Gaiella occulta gen. nov., sp. nov., a novel representative of a deep branching phylogenetic lineage within the class Actinobacteria and proposal of Gaiellaceae fam. nov. and Gaiellales ord. nov

Two isolates, with an optimum growth temperature of about 35-37 °C and an optimum pH for growth between 6.5 and 7.5, were recovered from a deep mineral water aquifer in Portugal. Strains form rod-shaped cells and were non-motile. These strains were non-pigmented, strictly aerobic, catalase and oxidase positive. Strains F2-233^T and F2-223 assimilated carbohydrates, organic acids and amino acids. Major fatty acids were novel iso internally branched such as 17:0 iso 10-methyl, 17:0 iso and 15:0 iso 8-methyl. The peptidoglycan contained meso-diaminopimelic acid and menaquinone MK-7 was the major respiratory quinone. Analysis of the 16S rRNA gene shows the strains to cluster with species of the genera Thermoleophilum, Patulibacter, Conexibacter and Solirubrobacter to which they have pairwise sequence similarity in the range 87-88%. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics we describe a new species of a novel genus represented by strain F2-233^T (=CECT 7815^T = LMG 26412^T) for which we propose the name Gaiella occulta gen. nov., sp. nov. We also propose that this organism represents a novel family named Gaiellaceae fam. nov. of a novel order named Gaiellales ord. nov.     

Sufflavibacter maritimus gen. nov., sp. nov., novel Flavobacteriaceae bacteria isolated from marine environments

Four Gram-negative, chemoheterotrophic, nonmotile, yellow-colored strains were isolated from the East Sea or from deep-sea sediments of Nankai Trough by standard dilution plating. Characterization by polyphasic approaches indicated that the four strains are members of the same species. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strains formed a coherent and novel genus-level lineage within the family Flavobacteriaceae. The dominant cellular fatty acids were i-C15:0, 3-OH i-C17:0, and 2-OH i-C15:0 and/or C16:1 omega7c. Predominance of 2-OH i-C 15:0 and/or C16:1omega7c clearly differentiated the strains from closely related members. The DNA G+C contents ranged 35.1-36.2 mol%. It is proposed, from the polyphasic evidence, that the strains should be placed into a novel genus and species named Sufflavibacter maritimus gen. nov., sp. nov., with strain IMCC 1001T (=KCCM 42359T=NBRC 102039T) as the type strain.     

Oceaniferula marina gen.nov., sp.nov., an anti-fluoroquinolone bacterium isolated from marine sediment

Antonie van Leeuwenhoek - A Gram-stain-negative, aerobic, rod-shaped, non-gliding and non-motile bacterium designated as N1E253T, was isolated from marine sediments collected from the coast of...     

Dasania marina gen. nov., sp. nov., of the order Pseudomonadales, isolated from Arctic marine sediment

An obligately aerobic bacterium, strain KOPRI 20902T, was isolated from a marine sediment in Ny-Arlesund, Spitsbergen Islands, Norway. Cells were irregular rods and motile with polar monotrichous flagellum. The optimum growth temperature was 17-22 degrees . Cells grew best in pH 7.0-10.0 and 3-4% sea salts (corresponding to 2.3-3.1% NaCl). The novel strain required Ca2+ or Mg2+ in addition to NaCl for growth. Sequence analysis of 16S rRNA gene revealed that the Arctic isolate is distantly related with established species (<92.4% sequence similarity) and formed a monophyletic group with Cellvibrio, which formed a distinct phylogenetic lineage in the order Pseudomonadales. Predominant cellular fatty acids [C16:1 omega7c/15:0 iso 2OH (45.3%), C16:0 (18.4%), ECL 11.799 (11.2%), C10:0 3OH (10.4%)]; DNA G+C content (37.0 mol%); nitrate reduction to nitrogen; absence of aesculin hydrolysis, N-acetyl-beta-glucosaminidase and esterase; no assimilation of arabinose, galactose, glucose, lactose, maltose, and trehalose differentiated the strain from the genus Cellvibrio. Based on the phylogenetic and phenotypic characteristics, Dasania marina gen. nov., sp. nov. is proposed in the order Pseudomonadales. Strain KOPRI 20902T (=KCTC 12566T=JCM 13441T) is the type strain of Dasania marina.     

Defluviimonas denitrificans gen. nov., sp. nov., and Pararhodobacter aggregans gen. nov., sp. nov., non-phototrophic Rhodobacteraceae from the biofilter of a marine aquaculture

Three Gram-negative bacterial strains were isolated from the biofilter of a recirculating marine aquaculture. They were non-pigmented rods, mesophiles, moderately halophilic, and showed chemo-organoheterotrophic growth on various sugars, fatty acids, and amino acids, with oxygen as electron acceptor; strains D9-3^T and D11-58 were in addition able to denitrify. Phototrophic or fermentative growth could not be demonstrated. Phylogenetic analysis of the 16S rRNA gene sequences placed D9-3^T and D11-58, and D1-19^T on two distinct branches within the alpha-3 proteobacterial Rhodobacteraceae, affiliated with, but clearly separate from, the genera Rhodobacter, Rhodovulum, and Rhodobaca. Based on morphological, physiological, and 16S rRNA-based phylogenetic characteristics, the isolated strains are proposed as new species of two novel genera, Defluviimonas denitrificans gen. nov., sp. nov. (type strain D9-3^T = DSM 18921^T = ATCC BAA-1447^T; additional strain D11-58 = DSM19039 = ATCC BAA-1448) and Pararhodobacter aggregans gen. nov., sp. nov (type strain D1-19^T = DSM 18938^T = ATCC BAA-1446^T).     

Mzabimyces algeriensis gen. nov., sp. nov., a halophilic filamentous actinobacterium isolated from a Saharan soil,and proposal of Mzabimycetaceae fam. nov.

Three halophilic mycelium-forming actinobacteria, strains H195^T, H150 and H151, were isolated from a Saharan soil sample collected from Béni-isguen in the Mzab region (Ghardaïa, South of Algeria) and subjected to a polyphasic taxonomic characterisation. These strains were observed to show an aerial mycelium differentiated into coccoid spore chains and fragmented substrate mycelium. Comparative analysis of the 16S rRNA gene sequences revealed that the highest sequence similarities were to Saccharopolyspora qijiaojingensis YIM 91168^T (92.02 % to H195^T). Phylogenetic analyses showed that the strains H195^T, H150 and H151 represent a distinct phylogenetic lineage. The cell-wall hydrolysate was found to contain meso-diaminopimelic acid, and the diagnostic whole-cell sugars were identified as arabinose and galactose. The major cellular fatty acids were identified as iso-C_15:0, iso-C_16:0, iso-C_17:0 and anteiso-C_17:0. The diagnostic phospholipid detected was phosphatidylcholine and MK-9 (H₄) was found to be the predominant menaquinone. The genomic DNA G+C content of strain H195^T was 68.2 mol%. On the basis of its phenotypic features and phylogenetic position, we propose that strain H195^T represents a novel genus and species, Mzabimyces algeriensis gen. nov., sp. nov., within a new family, Mzabimycetaceae fam. nov. The type strain of M. algeriensis is strain H195^T (=DSM 46680^T = MTCC 12101^T).     

Endozoicomonas elysicola gen. nov., sp. nov., a gamma-proteobacterium isolated from the sea slug Elysia ornata

A Gram-negative, strictly aerobic, rod-formed bacterium, strain MKT110(T), was isolated from a mollusk, the sea slug Elysia ornata collected in seawater off the coast of Izu-Miyake Island, Japan at a depth of 15m. Comparative 16S rRNA gene sequences analysis indicated that the isolate MKT110(T) constituted a novel lineage in gamma-proteobacteria related to the genera Zooshikella, Oceanospirillum, Microbulbifer, Marinobacter, Saccharospirillum and Pseudomonas. The strain MKT110(T) was closely related to the clones from marine sponge Halichondria okadai (AB054136, AB054161) and the coral Pocillopora damicornis (AY700600, AY700601). The phylogenetic tree based on the 16S rRNA gene sequences showed that MKT110(T) and four clones formed a sub-lineage related to the genus Zooshikella, with a bootstrap value of 100%. MKT110(T) required salt for its growth and was mesophilic. The bacterium contained 16:1omega7c, 16:0 and 14:0 as major cellular fatty acids, and 3-OH 14:0, 3-OH 10:0 and 3-OH 12:0 as major hydroxy fatty acids. The DNA base composition of the isolate was 50.4 mol% G+C. The major quinone was Q-9. The bacterium is distinguished from currently recognized bacterial genera based on phylogenetic and phenotypic features and should be classified in a novel genus for which the name Endozoicomonas elysicola gen. nov., sp. nov. is proposed. (type strain MKT110(T)=IAM 15107(T)=KCTC 12372(T); GenBank accession no. AB196667).     

Mesoflavibacter zeaxanthinifaciens gen. nov., sp. nov., a novel zeaxanthin-producing marine bacterium of the family Flavobacteriaceae

A novel strictly aerobic, gliding, Gram-negative, rod-shaped, halo- and mesophilic bacterium (TD-ZX30(T)) was isolated from a seawater sample collected on the Pacific coastline of Japan near Kamakura City (Fujisawa, Kanagawa). The temperature range for growth of TD-ZX30(T) was between 16 and 44 degrees C. The DNA G+C content was 32.0mol%. The predominant fatty acids were iso-C(15:1) G, iso-C(15:0), iso-C(16:0) 3-OH, iso-C(15:0) 3-OH, Summed feature (iso-C(15:0) 2-OH and/or C(16:1)omega7c), iso-C(17:0) 3-OH, and C(15:0). MK-6 was the only respiratory quinone. Zeaxanthin was the major carotenoid pigment produced but flexirubin-type pigments were not produced. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that TD-ZX30(T) belonged to a distinct lineage in the family Flavobacteriaceae, sharing 93.9% sequence similarity with the nearest species Olleya marilimosa. TD-ZX30(T) could be distinguished from the other members of the family Flavobacteriaceae by a number of chemotaxonomic and phenotypic characteristics. The results of polyphasic taxonomic analyses suggested that TD-ZX30(T) represents a novel genus and a novel species, for which the name Mesoflavibacter zeaxanthinifaciens gen. nov., sp. nov. is proposed. The type strain is TD-ZX30(T) (=NBRC 102119=CCUG 53614=DSM 18436).     

Halorubellus salinus gen. nov., sp. nov. and Halorubellus litoreus sp. nov., novel halophilic archaea isolated from a marine solar saltern

Two extremely halophilic archaeal strains GX3(T) and GX26(T) were isolated from the Gangxi marine solar saltern near the Weihai city of Shandong Province, China. Cells from the two strains were pleomorphic and stained Gram-negative, colonies were red-pigmented. Strains GX3(T) and GX26(T) were able to grow at 25-50 °C (optimum 37 °C), at 1.4-5.1M NaCl (optimum 3.1M), at pH 5.5-9.5 (optimum pH 7.0) and neither strain required Mg(2+) for growth. Cells lyse in distilled water and the minimal NaCl concentration to prevent cell-lysis was 8% (w/v). The major polar lipids of the two strains were PA (phosphatidic acid), PG (phosphatidylglycerol), PGP-Me (phosphatidylglycerol phosphate methyl ester) and three major glycolipids (GL1, GL2 & GL3) chromatographically identical to S-TGD-1 (sulfated galactosyl mannosy glucosyl diether), S-DGD-1 (sulfated mannosyl glucosyl diether), and DGD-1 (mannosyl glucosyl diether) respectively, an unidentified lipid (GL4) was also detected in strain GX26(T). Phylogenetic analysis based on 16S rRNA gene revealed that strain GX3(T) and strain GX26(T) formed a distinct clade with the closest relative, Haladaptatus paucihalophilus (89.9-92.4% and 90.4-92.7, respectively). The rpoB' gene similarities between strains GX3(T) and GX26(T), and between the two strains and the closest relative, Halorussus rarus TBN4(T) are 96.5%, 84.3% and 83.9%, respectively. The DNA G+C contents of strain GX3(T) and strain GX26(T) are 67.3 mol% and 67.2 mol%, respectively. The DNA-DNA hybridization value between strain GX3(T) and strain GX26(T) was 44%. The phenotypic, chemotaxonomic and phylogenetic properties suggest that strain GX3(T) and strain GX26(T) represent two novel species in a new genus within the family Halobacteriaceae, Halorubellus salinus gen. nov., sp. nov. (type strain GX3(T)=CGMCC 1.10384(T)=JCM 17115(T)) and Halorubellus litoreus sp. nov. (type strain GX26(T)=CGMCC 1.10386(T)=JCM 17117(T)).     

Thermosediminibacter oceani gen. nov., sp. nov. and Thermosediminibacter litoriperuensis sp. nov., new anaerobic thermophilic bacteria isolated from Peru Margin

A new group of anaerobic thermophilic bacteria was isolated from enrichment cultures obtained from deep sea sediments of Peru Margin collected during Leg 201 of the Ocean Drilling Program. A total of ten isolates were obtained from cores of 1–2 m below seafloor (mbsf) incubated at 60°C: three isolates came from the sediment 426 m below sea level with a surface temperature of 9°C (Site 1227), one from 252 m below sea level with a temperature of 12°C (Site 1228), and six isolates under sulfate-reducing condition from the lower slope of the Peru Trench (Site 1230). Strain JW/IW-1228P from the Site 1228 and strain JW/YJL-1230-7/2 from the Site 1230 were chosen as representatives of the two identified clades. Based on the 16S rDNA sequence analysis, these isolates represent a novel group with Thermovenabulum and Caldanaerobacter as their closest relatives. The temperature range for growth was 52–76°C with an optimum at around 68°C for JW/IW-1228P and 43–76°C with an optimum at around 64°C for JW/YJL-1230-7/2. The pH^25C range for growth was from 6.3 to 9.3 with an optimum at 7.5 for JW/IW-1228P and from 5 to 9.5 with an optimum at 7.9–8.4 for JW/YJL-1230-7/2. The salinity range for growth was from 0% to 6% (w/v) for JW/IW-1228P and from 0% to 4.5% (w/v) for JW/YJL-1230-7/2. The G+C content of the DNA was 50 mol% for both JW/IW-1228P and JW/YJL-1230-7/2. DNA–DNA hybridization yielded 52% similarity between the two strains. According to 16S rRNA gene sequence analysis, the isolates are located within the family, Thermoanaerobacteriaceae. Based on their morphological and physiological properties and phylogenetic analysis, it is proposed that strain JW/IW-1228P^T is placed into a novel taxa, Thermosediminibacter oceani, gen. nov., sp. nov. (DSM 16646^T=ATCC BAA-1034^T), and JW/YJL-1230-7/2^T into Thermosediminibacter litoriperuensis sp. nov. (DSM 16647^T =ATCC BAA-1035^T).An erratum to this article can be found at     

Proteinivorax tanatarense gen. nov., sp. nov., an anaerobic, haloalkaliphilic, proteolytic bacterium isolated from a decaying algal bloom, and proposal of Proteinivoraceae fam. nov.

Two strains of a novel anaerobic, protein- and nucleoside-utilizing bacterium, Z-910^T and Z-810, were isolated. The strains were spore-forming, mainly nonmotile rods, exhibiting positive Gram reaction with Gram-positive cell wall structure. The strains were mesophilic and haloalkaliphilic. Cultures used proteins and proteinaceous substrates as carbon, nitrogen, and energy sources. Both strains used also ribonucleosides, cellobiose, pyruvate, and glycerol. Ribose and nucleobases did not support growth. The fermentation products from all utilized substrates were identical but varied in content and included straight and branched acids, as well as hydrogen and ammonia. When grown on tryptone, strain Z-910^T was able to reduce fumarate, dimethyl sulfoxide, thiosulfate, and elemental sulfur. Neither nitrate nor sulfate was reduced. The DNA G + C content of strain Z-910^T was 32.2 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence similarity revealed that strains Z-910^T and Z-810 represented a new branch within the order Clostridiales, with 90.2 % similarity to the nearest genus with a validly published name Anaerobranca gottschalkii DSM 13577^T. According to their physiological, chemotaxonomic, and phylogenetic properties, strains Z-910^T and Z-810 represented a new genus and novel species, for which the name Proteinivorax tanatarense gen. nov., sp. nov. was proposed. Phylogenetic analysis showed that the genera Proteinivorax gen. nov. and Anaerobranca formed a separate cluster within the order Clostridiales. The family Proteinivoraceae fam. nov. comprising the genera Proteinivorax gen. nov. and Anaerobranca was therefore proposed within the order Clostridiales of the phylum Firmicutes with Proteinivorax as a type genus of the new family.     

Citreitalea marina gen. nov., sp. nov., a novel member of the family Flavobacteriaceae isolated from a marine red alga and emended description of the genus Gangjinia

A Gram-negative, strictly aerobic, pale-yellow pigmented, rod-shaped bacterium designated A4O-5^T was isolated from a red coloured marine alga (Chondrus ocellatus Holmes). Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain was affiliated with the family Flavobacteriaceae and shared approximately 90 % sequence similarity with Leptobacterium flavescens YM3-0301^T and Gangjinia marincola GJ16^T. The strain could be differentiated phenotypically from the related members of the family Flavobacteriaceae. The major fatty acids of strain A4O-5^T were identified as iso-C15:0, iso-C17:0 3-OH and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c). A complex polar lipid profile was present consisting of phosphatidylethanolamine, an unidentified phospholipid, three unidentified amino lipids and an unidentified lipid. The DNA G+C content of the strain was determined to be 41.9 mol% and the major respiratory quinone was identified as menaquinone 6 (MK-6). From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus in the family Flavobacteriaceae, for which the name Citreitalea marina gen. nov., sp. nov. is proposed. The type strain of C. marina is A4O-5^T (=KCTC 32483^T=NBRC 109918^T).     

Bacillus oceani sp. nov., a new slightly halophilic bacterium, isolated from a deep sea sediment environment

A strictly aerobic, Gram-stain positive, slightly halophilic strain, designated SCSIO 04524^T, was isolated from a deep sea sediment sample collected from the northern South China Sea at a depth of 3415 m. The isolate slightly embedded into the medium after 72 h incubation at 30 °C. Growth was found to occur on media with 0–10 % NaCl but extremely weak growth occurred without supplying NaCl. The predominant menaquinone was determined to be MK-7. The major cellular fatty acid identified was iso-C_15:0. The diagnostic polar lipids were determined to be diphosphatidylglycerol, phosphatidyl methylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content was determined to be 38 mol%. 16S rRNA gene sequences analysis showed that this strain had the highest similarities with Bacillus carboniphilus JCM 9731^T (94.7 %) and Bacillus endophyticus 2DT^T (94.3 %). Phylogenetic analysis revealed that strain SCSIO 04524^T formed a distinct lineage with Bacillus chungangensis CAU 348^T and B. carboniphilus JCM 9731^T. Physiological characteristics including utilization of sole nitrogen and carbon sources, and chemotaxonomic properties of cellular fatty acids and polar lipids could readily distinguish strain SCSIO 04524^T from its most closely related species. Based on this polyphasic taxonomic data, a new species, Bacillus oceani sp. nov., is proposed, with the type strain SCSIO 04524^T (=DSM 26213^T = KCTC 33077^T).     

Aestuariihabitans beolgyonensis gen. nov., sp. nov., a novel alphaproteobacterium isolated from tidal flat sediment

A Gram-negative, non-motile and rod-shaped bacterial strain, designated BB-MW15^T, was isolated from a tidal flat of the southern coast of the Korean peninsula, and its taxonomic position was investigated by using a polyphasic taxonomic approach. Strain BB-MW15^T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2–3 % (w/v) NaCl. Strain BB-MW15^T exhibited the highest 16S rRNA gene sequence similarity values to the type strains of Marivita byunsanensis (96.8 %), Thalassobius maritimus (96.6 %), Sulfitobacter marinus (96.4 %) and Marinovum algicola (96.3 %). Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain BB-MW15^T forms an independent lineage within the evolutionary radiation encompassed by the Roseobacter clade of the class Alphaproteobacteria. Strain BB-MW15^T contained Q-10 as the predominant ubiquinone and C_18:1 ω7c as the predominant fatty acid. The major polar lipids detected in strain BB-MW15^T were phosphatidylcholine, phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid. The DNA G+C content of strain BB-MW15^T is 62.7 mol%. Based on phylogenetic, chemotaxonomic and other phenotypic characteristics, strain BB-MW15^T represents a new genus and a new species within Alphaproteobacteria, for which the name Aestuariihabitans beolgyonensis gen. nov., sp. nov. is proposed. The type strain of A. beolgyonensis is BB-MW15^T (= KCTC 32324^T = CCUG 63829^T).     

Croceibacter atlanticus gen. nov., sp. nov., a novel marine bacterium in the family Flavobacteriaceae

A bright, saffron-colored marine bacterium HTCC2559T was isolated from the Bermuda Atlantic Time Series station in the western Sargasso Sea, Atlantic Ocean by high throughput culturing methods and characterized by polyphasic approaches. Phenotypic data and phylogenetic analyses showed that the strain is a member of the family Flavobacteriaceae. The strain was gram-negative, non-motile, chemoheterotrophic, strictly aerobic, NaCl-requiring, rod-shaped cells that contain carotenoid pigments but not flexirubin. Several kinds of macromolecules (gelatin, DNA, starch, casein, and elastin) were degraded and carbohydrates, sugar alcohols, organic acids, and amino acids were utilized as sole carbon sources. The dominant fatty acids were branched or hydroxy acids, and 3-OH i17:0, i15:0, i15:1, and i17:1 omega9c were abundant. The DNA G+C content of the strain is 34.8 mol%. Phylogenetic analyses using three treeing algorithms based on 16S rRNA gene sequences revealed that the strain formed a very distinct lineage that is allied closely with several seawater environmental clones in the family Flavobacteriaceae. Therefore, it is proposed from the polyphasic studies that strain HTCC2559T (=ATCC BAA-628T = KCTC 12090T) belongs to a new genus and species named Croceibacter atlanticus gen. nov., sp. nov.     

Rufibacter tibetensis gen. nov., sp. nov., a novel member of the family Cytophagaceae isolated from soil

A red-pigmented, Gram-negative, strictly aerobic, rod-shaped bacterium which was motile by gliding, designated strain 1351^T, was isolated from the soil of Lengduo, Tibet in China and subjected to a polyphasic taxonomic analysis. The isolate grows optimally at 30°C and pH 7. It grows with NaCl tolerated up to 1.5% (optimum, 0.5%). Phylogenetic analysis based on the 16S rRNA gene sequence shows that strain 1351^T is closely related to members of the family ‘Cytophagaceae’ closest sequence similarity was observed with similarity with Adhaeribacter terreus (91.8%). The major whole-cell fatty acids are summed feature 4 (containing anteiso-C_17:1 B and/or iso-C_17:1 I, 29.2%), summed feature 3 (containing C_16:1ω6c and/or C_16:1ω7c, 13.0%) and iso-C_15:0 (12.0%). The predominant menaquinone of strain 1351^T is menaquinone-7 (MK-7) and the G+C content of the DNA is 46.8 mol%. According to the phylogenetic evidence and phenotypic data, strain 1351^T is considered to represent a new genus and species of the family ‘Cytophagaceae’ for which the name Rufibacter tibetensis gen nov., sp. nov. is proposed. The type species is R. tibetensis and the type strain is 1351^T (=CCTCC AB 208084^T = NRRL B-51285^T).

A Gram-negative, strictly aerobic, coccoid to short rod-shaped marine bacterium strain MKT107(T) was isolated from the molluscan top shell Omphalius pfeifferi pfeifferi collected on the coast of Japan. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain MKT107(T) constitutes a new lineage in alpha-Proteobacteria related to the genera Nereida, Roseobacter, Staleya, Oceanibulbus and Sulfitobacter. Strain MKT107(T) was found to require salt for its growth and to be mesophilic. It contained 18:1omega7c and 16:0 as major cellular fatty acids and 3-OH 10:0 and 3-OH 12:0 as hydroxy fatty acids. The DNA base composition of the isolate was 61.6 mol% G+C. The major quinone was Q-10. Sufficient differences existed to distinguish this strain from currently recognized bacterial genera. Therefore, the isolate is classified as representing a new genus and species, Tateyamaria omphalii gen. nov., sp. nov. (type strain MKT107(T) =IAM 15108(T) =KCTC 12333(T); GenBank accession no. AB193438).
