Two bacterial strains, R2A1-13T and R2A45-3T, were isolated from greenhouse soils in Korea. The cells of both strains were Gram-negative, aerobic and rod-shaped. 16S rRNA gene sequence analysis placed the isolates in the genus Flavobacterium within the family Flavobacteriaceae. Strain R2A1-13T was found to be related to Flavobacterium columnare IAM 14301T, Flavobacterium saliperosum CGMCC1.3801T and Flavobacterium croceum EMB47T, with sequence similarities of 96.8, 95.0 and 94.6 %, respectively. Strain R2A45-3T was found to be related to F. croceum EMB47T and Flavobacterium aquatile ATCC 11947T, with sequence similarities of 94.7 and 94.6 %, respectively. Both strains contained iso-C15 : 0 and iso-C16 : 0 as the main fatty acids and contained a menaquinone with six isoprene units (MK-6) as the major isoprenoid quinone. The G+C contents of the DNA from strains R2A1-13T and R2A45-3T were 34 and 38 mol%, respectively. A polyphasic taxonomic study revealed that these strains belong to two novel species within the genus Flavobacterium, for which the names Flavobacterium terrae sp. nov. and Flavobacterium cucumis sp. nov. are proposed. The type strains of F. terrae sp. nov. and F. cucumis sp. nov. are R2A1-13T (=KACC 11731T=DSM 18829T) and R2A45-3T (=KACC 11732T=DSM 18830T), respectively.

A Gram-negative, non-motile bacterium, designated MJ17T, was isolated from sludge at the Daejeon sewage disposal plant in South Korea. Comparative 16S rRNA gene sequence analysis showed that strain MJ17T belonged to the genus Paracoccus in the family Rhodobacteraceae of the class Alphaproteobacteria. 16S rRNA gene sequence similarities between strain MJ17T and type strains of species of the genus Paracoccus were 94.1–97.4 %. The highest similarities were between strain MJ17T and Paracoccus homiensis DD-R11T, Paracoccus zeaxanthinifaciens ATCC 21588T and Paracoccus alcaliphilus JCM 7364T (97.4, 97.2 and 96.3 %, respectively). Strain MJ17T exhibited <22 % DNA–DNA relatedness with P. homiensis KACC 11518T and P. zeaxanthinifaciens JCM 21774T. The G+C content of the genomic DNA was 58.7 mol%. Strain MJ17T contained ubiquinone Q-10. The major fatty acids were C18 : 0 (11.3 %), C16 : 0 (10.2 %) and summed feature 7 (containing one or more of C18 : 1ω7c, C18 : 1ω9c and C18 : 1ω12t; 54.3 %). Poly-β-hydroxybutyrate granules are formed. On the basis of phenotypic and genotypic properties and phylogenetic distinctiveness, strain MJ17T should be classified in a novel species of the genus Paracoccus, for which the name Paracoccus caeni sp. nov. is proposed. The type strain is MJ17T ( = KCTC 22480T  = JCM 16385T  = KEMB 9004-001T).

Two yellow-pigmented, Gram-negative, rod-shaped bacterial strains, GH1-10T and GH29-5T, were isolated from greenhouse soils in Korea. 16S rRNA gene sequence analysis indicated that these strains were related to members of the genus Flavobacterium. Strain GH1-10T was most closely related to Flavobacterium psychrolimnae and Flavobacterium denitrificans, with sequence similarities of 95.9 and 95.2 %, respectively. Strain GH29-5T was most closely related to ‘Flavobacterium saliodium’, F. denitrificans and Flavobacterium frigoris, with sequence similarities of 94.3, 92.5 and 92.5 %, respectively. The major cellular fatty acids of GH1-10T were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and iso-C17 : 0 3-OH, and those of GH29-5T were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. Both strains contained menaquinone with six isoprene units (MK-6) as the sole quinone. The DNA G+C contents of GH1-10T and GH29-5T were 35 and 39 mol%, respectively. Based on the phylogenetic and phenotypic data presented, it is concluded that the two bacteria represent two separate novel species of the genus Flavobacterium. The names proposed to accommodate these organisms are Flavobacterium daejeonense sp. nov., with type strain GH1-10T (=KACC 11422T=DSM 17708T), and Flavobacterium suncheonense sp. nov., with type strain GH29-5T (=KACC 11423T=DSM 17707T).

A Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1396T) producing a yellow pigment, was isolated from the healthy internal stem tissue of post-harvest cotton (Gossypium hirsutum, cultivar ‘DES-119’) grown at the Plant Breeding Unit at the E. V. Smith Research Center in Tallassee (Macon county), AL, USA. 16S rRNA gene sequence analysis of strain JM-1396T showed high sequence similarity values to the type strains of Novosphingobium mathurense, Novosphingobium panipatense (both 98.6 %) and Novosphingobium barchaimii (98.5 %); sequence similarities to all other type strains of species of the genus Novosphingobium were below 98.3 %. DNA–DNA pairing experiments of the DNA of strain JM-1396T and N. mathurense SM117T, N. panipatense SM16T and N. barchaimii DSM 25411T showed low relatedness values of 8 % (reciprocal 7 %), 24 % (reciprocal 26 %) and 19 % (reciprocal 25 %), respectively. Ubiquinone Q-10 was detected as the dominant quinone; the fatty acids C18 : 1ω7c (71.0 %) and the typical 2-hydroxy fatty acid, C14 : 0 2-OH (11.7 %), were detected as typical components. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. The polyamine pattern contained the major compound spermidine and only minor amounts of other polyamines. All these data revealed that strain JM-1396T represents a novel species of the genus Novosphingobium. For this reason we propose the name Novosphingobium gossypii sp. nov. with the type strain JM-1396T ( = LMG 28605T = CCM 8569T = CIP 110884T).

Two bacterial strains, designated GH34-4T and GH41-7T, were isolated from greenhouse soil cultivated with cucumber. The bacteria were strictly aerobic, Gram-negative, rod-shaped and oxidase- and catalase-positive. 16S rRNA gene sequence analysis indicated that these strains belong to the genus Lysobacter within the Gammaproteobacteria. Strain GH34-4T showed highest sequence similarity to Lysobacter yangpyeongensis GH19-3T (97.5 %) and Lysobacter koreensis Dae16T (96.4 %), and strain GH41-7T showed highest sequence similarity to Lysobacter antibioticus DSM 2044T (97.5 %), Lysobacter enzymogenes DSM 2043T (97.5 %) and Lysobacter gummosus ATCC 29489T (97.4 %). Levels of DNA–DNA relatedness indicated that strains GH34-4T and GH41-7T represented species clearly different from L. yangpyeongensis, L. antibioticus, L. enzymogenes and L. gummosus. The major cellular fatty acids of strains GH34-4T and GH41-7T were iso-C16 : 0, iso-C15 : 0 and iso-C17 : 1 ω9c, and the major isoprenoid quinone was Q-8. The DNA G+C contents of GH34-4T and GH41-7T were 62.5 and 66.6 mol%, respectively. On the basis of the polyphasic taxonomic data presented, it is evident that each of these strains represents a novel species of the genus Lysobacter, for which the names Lysobacter niabensis sp. nov. (type strain GH34-4T=KACC 11587T=DSM 18244T) and Lysobacter niastensis sp. nov. (type strain GH41-7T=KACC 11588T=DSM 18481T) are proposed.

Limit-dilution procedures were used to isolate seven, helically coiled bacterial strains from faeces of swine that constituted two unidentified taxa. Comparative 16S rRNA gene sequence analysis showed highest similarity values with species of the genus Treponema indicating that the isolates are members of this genus. Strain 7CPL208T, as well as five further isolates, and 14V28T displayed the highest 16S rRNA gene sequence similarities with Treponema pectinovorum ATCC 33768T (92·3 %) and Treponema parvum OMZ 833T (89·9 %), respectively. Polar lipid profiles distinguished 7CPL208T and 14V28T from each other as well as from related species. Based on their phenotypic and genotypic distinctiveness, strains 7CPL208T and 14V28T are suggested to represent two novel species of the genus Treponema, for which the names Treponema berlinense sp. nov. and Treponema porcinum sp. nov. are proposed. The type strain for Treponema berlinense is 7CPL208T (=ATCC BAA-909T=CIP 108244T=JCM 12341T) and for Treponema porcinum 14V28T (=ATCC BAA-908T=CIP 108245T=JCM 12342T).

A novel bacterium, designated strain H3-R18T, was isolated from seashore sand collected from Homi cape, Pohang city, Korea. Cells were Gram-negative, aerobic, non-motile, cream-coloured, mesophilic and slightly halotolerant. 16S rRNA gene sequence analysis indicated that the organism was a member of the genus Pseudomonas, but the sequence showed ⩽96.3 % sequence similarity to that of the type strains of all recognized Pseudomonas species. Highest sequence similarities were to Pseudomonas brenneri CFML 97-391T (96.3 %) and Pseudomonas migulae CIP 105470T (96.3 %). The major fatty acids were summed feature 3 and C16 : 0, with lesser amounts of C12 : 0, C12 : 0 3-OH, C18 : 1ω7c and C14 : 0. The major isoprenoid quinone was Q-9. The DNA G+C content was 64.0 mol%. The phylogenetic, phenotypic and genetic properties of strain H3-R18T suggest that it represents a novel species, for which the name Pseudomonas pohangensis sp. nov. is proposed. The type strain is H3-R18T (=KACC 11517T=DSM 17875T).

A rod-shaped Gram-staining-negative, non-motile, aerobic and fucoidan-digesting strain, designated TC2T, was isolated from marine algae collected from the coast of the Sea of Okhotsk at Abashiri, Hokkaido, Japan. The bacterium formed yellow, translucent, circular and convex colonies. Comparative 16S rRNA gene sequence analysis indicated that the strain belonged to the genus Flavobacterium, with the highest sequence similarities of 97.1 to 97.3 % to the type strains of Flavobacterium frigidarium, Flavobacterium frigoris, Flavobacterium limicola and Flavobacterium psychrolimnae. DNA–DNA relatedness values between strain TC2T and the above-mentioned species were lower than 28 %. The genomic DNA G+C content was 33.9 mol%. The major respiratory quinone was menaquinone-6 and the predominant fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C15 : 0 3-OH and summed feature 3 (which comprises iso-C15 : 0 2-OH and/or C16 : 1 ω7c). Strain TC2T could be differentiated from related species by several phenotypic characteristics. Thus, on the basis of these results, strain TC2T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium algicola sp. nov. is proposed. The type strain is TC2T (=NBRC 102673T =CIP 109574T).

An orange-coloured, rod-shaped, non-motile, Gram-reaction-negative, strictly aerobic bacterial strain, designated JC2680T, was isolated from a seawater sample of Jeju Island, Korea. The isolate required sea salts for growth. Flexirubin-type pigments were absent. 16S rRNA gene sequence analysis indicated that the test strain belonged to the genus Aquimarina within the family Flavobacteriaceae, but shared relatively low levels of similarity (93.6–95.9 %) with the type strains of recognized Aquimarina species. The predominant cellular fatty acids [iso-C17 : 0 3-OH, iso-C15 : 0 and summed feature 9 (comprising 10-methyl C16 : 0 and/or iso-C17 : 1ω9c) and DNA G+C content (35 mol%) were consistent with the assignment of strain JC2680T to the genus Aquimarina. However, a number of phenotypic characteristics, namely inability to grow under microaerophilic conditions, differences in enzyme reactions, and absence of flexirubin-type pigments and gliding motility, clearly distinguished strain JC2680T from recognized species of the genus Aquimarina. The data presented thus indicate that strain JC2680T represents a novel species of the genus Aquimarina, for which the name Aquimarina addita sp. nov. is proposed. The type strain is JC2680T ( = KACC 14156T  = JCM 17106T).

A pink-pigmented, facultatively methylotrophic bacterium, designated strain JT1T, was isolated from a thallus of the liverwort Marchantia polymorpha L. and was analysed by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis placed the strain in a clade with Methylobacterium adhaesivum AR27T, Methylobacterium fujisawaense DSM 5686T, Methylobacterium radiotolerans JCM 2831T and Methylobacterium jeotgali S2R03-9T, with which it showed sequence similarities of 97.8, 97.7, 97.2 and 97.4 %, respectively. However, levels of DNA–DNA relatedness between strain JT1T and these and the type strains of other closely related species were lower than 70 %. Cells of JT1T stained Gram-negative and were motile, rod-shaped and characterized by numerous fimbriae-like appendages on the outer surface of their wall (density up to 200 µm−2). Major fatty acids were C18 : 1ω7c and C16 : 0. Based on the morphological, physiological and biochemical data presented, strain JT1T is considered to represent a novel species of the genus Methylobacterium, for which the name Methylobacterium marchantiae sp. nov. is proposed. The type strain is JT1T ( = DSM 21328T  = CCUG 56108T).

Strain BZ30T was isolated from hydrocarbon-contaminated soil. The Gram-negative, aerobic bacterium was psychrophilic and able to grow at temperatures ranging from 1 to 30 °C. The predominant cellular fatty acids of strain BZ30T were summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) (37.4 %), C18 : 1 ω7c (19.6 %), C16 : 0 (8.2 %), C14 : 0 2-OH (8.0 %) and C16 : 0 2-OH (5.0 %). The predominant ubiquinone was Q-10. Major polar lipids were sphingoglycolipids, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. Spermidine was the major polyamine. The genomic DNA G+C content was 64.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain BZ30T belonged to the family Sphingomonadaceae of the α-4 group of the phylum Proteobacteria, and was related to the members of the genus Sphingopyxis, sharing the highest sequence similarities with the type strains of Sphingopyxis chilensis (98.3 %), S. witflariensis (98.2 %), S. taejonensis (97.4 %) and S. ginsengisoli (97.2 %). On the basis of the phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness data, strain BZ30T represents a novel species of the genus Sphingopyxis, for which the name Sphingopyxis bauzanensis is proposed. The type strain is BZ30T (=DSM 22271T =CGMCC 1.8959T =CIP 110136T).
