Salinimicrobium marinum sp. nov., a halophilic bacterium of the family Flavobacteriaceae, and emended descriptions of the genus Salinimicrobium and Salinimicrobium catena.

Int J Syst Evol Microbiol 2010 Oct 13;60(Pt 10):2303-2306. Epub 2009 Nov 13.

Two novel heterotrophic, facultatively anaerobic, gliding and yellow-pigmented bacteria, designated strains KMM 6270(T) and KMM 6320, were isolated from different marine environments and studied using a polyphasic taxonomic approach. 16S rRNA gene sequence analysis placed the strains within the family Flavobacteriaceae. Strains KMM 6270(T) and KMM 6320 were most closely related to the type strains of recognized species of the genus Salinimicrobium (95.0-96.6 % 16S rRNA gene sequence similarity). The G+C content of the genomic DNA was 40-41 mol%. The strains grew with 0.5-15 % (w/v) NaCl (optimum 4 % NaCl) and at 4-41 °C (optimum 28-32 °C). Aesculin and gelatin were hydrolysed, but agar, casein, DNA and chitin were not. The phylogenetic data taken together with the results of the genotypic and phenotypic studies permit the classification of strains KMM 6270(T) and KMM 6320 as members of a novel species of the genus Salinimicrobium, for which the name Salinimicrobium marinum sp. nov. is proposed. The type strain is KMM 6270(T) (=KCTC 12719(T)=LMG 25395(T)).

Pseudozobellia thermophila gen. nov., sp. nov., a bacterium of the family Flavobacteriaceae, isolated from the green alga Ulva fenestrata.

Int J Syst Evol Microbiol 2009 Apr;59(Pt 4):806-10

Pacific Institute of Bioorganic Chemistry of the Far-Eastern Branch of the Russian Academy of Sciences, Pr. 100 let Vladivostoku 159, 690022 Vladivostock, Russia.

Two novel aerobic, dark-orange-pigmented, Gram-negative bacterial strains, designated KMM 3531(T) and KMM 3953, were isolated from the green alga Ulva fenestrata. Analysis of the 16S rRNA gene sequences showed that the strains represented a novel lineage within the family Flavobacteriaceae. The most closely related genera with validly published names were Costertonia, Flagellimonas, Kriegella, Maribacter, Muricauda and Zobellia, with 16S rRNA gene sequence similarities of 93.3-91.8 %. Cells of strains KMM 3531(T) and KMM 3953 were rod-shaped, motile by gliding and grew at temperatures up to 49 degrees C. They produced acid from carbohydrates and possessed oxidase, catalase, beta-galactosidase and agarase activities. The predominant cellular fatty acids were iso-C(15 : 0,) iso-C(17 : 0) 3-OH, iso-C(15 : 1) G, summed feature 3 (comprising C(16 : 1)omega7c and/or iso-capital ES, Cyrillic(15 : 0) 2-OH), iso-C(17 : 1)omega9c and iso-C(15 : 0) 3-OH. The DNA G+C content was 47-49 mol%. On the basis of phenotypic and genotypic characteristics, strains KMM 3531(T) and KMM 3953 represent a novel genus and species, for which the name Pseudozobellia thermophila gen. nov., sp. nov. is proposed. The type strain is KMM 3531(T) (=DSM 19858(T)=JCM 11733(T)=KCTC 22016(T)).

Salegentibacter agarivorans sp. nov., a novel marine bacterium of the family Flavobacteriaceae isolated from the sponge Artemisina sp.

Int J Syst Evol Microbiol 2006 Apr;56(Pt 4):883-887

Korea Research Institute of Bioscience and Biotechnology, 52 Oun-Dong, Yusong, Daejon 305-333, Republic of Korea.

A sponge-associated strain, KMM 7019T, was investigated in a polyphasic taxonomic study. The bacterium was strictly aerobic, heterotrophic, Gram-negative, yellow-pigmented, motile by gliding and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KMM 7019T is closely related to members of the genus Salegentibacter, namely Salegentibacter holothuriorum, Salegentibacter mishustinae and Salegentibacter salegens (97.7-98 % sequence similarities). The DNA-DNA relatedness between the strain studied and Salegentibacter species ranged from 27 to 31 %, clearly demonstrating that KMM 7019T belongs to a novel species of the genus Salegentibacter, for which the name Salegentibacter agarivorans sp. nov. is proposed. The type strain is KMM 7019T (=KCTC 12560T = LMG 23205T).

Arenibacter palladensis sp. nov., a novel marine bacterium isolated from the green alga Ulva fenestrata, and emended description of the genus Arenibacter.

Int J Syst Evol Microbiol 2006 Jan;56(Pt 1):155-60

Pacific Institute of Bioorganic Chemistry of the Far-Eastern Branch of the Russian Academy of Sciences, Pr. 100 Let Vladivostoku 159, 690022 Vladivostok, Russia.

The taxonomic position of three novel, marine, heterotrophic, aerobic, pigmented, gliding bacteria, isolated from the green alga Ulva fenestrata in the Sea of Japan, was determined. 16S rRNA gene sequence analysis revealed that the strains belong to the genus Arenibacter. The results of DNA-DNA hybridization experiments supported by phenotypic and chemotaxonomic data showed that the isolates represent a novel species of the genus Arenibacter, for which the name Arenibacter palladensis sp. nov. is proposed. The type strain is KMM 3961T (= LMG 21972T = CIP 108849T).

Pontibacter actiniarum gen. nov., sp. nov., a novel member of the phylum 'Bacteroidetes', and proposal of Reichenbachiella gen. nov. as a replacement for the illegitimate prokaryotic generic name Reichenbachia Nedashkovskaya et al. 2003.

Int J Syst Evol Microbiol 2005 Nov;55(Pt 6):2583-2588

Pacific Institute of Bioorganic Chemistry of the Far-Eastern Branch of the Russian Academy of Sciences, Pr. 100 Let Vladivostoku 159, 690022, Vladivostok, Russia.

The taxonomic position of a marine, gliding, pink-pigmented, aerobic, heterotrophic and Gram-negative bacterium was established using a polyphasic approach. 16S rRNA gene sequence analysis indicated that the strain was a member of the phylum 'Bacteroidetes' in which it occupied a separate lineage. The predominant cellular fatty acids were C15 : 0 iso, C17 : 0 iso 3-OH, summed feature 3 and summed feature 4. The DNA G+C content was 48.7 mol%. Phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analyses strongly support the assignment of the newly isolated bacterium as a member of a novel genus and species, for which the name Pontibacter actiniarum gen. nov., sp. nov. is proposed. The type strain is KMM 6156T (=KCTC 12367T=LMG 23027T). It is also proposed that the illegitimate names Reichenbachia and Reichenbachia agariperforans are replaced with Reichenbachiella and Reichenbachiella agariperforans, respectively.

Roseivirga ehrenbergii gen. nov., sp. nov., a novel marine bacterium of the phylum 'Bacteroidetes', isolated from the green alga Ulva fenestrata.

Int J Syst Evol Microbiol 2005 Jan;55(Pt 1):231-234

Korean Collection for Type Cultures, Biological Resources Center, Korea Institute of Bioscience and Biotechnology, Yusong, Daejon 305-333, Republic of Korea.

The taxonomic position of a novel marine bacterium isolated from the green alga Ulva fenestrata collected in the Sea of Japan was established. Cells of the strain studied, designated KMM 6017T, were strictly aerobic, heterotrophic, pink-pigmented, non-motile by gliding, Gram-negative and oxidase-, catalase-, beta-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence analysis indicated that the strain occupied a distinct lineage within the phylum 'Bacteroidetes' and formed a cluster with [Flexibacter] tractuosus and Reichenbachia agariperforans. The G+C content of the DNA of KMM 6017T was 40.2 mol%. The major respiratory quinone was MK-7. The predominant fatty acids were i15 : 1, i15 : 0 and i17 : 0 3-OH (34.2, 24 and 7.7 %, respectively). On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacterium was assigned to the genus Roseivirga gen. nov., as Roseivirga ehrenbergii gen. nov., sp. nov. The type strain is KMM 6017T (=KCTC 12282T=LMG 22567T).
