it is suggested that strain IMCC3195T represents a new genus and novel species in the family Hyphomonadaceae, for which the name Robiginitomaculum antarcticum gen. nov. is proposed.

Asprobacter aquaticus gen. nov., sp. nov., a prosthecate alphaproteobacterium isolated from fresh water.

The combined genotypic and phenotypic data showed that strain DRW22-8T could be distinguished from all genera within the family Hyphomonadaceae and represented a novel genus, Asprobacter gen. nov.

Marinicauda pacifica gen. nov., sp. nov., a prosthecate alphaproteobacterium of the family Hyphomonadaceae isolated from deep seawater.

On the basis of the polyphasic data presented in this study, strain P-1 km-3(T) is proposed to represent a novel species in a new genus, Marinicauda pacifica gen. nov., within the family Hyphomonadaceae.

Brevundimonas abyssalis sp. nov., a dimorphic prosthecate bacterium isolated from deep-subsea floor sediment.

On the basis of polyphasic biological features and the 16S rRNA gene sequence comparison presented here, strain TAR-001(T) is considered to represent a novel species of the genus Brevundimonas, for which the name Brevondimonas abyssalis sp.

Euryhalocaulis caribicus gen. nov., sp. nov., a New Members of the Family Hyphomonadaceae Isolated from the Caribbean Sea

A new aerobic, Gram-negative, chemo-organotrophic, euryhaline bacterium, designated strain JL2009T, was isolated from surface water of the Caribbean Sea and represents a novel genus and species in the family Hyphomonadaceae.

Vitreimonas flagellata gen. nov., sp. nov., a novel member of the family Hyphomonadaceae isolated from an activated sludge sample.

Analyses of the phylogenetic data and differences in the chemotaxonomic and biochemical features from related genera in the family Hyphomonadaceae indicated that strain SYSU XM001T merits representation of a Novel species of a novel genus, for which the name Vitreimonas flagellata gen. nov. is proposed.

Paracoccus stylophorae sp. nov., isolated from the reef-building coral Stylophora pistillata.

It is evident from the genotypic, phenotypic and chemotaxonomic analysis that strain KTW-16(T) should be classified in a novel species of the genus Paracoccus, for which the name ParACoccus stylophorae sp.

Glycocaulis albus sp. nov., a moderately halophilic dimorphic prosthecate bacterium isolated from petroleum-contaminated saline soil.

Two novel bacterial strains, which shared 99.9 % 16S rRNA gene sequence similarity with each other, were isolated from petroleum-contaminated saline soil in Shengli Oilfield, eastern China and represent a novel species of the genus Glycocaulis, which is proposed with strain SLG210-30A1(T) ( = LMG 27741(T).

Henriciella marina gen. nov., sp. nov., a novel member of the family Hyphomonadaceae isolated from the East Sea

Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Iso4T formed a monophyletic clade in the family Hyphomonadaceae, supported by high bootstrap value and was most closely related to the genushyphomonas (92∼94%), a member of marine bacteria in thefamily.

Hellea balneolensis gen. nov., sp. nov., a prosthecate alphaproteobacterium from the Mediterranean Sea.

A novel aerobic, heterotrophic, prosthecate bacterium, designated 26III/A02/215(T), was isolated from surface water of the north-western Mediterranean Sea and a novel genus is proposed, Hellea gen. nov.



Alcanivorax borkumensis gen. nov., sp. nov., a new, hydrocarbon-degrading and surfactant-producing marine bacterium.

A new genus and species, Alcanivorax borkumensis, is described to include six heterotrophic bacterial strains isolated from enriched mixed cultures, obtained from sea water/sediment samples collected near the isle of Borkum (North Sea), using Mihagol-S (C14,15-n-alkanes) as principal carbon source.

Characterisation of bacterial communities associated with toxic and non-toxic dinoflagellates: Alexa

It is suggested that a number of different bacterial species are associated with dinoflagellates, some of which are common to each of the dinof lagellate cultures examined, whereas others appear to be unique to a particular din oflageLLate.

The phylogeny of marine and freshwater caulobacters reflects their habitat

Overall, the data are consistent with the interpretation that all of the caulobacters examined, with the possible exception of C. subvibrioides, are ancestrally related, albeit anciently, and that most often division by terrestrial and marine habitats corresponds to an early evolutionary divergence within the genus.

Phylogeny and polyphasic taxonomy of Caulobacter species. Proposal of Maricaulis gen. nov. with Maricaulis maris (Poindexter) comb. nov. as the type species, and emended description of the genera Brevundimonas and Caulobacter.

A polyphasic approach, comprising 16S rDNA sequencing, profiling restriction fragments of 16S-23S r DNA interspacer regions, lipid analysis, immunological profiling and salt tolerance characterizations, was used to clarify the taxonomy of 76 strains of the genera Caulobacter.

Evolutionary relationship of some stalked and budding bacteria (genera Caulobacter, “Hyphobacter”, Hyphomonas and Hyphomicrobium) as studied by the new integral taxonomical method

It was shown that the genera Caulobacter and Hyphomonas are closely related to each other, but they are both distant from Hyphomicrobium species.

Isolation and Characterization of Marine Caulobacters and Assessment of Their Potential for Genetic Experimentation

The marine caulobacters appeared appropriate as candidates for genetic manipulation and the expression of selected genes in the marine environment and conjugal transfer of broad-host-range plasmids between freshwater and marine caulOBacters was demonstrated in both directions.

Characterization of caulobacters isolated from wastewater treatment systems.

Although the strains were distinguishable, caulobacters from the wastewater treatment systems the authors examined were relatively homogenous, were similar to characterized laboratory strains, and, with exceptions, could probably be reliably detected as a group by gene probes derived from C. crescentus strains.

Characterization of the holdfast region of wild-type cells and holdfast mutants of Asticcacaulis biprosthecum

All holdfast mutants are capable of forming rosettes with wild-type cells, even though they are incapable of initiating attachment on their own, suggesting polymeric bridging as a likely mechanism for attachment.

16S ribosomal DNA amplification for phylogenetic study

By use of this method, the phylogenetic study of extremely fastidious or highly pathogenic bacterial species can be carried out without the need to culture them.
