A Gram-positive, rod-shaped, non-spore-forming and strictly aerobic bacterium (Gsoil 161T) was isolated from soil of a ginseng field in Pocheon Province, South Korea. The novel isolate was characterized using a polyphasic approach in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 161T was shown to belong to the family Nocardioidaceae and was related to Aeromicrobium marinum (98.0 % similarity to the type strain), Aeromicrobium alkaliterrae (97.6 %), Aeromicrobium fastidiosum (97.0 %) and Aeromicrobium erythreum (96.7 %); the sequence similarity with other species within the family was less than 94.4 %. It was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and C16 : 0, 10-methyl C18 : 0 (tuberculostearic acid), C16 : 0 2-OH, 10-methyl C17 : 0 and 10-methyl-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 65.5 mol%. These chemotaxonomic properties and phenotypic characteristics support the affiliation of strain Gsoil 161T to the genus Aeromicrobium. Results of physiological and biochemical tests enabled strain Gsoil 161T to be differentiated genotypically and phenotypically from currently known Aeromicrobium species. Therefore, strain Gsoil 161T represents a novel species, for which the name Aeromicrobium panaciterrae sp. nov. is proposed. The type strain is strain Gsoil 161T (=KCTC 19131T=DSM 17939T=CCUG 52476T).

Two novel strains belonging to the phylum Bacteroidetes [formerly the Cytophaga–Flexibacter–Bacteroides (CFB) group], designated Gsoil 040T and Gsoil 052T, were isolated from the soil of a ginseng field in Pocheon province, South Korea. A polyphasic approach was used to characterize the taxonomic position of the novel strains. Both strains were Gram-negative, aerobic, non-motile, non-spore-forming and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel isolates belong to the genus Chitinophaga but are clearly separated from the recognized species of this genus; gene sequence similarities between the novel isolates and type strains of recognized species ranged from 91.2 to 96.5 %. One exception was found; strain Gsoil 052T and the type strain of Chitinophaga filiformis had a gene sequence similarity of 99.6 % but had a DNA–DNA relatedness value of 38 %. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; major fatty acids, iso-C15 : 0 and C16 : 1 ω5c; major hydroxy fatty acid, iso-C17 : 0 3-OH and major polyamine, homospermidine) supported the affiliation of both strains Gsoil 040T and Gsoil 052T to the genus Chitinophaga. The results of physiological and biochemical tests enabled the genotypic and phenotypic differentiation of the novel strains from the other recognized species of the genus Chitinophaga. Therefore, it is suggested that the new isolates represent two novel species, for which the names Chitinophaga ginsengisegetis sp. nov. [type strain Gsoil 040T (=KCTC 12654T=DSM 18108T)] and Chitinophaga ginsengisoli sp. nov. [type strain Gsoil 052T (=KCTC 12592T=DSM 18017T)] are proposed.

A novel Gram-stain-positive, motile, strictly aerobic bacterium, designated YIM 93174T, was isolated from a salt field in Korea. Cells of this strain were rod-shaped and formed pale tangerine colonies and grew at pH 6.0–8.0 (optimal growth at pH 7.0), at 15–45 °C (optimum 28–37 °C) and at salinities of 0–10 % (w/v) NaCl (optimum 0–2 % NaCl). Some phenotypic characters allowed differentiation of strain YIM 93174T from its nearest phylogenetic relatives. Comparative 16S rRNA gene sequence analysis showed that strain YIM 93174T belongs to the genus Bacillus, exhibiting the highest level of sequence similarity with the type strain of Bacillus humi (95.7 %), followed by those of Bacillus alkalitelluris (94.9 %) and Bacillus litoralis (94.5 %). The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0. The cell-wall peptidoglycan was of the A1γ type, containing meso-diaminopimelic acid as the diagnostic diamino acid. The genomic DNA G+C content was 36.9 mol% and the predominant respiratory quinone was MK-7. The major polar lipids of strain YIM 93174T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and two unknown phospholipids. On the basis of the evidence from this polyphasic study, strain YIM 93174T represents a novel species of the genus Bacillus, for which the name Bacillus luteolus sp. nov. is proposed, with YIM 93174T ( = DSM 22388T  = KCTC 13210T  = CCTCC AA 208068T) as the type strain.

A Gram-positive, aerobic, coccus-shaped, non-endospore-forming bacterium (Gsoil 633T) was isolated from soil from a ginseng field in Pocheon province in South Korea. The novel isolate was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarities, strain Gsoil 633T was shown to belong to the family Propionibacteriaceae. The closest phylogenetic relative was Microlunatus phosphovorus DSM 19555T, with 96.1 % sequence similarity; the sequence similarity to other members of the family was less than 95.4 %. The isolate was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 69.8 mol%. The morphological and chemotaxonomic properties of the isolate were consistent with those of M. phosphovorus, but the results of physiological and biochemical tests allowed the phenotypic differentiation of strain Gsoil 633T from this species. Therefore, strain Gsoil 633T represents a novel species, for which the name Microlunatus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 633T (=KCTC 13940T=DSM 17942T).

A Gram-positive, rod-shaped, non-spore-forming bacterium (Gsoil 346T) was isolated from the soil of a ginseng field in South Korea and was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequences, strain Gsoil 346T was shown to belong to the genus Nocardioides in the family Nocardioidaceae, with the most closely related species being Nocardioides aquiterrae GW-9T (96.6 % 16S rRNA gene sequence similarity); however, the strain clustered in a distinct branch of the phylogenetic tree with Nocardioides kongjuensis A2-4T (96.2 %), Nocardioides aromaticivorans H-1T (96.1 %), Nocardioides nitrophenolicus NSP41T (96.1 %) and Nocardioides simplex ATCC 15799T (95.9 %). Strain Gsoil 346T was characterized chemotaxonomically and found to have ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, phosphatidylinositol and phosphatidylglycerol as the major polar lipids, MK-8(H4) as the predominant menaquinone and iso-C16 : 0, C18 : 1 ω9c and C17 : 1 ω8c as the major fatty acids. The G+C content of the genomic DNA of the novel strain was 73.0 mol%. These chemotaxonomic properties supported the placement of strain Gsoil 346T in the genus Nocardioides. The results of physiological and biochemical tests, along with the phylogenetic analysis, allowed strain Gsoil 346T to be differentiated genotypically and phenotypically from recognized species of the genus Nocardioides. Therefore, strain Gsoil 346T represents a novel species, for which the name Nocardioides panacisoli sp. nov. is proposed, with Gsoil 346T (=KCTC 19470T=DSM 21348T) as the type strain.

A rod shaped, Gram-stain-negative, chemo-organotrophic, heterotrophic, strictly aerobic, non-gliding bacterium, designated strain PLRT, was isolated from faeces of the mollusc Aplysia punctata (Mollusca, Gastropoda) that had been fed with green algae belonging to the genus Ulva. The novel strain was able to degrade ulvan, a polysaccharide extracted from green algae (Chlorophyta, Ulvophyceae). The taxonomic position of strain PLRT was investigated by using a polyphasic approach. Strain PLRT was dark orange, oxidase-positive, catalase-positive and grew optimally at 25 °C, at pH 7.5 and in the presence of 2.5 % (w/v) NaCl with an oxidative metabolism using oxygen as the electron acceptor. Nitrate could not be used as the electron acceptor. Strain PLRT had a Chargaff’s coefficient (DNA G+C content) of 35.3 mol%. Phylogenetic analysis based on the sequence of the 16S rRNA gene placed the novel strain in the family Flavobacteriaceae (phylum ‘Bacteroidetes’), within a clade comprising Stenothermobacter spongiae, Nonlabens tegetincola, Sandarakinotalea sediminis, Persicivirga xylanidelens and Persicivirga dokdonensis. The closest neighbours of strain PLRT were P. xylanidelens and P. dokdonensis, sharing 95.2 and 95.5 % 16S rRNA gene sequence similarity, respectively. Phylogenetic inference and differential phenotypic characteristics demonstrated that strain PLRT represents a novel species of the genus Persicivirga, for which the name Persicivirga ulvanivorans sp. nov. is proposed. The type strain is PLRT ( = CIP 110082T = DSM 22727T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus Altererythrobacter (<95.7 % sequence similarity). On the basis of the evidence presented in this study, the novel species Altererythrobacter namhicola sp. nov. (type strain KYW48T  = KCTC 22736T  = JCM 16345T) and Altererythrobacter aestuarii sp. nov. (type strain KYW147T  = KCTC 22735T  = JCM 16339T) are proposed.
