A novel Gram-positive bacterium, strain 40T, was isolated in the course of identifying bacteria from infective juveniles of the entomopathogenic nematode Steinernema thermophilum. Based on 16S rRNA gene analysis, strain 40T was found to be related to the type strains of recognized species of the genus Leucobacter, family Microbacteriaceae. The 16S rRNA gene sequence similarity values of strain 40T and Leucobacter albus IAM 14851T, Leucobacter luti LMG 23118T, Leucobacter alluvii LMG 23117T, Leucobacter komagatae DSM 8803T, Leucobacter chromiireducens CIP 108389T and Leucobacter aridicollis CIP 108388T, respectively, were 97.3, 97.5, 97.6, 97.6, 97.6 and 98.5 %. Chemotaxonomic analysis also supported the affiliation of strain 40T to the genus Leucobacter: the major menaquinone was MK-11, the peptidoglycan cross-linkage was of the B-type, the cell wall diamino acid was l-diaminobutyric acid and the major fatty acids were anteiso-C15 : 0 (42 %), anteiso-C17 : 0 (34 %) and iso-C16 : 0 (16 %). Based upon the biochemical and genomic analyses, strain 40T is sufficiently distinct from the type strains of recognized Leucobacter species to warrant the description of a novel species, for which the name Leucobacter iarius sp. nov. is proposed. The type strain is strain 40T (=DSM 17402T=CIP 108831T).

A Gram-stain-positive, aerobic, rod-shaped, yellow actinobacterium, designated MNA2T, was isolated from a hexachlorocyclohexane-contaminated soil in North India. Strain MNA2T showed 95 % 16S rRNA gene sequence similarity with Microbacterium halotolerans YIM 70130T. Phylogenetic analysis of 16S rRNA gene sequences showed that strain MNA2T belonged to a clade represented by the genus Microbacterium of the family Microbacteriaceae. Strain MNA2T contained anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0 as the predominant fatty acids and diphosphatidylglycerol, phosphatidylglycerol and two unknown polar lipids. The menaquinones were MK-12, MK-11, MK-13 and MK-10, in an approximate molar ratio of 45 : 40 : 13 : 3, respectively. The DNA G+C content was 65.3 mol%. The peptidoglycan was of the B type of cross-linkage with ornithine as the diagnostic diamino acid. The results of the phylogenetic, phenotypic and chemotaxonomic analysis indicate that strain MNA2T belongs to a previously unrecognized species of the genus Microbacterium, for which the name Microbacterium lindanitolerans sp. nov. is proposed. The type strain is MNA2T (=DSM 22422T =CCM 7585T).

A Gram-variable, motile and rod-shaped bacterial strain, ASL-1T, was isolated from a marine saltern located on the coast of the Yellow Sea, Korea. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain ASL-1T clustered with Jeotgalibacillus alimentarius YKJ-13T and that this cluster joined the clade comprising the type strains of two Marinibacillus species. Strain ASL-1T exhibited 16S rRNA gene sequence similarity values of 97.3 % to J. alimentarius YKJ-13T and 96.5 % to the type strains of Marinibacillus marinus and Marinibacillus campisalis. The chemotaxonomic properties of strain ASL-1T were similar to those of one or two of the genera Jeotgalibacillus and Marinibacillus. The peptidoglycan type was A1α linked directly through l-lysine as the diamino acid. Strain ASL-1T contained MK-7 as the predominant menaquinone with the presence of a significant amount of MK-8. The predominant fatty acid was anteiso-C15 : 0. The DNA G+C content was 42.9 mol%. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain ASL-1T could be differentiated from J. alimentarius and the two Marinibacillus species. On the basis of the data presented, strain ASL-1T represents a novel species within the genus Jeotgalibacillus, for which the name Jeotgalibacillus salarius sp. nov. is proposed. The type strain is ASL-1T (=KCTC 13257T=CCUG 56751T). It is also proposed that Marinibacillus marinus and Marinibacillus campisalis be reclassified as Jeotgalibacillus marinus comb. nov. (type strain 581T=DSM 1297T=ATCC 29841T=CCUG 28884T=CIP 103308T=LMG 6930T) and Jeotgalibacillus campisalis comb. nov. (type strain SF-57T=KCCM 41644T=JCM 11810T), respectively.

A Gram-negative, non-motile, rod-shaped bacterium, strain ISL-6T, phenotypically resembling members of the genus Salegentibacter, was isolated from a marine solar saltern of the Yellow Sea in Korea and subjected to a polyphasic taxonomic investigation. Strain ISL-6T grew optimally at pH 7.0–8.0 and 30 °C and in the presence of 8 % (w/v) NaCl. It contained MK-6 as the predominant menaquinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The DNA G+C content was 37.5 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-6T belonged to the genus Salegentibacter. Strain ISL-6T exhibited 16S rRNA gene sequence similarity values of 92.0–98.6 % with respect to the type strains of recognized Salegentibacter species. Low DNA–DNA relatedness values, differential phenotypic properties and phylogenetic distinctiveness demonstrated that strain ISL-6T is distinguishable from the recognized Salegentibacter species. Therefore strain ISL-6T represents a novel species of the genus Salegentibacter, for which the name Salegentibacter salarius sp. nov. is proposed. The type strain is ISL-6T (=KCTC 12974T =CCUG 54355T).

A Gram-positive, aerobic or facultatively anaerobic, rod-shaped, spore-forming bacterium, strain Gsoil 1138T, was isolated from soil of a ginseng field in Pocheon Province, South Korea, and was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, strain Gsoil 1138T was shown to belong to the family Paenibacillaceae and was most closely related to the type strains of Paenibacillus chondroitinus (98.2 % similarity) and Paenibacillus alginolyticus (96.5 %). Levels of 16S rRNA gene sequence similarity between strain Gsoil 1138T and the type strains of other recognized species of the genus Paenibacillus were below 96.5 %. The G+C content of the genomic DNA of strain Gsoil 1138T was 52.1±0.2 mol% (mean±sd of three determinations). Phenotypic and chemotaxonomic data (MK-7 as the major menaquinone and anteiso-C15 : 0 and iso-C16 : 0 as the predominant fatty acids) supported the affiliation of strain Gsoil 1138T to the genus Paenibacillus. The results of DNA–DNA hybridization experiments and physiological and biochemical tests allowed strain Gsoil 1138T to be distinguished genotypically and phenotypically from recognized species of the genus Paenibacillus. Strain Gsoil 1138T is therefore considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus pocheonensis sp. nov. is proposed. The type strain is Gsoil 1138T (=KCTC 13941T=LMG 23404T).

A novel actinomycete, designated strain Sco-B14T, was isolated from volcanic ash collected near Darangshi Oreum (a parasitic or satellite volcano) in Jeju, Republic of Korea. The organism formed well-developed, branched substrate mycelium, on which short chains of non-motile spores were arranged singly or in clusters. Aerial mycelium was not produced. Globose bodies were observed. The reverse colour of colonies was light brown to brown. Diffusible pigments were produced on ISP medium 3 and oatmeal-nitrate agar. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Sco-B14T formed a lineage within the family Micromonosporaceae and was distinct from established genera. The 16S rRNA gene sequence similarity of strain Sco-B14T to members of related genera of the family was 95.0–95.7 % to type strains of Catellatospora species, 94.7 % to Hamadaea tsunoensis IMSNU 22005T, 94.7 % to Longispora albida K97-0003T and 94.0 % to Catelliglobosispora koreensis LM 042T. 3-Hydroxydiaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Whole-cell sugars were glucose, rhamnose, ribose, xylose, arabinose, galactose and mannose. The polar lipids included diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The menaquinone profile contained MK-10(H4) (49 %), MK-9(H4) (24 %), MK-10(H6) (18 %) and MK-9(H6) (9 %). The predominant fatty acids were iso-C15 : 0 and C17 : 0. The DNA G+C content was 70.1 mol%. The combination of chemotaxonomic and phylogenetic data clearly separated the isolate from the type strains of all genera in the family Micromonosporaceae. On the basis of the phylogenetic and chemotaxonomic data presented in this paper, strain Sco-B14T is considered to represent a novel species of a new genus in the family Micromonosporaceae, for which the name Allocatelliglobosispora scoriae gen. nov., sp. nov. is proposed. The type strain of Allocatelliglobosispora scoriae is Sco-B14T (=KCTC 19661T =DSM 45362T).

Two Gram-negative, motile, non-spore-forming and slightly halophilic rods (strains SW-145T and SW-156T) were isolated from sea water of the Yellow Sea in Korea. Strains SW-145T and SW-156T grew optimally at 37 and 30–37 °C, respectively, and in the presence of 2–6 % (w/v) NaCl. Strains SW-145T and SW-156T were chemotaxonomically characterized as having ubiquinone-9 as the predominant respiratory lipoquinone and C16 : 0, C18 : 1 ω9c, C16 : 1 ω9c and C12 : 0 3-OH as the major fatty acids. The DNA G+C contents of strains SW-145T and SW-156T were 58 and 57 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains SW-145T and SW-156T fell within the evolutionary radiation enclosed by the genus Marinobacter. The 16S rRNA gene sequences of strains SW-145T and SW-156T were 94·8 % similar. Strains SW-145T and SW-156T exhibited 16S rRNA gene sequence similarity levels of 94·3–98·1 and 95·4–97·7 %, respectively, with respect to the type strains of all Marinobacter species. Levels of DNA–DNA relatedness, together with 16S rRNA gene sequence similarity values, indicated that strains SW-145T and SW-156T are members of two species that are distinct from seven Marinobacter species with validly published names. On the basis of phenotypic properties and phylogenetic and genotypic distinctiveness, strains SW-145T (=KCTC 12185T=DSM 16070T) and SW-156T (=KCTC 12184T=DSM 16072T) should be placed in the genus Marinobacter as the type strains of two distinct novel species, for which the names Marinobacter flavimaris sp. nov. and Marinobacter daepoensis sp. nov. are proposed.
