Corallibacter vietnamensis gen. nov., sp. nov., a marine bacterium of the family Flavobacteriaceae.
International journal of systematic and evolutionary microbiology, 2011Co-Authors: Olga I Nedashkovskaya, Natalia V Zhukova, Andrey D Kuchlevskiy, Valery V. MikhailovAbstract:The taxonomic position of two strains of a novel heterotrophic, strictly aerobic, Gram-negative, gliding, dark-orange-pigmented bacterium, designated KMM 6217(T) and KMM 6332, was determined. The strains grew at 10-40 °C and with 0.5-8.0% NaCl. They were catalase- and oxidase-positive, produced flexirubin-type pigments and hydrolysed aesculin, gelatin, starch, Tween 80 and DNA. The predominant fatty acids were iso-C(15:1), iso-C(15:0), C(15:0), summed feature 3 (comprising iso-C(15:0) 2-OH and/or C(16:1)ω7c) and iso-C(17:0) 3-OH. The polar lipid profile comprised phosphatidylethanolamine as the major component, three unknown aminolipids and one unknown lipid. The DNA G+C content was 34.7-34.8 mol%. Phylogenetic analysis of the 16S rRNA gene sequence showed that the novel isolates could be placed in the family Flavobacteriaceae. The nearest neighbours of strains KMM 6217(T) and KMM 6332 were members of the genera Bizionia, Formosa, Lacinutrix, Meridianimaribacter, Mesoflavibacter and Winogradskyella, with sequence similarities to the type strains of species of these genera of 92.8-95.2, 93.7-94.5, 94.1-94.7, 94.9, 94.6 and 93.5-94.4%, respectively. Based on phenotypic, genotypic and phylogenetic data, strains KMM 6217(T) and KMM 6332 should be classified as representatives of a novel species in a new genus in the family Flavobacteriaceae of the phylum 'Bacteroidetes', for which the name Corallibacter vietnamensis gen. nov., sp. nov. is proposed; the type strain is KMM 6217(T) (=JCM 17525(T)=KCTC 23026(T)).

Antonie van Leeuwenhoek, 2014Co-Authors: Olga I Nedashkovskaya, Andrey D. Kukhlevskiy, Natalia V ZhukovaAbstract:A facultatively anaerobic, Gram-stain negative, rod-shaped and yellow pigmented bacterium, designated strain IDSW-73^T, was isolated from a seawater sample and subjected to a polyphasic taxonomic study. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the novel strain formed a distinct phyletic line in the family Flavobacteriaceae and is most closely related to the members of the genus Leeuwenhoekiella , with 16S rRNA gene sequence similarity of 91.4–92.6 %. Strain IDSW-73^T was found to be able to grow with 0–12 % NaCl and at 4–33 °C; and was able to hydrolyse gelatin, starch and Tweens 20, 40 and 80. The DNA G+C content was determined to be 42.2 mol%. The predominant cellular fatty acids were identified as branched-chain saturated and unsaturated and straight-chain unsaturated fatty acids such as iso-C_15:0, iso-C_15:1, iso-C_17:1 ω9c_, C_15:1 ω6c, iso-C_15:0 3-OH, iso-C_17:0 3-OH and summed feature 3 (as defined by MIDI), comprising iso-C_15:0 2-OH and/or C_16:1 ω7c . The polar lipids found were phosphatidylethanolamine, two unknown aminolipids and one unknown lipid. The major respiratory quinone was identified as MK-6. The significant molecular distinctiveness between the novel isolate and its nearest neighbours were strongly supported by notable differences in physiological and biochemical tests. Therefore, strain IDSW-73^T is considered to represent a novel genus and species within the family Flavobacteriaceae , for which the name Flavimarina pacifica gen. nov., sp. nov. is proposed. The type strain is IDSW-73^T (=KCTC 32466^T = KMM 6759^T). Emended descriptions of the recognized species of the genus Leeuwenhoekiella are also proposed.

distribution of intracellular fucoidan hydrolases among marine bacteria of the family Flavobacteriaceae
Applied Biochemistry and Microbiology, 2006Co-Authors: A M Urvantseva, Olga I Nedashkovskaya, Yu I Bakunina, T N ZvyagintsevaAbstract:A search for fucoidan-degrading enzymes and other O-glycosylhydrolases has been performed among 51 strains of marine bacteria of the family Flavobacteriaceae isolated from red, green, and brown algae, as well as from the sea urchin Strongylocentrotus intermedius and the holothurian Apostichopus japonicus. Over 40% of the studied strains synthesized fucoidanases. The marine bacteria Mesonia algae KMM 3909T (an isolate from green alga Acrosiphonia sonderi), as well as Maribacter sp. KMM 6211 and Gramella sp. KMM 6054 (associants of the sea urchin S. intermedius), were the best producers of fucoidanases. Xylose effectively induced the biosynthesis of fucoidanases in these strains. None of the 15 strains of marine bacteria belonging to the genus Arenibacter produced polysaccharide hydrolases.

leeuwenhoekiella blandensis sp nov a genome sequenced marine member of the family Flavobacteriaceae
International Journal of Systematic and Evolutionary Microbiology, 2006Co-Authors: Jarone Pinhassi, J P Bowman, Olga I Nedashkovskaya, Itziar Lekunberri, Laura Gomezconsarnau, Carlos PedrosalioAbstract:Bacteria in the family Flavobacteriaceae are increasingly recognized to play important roles in the degradation of organic matter during and following algal blooms. A novel heterotrophic, rod-shaped, aerobic, yellow-pigmented and gliding bacterium was isolated from a seawater sample collected in the Bay of Blanes in the north-western Mediterranean Sea. Analysis of its 16S rRNA gene sequence, retrieved from the whole-genome sequence, showed that the bacterium was closely related to members of the genus Leeuwenhoekiella within the family Flavobacteriaceae, phylum Bacteroidetes. Phenotypic, genotypic, chemotaxonomic and phylogenetic analyses supported the creation of a novel species to accommodate this bacterium, for which the name Leeuwenhoekiella blandensis sp. nov. is proposed. The type strain is MED 217T (=CECT 7118T=CCUG 51940T).

Sandarakinotalea sediminis gen. nov., sp. nov., a novel member of the family Flavobacteriaceae.
International journal of systematic and evolutionary microbiology, 2020Co-Authors: Shams Tabrez Khan, Yasuyoshi Nakagawa, Shigeaki HarayamaAbstract:Four Gram-negative, orange-coloured, aerobic, heterotrophic bacteria were isolated from sediment samples collected on the Pacific coast of Japan near the cities of Toyohashi and Katsuura. 16S rRNA gene sequence analysis indicated that these strains form a distinct lineage within the family Flavobacteriaceae. The four isolates shared 99.9-100 % 16S rRNA gene sequence similarity with each other and showed 88-90.9 % similarity with their neighbours in the family Flavobacteriaceae. The four strains also shared high DNA-DNA reassociation values of 67-99 % with each other. All the strains grew at 37 degrees C but not at 4 degrees C, and degraded gelatin, starch and DNA. The major fatty acids were i-C15:0, a-C15:0, i-C16:0 and i-C17:0 3-OH. However, two common fatty acids of members of the Flavobacteriaceae, i-C15:1 and a-C15:1, were absent in these strains. The DNA G+C contents of the four strains were in the range 35-37 mol%. On the basis of the polyphasic evidence, it was concluded that these strains should be classified as a novel genus and a novel species in the family Flavobacteriaceae, for which the name Sandarakinotalea sediminis gen. nov., sp. nov. is proposed. The type strain of Sandarakinotalea sediminis is CKA-5T (=NBRC 100970T=LMG 23247T).

International Journal of Systematic and Evolutionary Microbiology, 2008Co-Authors: Shams Tabrez Khan, Yasuyoshi Nakagawa, Shigeaki HarayamaAbstract:A novel bacterium, MTT-39T, was isolated from a sample of marine sediment collected at Tottori on the coast of the Sea of Japan. Cells were Gram-negative, rod-shaped and non-motile. The bacterium formed yellowish brown colonies on marine agar 2216. Although the 16S rRNA gene sequence of strain MTT-39T classified this strain as a member of the family Flavobacteriaceae, the maximum sequence similarity obtained was only 91.5 % (with Kordia algicida OT-1T). In the maximum-likelihood tree based on 16S rRNA gene sequences, the novel bacterium clustered with the type strains of Kordia algicida, Lutibacter litoralis, Tenacibaculum maritimum and Polaribacter filamentus. The novel strain exhibited the following characteristics: the predominant fatty acids in cells grown on artificial seawater-based tryptic soya agar were iso-C15 : 1, iso-C15 : 0 and iso-C15 : 0 3-OH, the major respiratory quinone was MK-6 and the DNA G+C content was 35 mol%. On the basis of its distinct phenotypic traits and the phylogenetic distance between this marine isolate and other recognized taxa, strain MTT-39T represents a novel genus and species of the family Flavobacteriaceae, for which the name Fulvibacter tottoriensis gen. nov., sp. nov. is proposed. The type strain of the type species is MTT-39T (=NBRC 102624T=KCTC 22214T=CGMCC 1.7058T).

The predominant cellular fatty acids were i15 : 0, a15 : 0, i15 : 1, 15 : 0, 15 : 1ω6c, i15 : 0 3-OH and i17 : 0 3-OH. The DNA base compositions were 31–33 mol% G+C. Based on the phenotypic, genotypic, chemotaxonomic and phylogenetic analyses, the novel bacteria should be placed in a novel taxon as Algibacter lectus gen. nov., sp. nov. with type strain KMM 3902T (=KCTC 12103T=DSM 15365T).

formosa agariphila sp nov a budding bacterium of the family Flavobacteriaceae isolated from marine environments and emended description of the genus formosa
International Journal of Systematic and Evolutionary Microbiology, 2006Co-Authors: Olga I Nedashkovskaya, Galina M. Frolova, Valery V. Mikhailov, Hyun Woo Oh, A M Lysenko, Manfred Rohde, Natalia V Zhukova, Marc Vancanneyt, Cindy Snauwaert, Jean SwingsAbstract:Two marine, heterotrophic, aerobic, yellow-pigmented, agarolytic bacterial strains that are motile by means of gliding were isolated from the green alga Acrosiphonia sonderi and from sea water. Comparative 16S rRNA gene sequence analysis revealed an affiliation between the strains studied and the genus Formosa, a member of the family Flavobacteriaceae. The level of sequence similarity between strain KMM 3901T and Formosa algae KMM 3553T was 99·1 %. The results of DNA–DNA hybridization experiments and phenotypic analysis indicated that the strains represent a novel species of the genus Formosa, for which the name Formosa agariphila sp. nov. is proposed, with KMM 3901T (=KCTC 12365T=LMG 23005T=DSM 15362T) as the type strain. The description of the genus Formosa is emended with newly obtained data.

polaribacter butkevichii sp nov a novel marine mesophilic bacterium of the family Flavobacteriaceae
Current Microbiology, 2005Co-Authors: Olga I Nedashkovskaya, A M Lysenko, Nataliya I Kalinovskaya, Valery V. MikhailovAbstract:A novel heterotrophic, yellow pigmented, aerobic, Gram-negative, nonmotile, oxidase- and catalase-positive bacterium KMM 3938T was isolated from sea water collected in the Sea of Japan, Russia. The strain grew at mesophilic temperature range, and required the presence of NaCl for growth. 16S rRNA gene sequence analysis revealed that strain KMM 3938T is a member of the family Flavobacteriaceae. The predominant fatty acids were C13:0 iso, C14:0 iso, C15:0 iso, C15:0, C15:1Δ6, 3OH-C15:0:3 iso, and 3OH-C15:0. The G + C content of the DNA of KMM 3938T was 32.4 mol%. On the basis of phenotypic, chemotaxonomic, genotypic, and phylogenetic characteristics, the novel bacterium was assigned to the genus Polaribacter as Polaribacter butkevichii sp. nov. The type strain is KMM 3938T (= KCTC 12100T = CCUG 48005T).

zobellia amurskyensis sp nov zobellia laminariae sp nov and zobellia russellii sp nov novel marine bacteria of the family Flavobacteriaceae
International Journal of Systematic and Evolutionary Microbiology, 2004Co-Authors: Olga I Nedashkovskaya, Valery V. Mikhailov, A M Lysenko, Makoto Suzuki, Marc Vancanneyt, Ilse Cleenwerck, Jean SwingsAbstract:The taxonomic position of four newly isolated marine, heterotrophic, gliding, Gram-negative, aerobic, pigmented, agarolytic bacteria was established. 16S rRNA gene sequence analysis indicated affiliation of the isolates to the genus Zobellia in the family Flavobacteriaceae. DNA–DNA hybridization experiments revealed that the strains studied represent three distinct and novel species, for which the names Zobellia amurskyensis sp. nov., Zobellia laminariae sp. nov. and Zobellia russellii sp. nov. are proposed, with KMM 3526T (=LMG 22069T=CCUG 47080T), KMM 3676T (=LMG 22070T=CCUG 47083T) and KMM 3677T (=LMG 22071T=CCUG 47084T), respectively, as the type strains.
