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).

Two strains, designated B1-1T and B6-8T, were isolated from the Geumho River and the Dalseo Stream in Korea. Comparative 16S rRNA gene sequence analysis showed a clear affiliation of these two bacteria with the class Alphaproteobacteria, their closest relatives being Kaistia adipata KCTC 12095T, Kaistia granuli KCTC 12575T, Kaistia soli KACC 12605T and Kaistia terrae KACC 12910T with 16S rRNA gene sequence similarities of 95.3 –97.7 % to the two novel strains. Strains B1-1T and B6-8T shared a 16S rRNA gene sequence similarity value of 96.1 %. Cells of the two strains were Gram-reaction-negative, aerobic, non-motile, short rods or cocci. The predominant ubiquinone was Q-10. The major fatty acids were C16 : 0, C18 : 1ω7c, C18 : 0 and C19 : 0ω8c cyclo for strain B1-1T and C16 : 0, C18 : 1ω7c, C18 : 0, C18 : 1 2-OH, and C19 : 0ω8c cyclo for strain B6-8T. The G+C contents of the genomic DNA of the strains B1-1T and B6-8T were 61.6 and 66.5 mol%, respectively. Based on the results of this polyphasic study, strains B1-1T ( = KCTC 12849T  = DSM 18799T) and B6-8T ( = KCTC 12850T  = DSM 18800T) represent two novel species of the genus Kaistia, for which the names Kaistia geumhonensis sp. nov. and Kaistia dalseonensis sp. nov. are proposed, respectively.

Three Gram-negative, anaerobic, rod-shaped bacteria (strains CB40, CB41 and CB42T) were isolated from human faeces. Based on phylogenetic analysis and specific phenotypic characteristics, these strains were included in the genus Bacteroides, and 16S rRNA gene sequence analysis indicated that these strains represented a novel species. The strains were most closely related to the type strains of Bacteroides barnesiae and Bacteroides salanitronis, with sequence similarities of 93.4 and 89.8 %, respectively. The G+C content of strain CB42T is 44.7 mol%. Major fatty acids were anteiso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH and C18 : 1 ω9c. On the basis of the data presented, a novel Bacteroides species, Bacteroides coprophilus sp. nov., is proposed, with CB42T (=JCM 13818T=DSM 18228T) as the type strain.

Abstract A novel bacterium of the Streptomyces genus, designated TRM S81-3T, was isolated from soil in cotton fields of Xinjiang, China. Comparative 16S rRNA gene sequence analysis indicated that strain TRM S81-3T ismost closely related to Streptomyces naganishii NBRC 12892T (98.96% sequence similarity); however, the average nucleotide identity (ANI) between strains TRM S81-3T and S. naganishii NBRC 12892T is relatively low (86.26%). Strain TRM S81-3T possesses LL-diaminopimelic acid as the diagnostic cell-wall diamino acid, MK-9(H4), MK-9(H6), and MK-9(H10) as the major menaquinones, and polar lipids including DPG, PE, PC, PI, PME, NPG and PL. The major fatty acids are iso-C16:0, anteiso-C15:0, anteiso-C17:1 ω9c, anteiso-C17:0, iso-C15:0, and C14:0. The genomic DNA G+C content is 72.1%. Based on the evidence from this polyphasic study, strain TRM S81-3T represents a novel species of Streptomyces, for which the name Streptomyces grisecoloratus is proposed. The type strain is TRM S81-3T (=CCTCC AA 2020002T=LMG 31942T).

A Gram-negative, non-sporulating, non-flagellated rod, designated BR-9T, was isolated from soil collected on the Korean peninsula. Strain BR-9T grew optimally at pH 6.0–7.0, at 30 °C and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BR-9T belonged to the genus Pedobacter and clustered with Pedobacter insulae DS-139T and Pedobacter koreensis WPCB189T. Strain BR-9T exhibited 98.2 and 97.5 % 16S rRNA gene sequence similarity with P. insulae DS-139T and P. koreensis WPCB189T, respectively, and <96.7 % sequence similarity with the type strains of other species in the genus Pedobacter. Strain BR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C content of strain BR-9T was 38.5 mol%. DNA–DNA relatedness between strain BR-9T and P. insulae DS-139T and P. koreensis KCTC 12536T was 3.4–4.2 %, which indicated that the isolate was genetically distinct from these type strains. Strain BR-9T was also distinguishable by differences in phenotypic properties. On the basis of the data presented, strain BR-9T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter boryungensis sp. nov. is proposed. The type strain is BR-9T ( = KCTC 23344T  = CCUG 60024T).

A Gram-negative, rod-shaped, Flavobacterium-like bacterial strain, DS-20T, was isolated from soil from the island of Dokdo, Korea, and subjected to a polyphasic taxonomic study. Strain DS-20T grew optimally at pH 6.5–7.0 and 25 °C. It contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C17 : 0 3-OH and iso-C17 : 1 ω9c as the major fatty acids. The DNA G+C content was 38.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-20T belonged to the genus Flavobacterium. Levels of 16S rRNA gene sequence similarity between strain DS-20T and the type strains of recognized Flavobacterium species were below 94.9 %. Strain DS-20T differed from phylogenetically related Flavobacterium species in several phenotypic characteristics. On the basis of its phenotypic and phylogenetic distinctiveness, strain DS-20T was classified in the genus Flavobacterium as representing a novel species, for which the name Flavobacterium terrigena sp. nov. is proposed. The type strain is DS-20T (=KCTC 12761T=DSM 17934T).

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).

A Gram-stain-negative, yellow-pigmented bacterial strain, designated PR1012KT, was isolated from a motor car evaporator core collected in Korea. Cells of the strain were facultatively anaerobic, non-spore-forming and rod-shaped. The strain grew at 10–40 °C (optimum, 25 °C), at pH 6.5–8.0 (optimum, pH 7.0–8.0) and in the presence of 0–1 % (w/v) NaCl. Phylogenetically, the strain was closely related to members of the genus Spirosoma (97.50–90.74 % 16S rRNA gene sequence similarities) and showed highest sequence similarity to Spirosoma panaciterrae DSM 21099T (97.50 %). Its predominant fatty acids included summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 1ω5c, iso-C15 : 0 and summed feature 4 (iso-C17 : 1 I and/or anteiso B) and it had MK-7 as the major menaquinone. The polar lipids present included phosphatidylethanolamine, one unknown aminophospholipid, two unknown aminolipids and five unknown polar lipids. The DNA G+C content of this strain was 54 mol%. Based on phenotypic, genotypic and chemotaxonomic data, strain PR1012KT represents a novel species in the genus Spirosoma, for which the name Spirosoma aerolatum sp. nov. is proposed. The type strain is PR1012KT ( = KACC 17939T = NBRC 110794T).

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

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).
