Salegentibacter holothuriorum sp. nov., isolated from the edible holothurian Apostichopus japonicus.

Strain KMM 3524T was isolated from the holothurian Apostichopus japonicus living in the Sea of Japan. The bacterial strain was pigmented, non-motile, Gram-negative, strictly aerobic and oxidase-, catalase- and beta-galactosidase-positive. From the results of 16S rDNA sequence analysis, strain KMM 3524T was found to be related closely to Salegentibacter salegens (98.

Cellulophaga pacifica sp. nov.

Three marine, heterotrophic, aerobic, agarolytic, pigmented and gliding bacteria were isolated in June 2000 from a sea water sample that was collected in the Gulf of Peter the Great, Sea of Japan, and analysed in a polyphasic taxonomic study. 16S rDNA sequence analysis indicated that strains KMM 3664(T), KMM 3669 and KMM 3915 were members of the family Flavobacteriaceae. Based on phenotypic, chemotaxonomic, genotypic and phylogenetic data, the isolates were classified in the genus Cellulophaga as members of a novel species, Cellulophaga pacifica sp.

Arenibacter troitsensis sp. nov., isolated from marine bottom sediment.

A novel marine, heterotrophic, aerobic, pigmented, non-motile bacterium was isolated from a bottom sediment sample collected from Troitsa Bay in the Gulf of Peter the Great, Sea of Japan, during June 2000. 16S rDNA sequence analysis revealed that this bacterium was a member of the family FLAVOBACTERIACEAE: On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic analyses, the bacterium was shown to belong to a novel species of the genus Arenibacter, for which the name Arenibacter troitsensis sp. nov.

Vitellibacter vladivostokensis gen. nov., sp. nov., a new member of the phylum Cytophaga-Flavobacterium-Bacteroides.

A novel heterotrophic, yellow-orange-pigmented, non-motile, asporogenic, strictly aerobic, Gram-negative, oxidase and catalase-positive bacterium KMM 3516(T) was isolated from the holothurian Apostichopus japonicus collected from Troitsa Bay in the Gulf of Peter the Great (Sea of Japan) during November 1997. 16S rDNA sequence analysis revealed that strain KMM 3516(T) was a member of the family FLAVOBACTERIACEAE: The DNA G+C content of KMM 3516(T) was 41.3 mol%.

Reichenbachia agariperforans gen. nov., sp. nov., a novel marine bacterium in the phylum Cytophaga-Flavobacterium-Bacteroides.

A heterotrophic, pigmented, agarolytic, gliding bacterium was isolated from a seawater sample collected from the Gulf of Peter the Great, Sea of Japan, during June 2000. 16S rDNA sequence analysis indicated that the novel bacterium, strain KMM 3525T, was a member of the phlyum Cytophaga-Flavobacterium-Bacteroides. On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic data, it is proposed that the marine bacterium represents the sole species of a novel genus, Reichenbachia, the type species of which is Reichenbachia agariperforans (KMM 3525T =IFO 16625T =JCM 11238T).
