A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

Gene Sequence Analysis

The phenotypic and phylogenetic characteristics of an aerobic, Gram-negative, motile, non-pigmented Alteromonas-like bacterium (designated strain KMM 3894T), isolated from a sandy sediment sample collected offshore of the Sea of Japan, were investigated. Comparative 16S rRNA gene sequence analysis revealed that strain KMM 3894T belonged to the genus Aestuariibacter and was most closely related to Aestuariibacter halophilus JC2043T (95.5 % sequence similarity). Fatty acid analysis showed C16 : 1 ω7c, C18 : 1 ω7c, and C16 : 0 as the dominant components. Strain KMM 3894T could be differentiated from recognized species of the genus Aestuariibacter by its ability to grow at 4 °C and at 30 °C, the optimum temperature for growth, and its inability to utilize most carbohydrates. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain KMM 3894T is considered to represent a novel species of the genus Aestuariibacter, for which the name Aestuariibacter litoralis sp. nov. is proposed. The type strain is KMM 3894T (=NRIC 0754T=JCM 15896T).

Taxonomic Approach

Identification of a bacterial strain, designated CJ71T, was carried out using a polyphasic taxonomic approach. Strain CJ71T was isolated from sediment from the estuarine wetland of the Han River, South Korea, by enrichment culture using pyrene as the sole carbon and energy source. The isolate was white-pigmented, rod-shaped, Gram-positive, strictly aerobic and motile. 16S rRNA gene sequence analysis revealed that strain CJ71T had the highest sequence similarity (96.9 %) to Brevibacillus formosus DSM 9885T. The predominant cellular fatty acids in strain CJ71T were anteiso-C15 : 0 (49.5 %), iso-C15 : 0 (16.9 %), iso-C14 : 0 (16.9 %) and iso-C16 : 0 (4.9 %). The major isoprenoid quinone was MK-7. The G+C content of the genomic DNA was 52.4 mol%. Results from the polyphasic taxonomic study suggest that strain CJ71T represents a novel species of the genus Brevibacillus for which the name Brevibacillus fluminis sp. nov. is proposed; the type strain is CJ71T (=KACC 13381T=JCM 15716T)

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.

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 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 yellow-pigmented, Gram-negative and aerobic bacterial strain, designated AT1026T, was isolated from a terrestrial sample from the Antarctic. Results of 16S rRNA gene sequence analysis indicated that the Antarctic isolate belonged to the genus Flavobacterium, with the highest sequence similarity to Flavobacterium tegetincola (96·4 %). Cells were non-motile, non-gliding and psychrotolerant, with optimum and maximum temperatures of about 20 and 25 °C. Flexirubins were absent. The major isoprenoid quinone (MK-6), predominant cellular fatty acids (iso-C15 : 1 G, iso-C15 : 0 and a mixture of C16 : 1 ω7c and/or iso-C15 : 0 2-OH) and DNA G+C content (38 mol%) of the Antarctic isolate were consistent with those of the genus Flavobacterium. In contrast, several phenotypic characters can be used to differentiate this isolate from other flavobacteria. The polyphasic data presented in this study indicated that this isolate should be classified as a novel species in the genus Flavobacterium. The name Flavobacterium antarcticum sp. nov. is therefore proposed for the Antarctic isolate; the type strain is AT1026T (=IMSNU 14042T=KCTC 12222T=JCM 12383T).

A Gram-negative, rod-shaped, motile bacterium was isolated from the soil of a ginseng field in Daejeon, South Korea, and characterized in order to determine its taxonomic position. Phylogenetic analysis based on 16S rRNA gene sequence analysis revealed that strain DCY34T belonged to the family Sphingomonadaceae, and the highest degree of sequence similarity was found with Sphingopyxis witflariensis W-50T (97.1 %), Sphingopyxis ginsengisoli Gsoil 250T (97.0 %), Sphingopyxis chilensis S37T (96.9 %), Sphingopyxis macrogoltabida IFO 15033T (96.8 %), Sphingopyxis alaskensis RB2256T (96.7 %) and Sphingopyxis taejonensis JSS54T (96.7 %). Chemotaxonomic data revealed that strain DCY34T possessed ubiquinone Q-10 as the predominant respiratory lipoquinone, which is common to members of the genus Sphingopyxis. The predominant fatty acids were C18 : 1 ω7c (27.5 %), summed feature 4 (C16 : 1 ω7c and/or C15 : 0 iso 2-OH; 18.6 %), C16 : 0 (15.6 %) and summed feature 8 (C19 : 1 ω6c and/or unknown 18.864; 15.4 %). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid and an unknown polar lipid. The results of physiological and biochemical tests clearly demonstrated that strain DCY34T represented a separate species and supported its affiliation to the genus Sphingopyxis. Based on these data, the new isolate represents a novel species, for which the name Sphingopyxis panaciterrulae sp. nov. is proposed. The type strain is DCY34T (=KCTC 22112T=JCM 14844T).

A Gram-positive, non-motile, endospore-forming bacterium, designated Gsoil 1517T, was isolated from soil of a ginseng field in Pocheon Province (South Korea) and was characterized in order to determine its taxonomic position, using a polyphasic approach. It was found to rod-shaped and aerobic or facultatively anaerobic. It grew optimally at 30 °C and at pH 6.5–7.0. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 1517T forms a distinct phylogenetic lineage within the genus Bacillus, being related to Bacillus funiculus JCM 11201T (96.8 %). The strain showed less than 94.3 % sequence similarity with other Bacillus species. The G+C content of the genomic DNA was found to be 47.8 mol% and the predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0 (42.4 %), anteiso-C15 : 0 (17.4 %), iso-C14 : 0 (9.7 %) and C16 : 0 (6.0 %). On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1517T represents a novel species of the genus Bacillus, for which the name Bacillus panaciterrae sp. nov. is proposed. The type strain is Gsoil 1517T (=KCTC 13929T=CCUG 52470T=LMG 23408T).
