Strain BL06T was isolated from landfill soil in Pohang, Korea. Strain BL06T is Gram-negative, aerobic, non-motile and rod-shaped. For growth, the NaCl range is 0–6 % (w/v), the temperature range is 10–44 °C and the pH range is 5.5–12.0. Based on the 16S rRNA gene and gyrase B (gyrB) gene sequences, phylogenetic analysis showed that strain BL06T is associated with the genus Alishewanella and related closely to the type strains of Alishewanella species (98.8 % 16S rRNA gene sequence similarity to Alishewanella aestuarii, 98.7 % to Alishewanella fetalis and 98.5 % to Alishewanella jeotgali). Physiological and biochemical tests verified that strain BL06T is genotypically and phenotypically different from previously described species in the genus Alishewanella. DNA–DNA hybridization experiments showed that relatedness between the genomic DNA of strain BL06T and type strains of other Alishewanella species is <41 %. These findings suggest strongly that the strain represents a novel species, despite high 16S rRNA gene sequence similarity between strain BL06T and related strains. Therefore, strain BL06T (=KCTC 22400T=JCM 15597T) is proposed to represent a novel species in the genus Alishewanella, named Alishewanella agri sp. nov.

A Gram-negative, aerobic or facultatively anaerobic, non-spore-forming, motile, rod-shaped bacterium (strain Gsoil 3165T) was isolated from soil of a ginseng field in Pocheon, South Korea. Its taxonomic position was determined by using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain Gsoil 3165T was shown to belong to the family Comamonadaceae, class Betaproteobacteria, and was related most closely to the type strains of Variovorax boronicumulans (98.9 % similarity), Variovorax paradoxus (98.3 %), Variovorax soli (98.2 %) and Variovorax dokdonensis (96.6 %). Levels of 16S rRNA gene sequence similarity between strain Gsoil 3165T and the type strains of other species in the family Comamonadaceae were less than 97.0 %. The G+C content of the genomic DNA of strain Gsoil 3165T was 66 mol%. Phenotypic and chemotaxonomic data (Q-8 as the major ubiquinone; C16 : 0 and C17 : 0 cyclo as major fatty acids) supported the affiliation of strain Gsoil 3165T to the genus Variovorax. The results of physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain Gsoil 3165T from recognized Variovorax species. Gsoil 3165T is therefore considered to represent a novel species of the genus Variovorax, for which the name Variovorax ginsengisoli sp. nov. is proposed. The type strain is Gsoil 3165T (=KCTC 12583T =LMG 23392T).

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).

Gene Sequence Analysis

A Gram-negative, rod-shaped, non-spore-forming bacterium was isolated from a nitrifying inoculum. On the basis of 16S rRNA gene sequence similarity, LMG 22862T was shown to belong to the family Sphingobacteriaceae, related to Pedobacter africanus (98·0 %) and Pedobacter heparinus (97·6 %). The results of 16S rRNA gene sequence analysis, DNA–DNA hybridization, SDS-PAGE, analysis of the fatty acid composition and physiological and biochemical tests allowed genotypic and phenotypic differentiation of LMG 22862T from Pedobacter species with validly published names. LMG 22862T therefore represents a novel species within this genus, for which the name Pedobacter caeni sp. nov. is proposed, with the type strain LMG 22862T (=DSM 16990T).

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).

Established Species

Two Gram-stain-positive bacterial isolates, strain 2385/12T and strain 2673/12T were isolated from a tapir and a dog's nose, respectively. The two strains were rod to coccoid-shaped, catalase-positive and oxidase-negative. The highest 16S rRNA gene sequence similarity identified Corynebacterium singulare CCUG 37330T (96.3 % similarity) as the nearest relative of strain 2385/12T and suggested the isolate represented a novel species. Corynebacterium humireducens DSM 45392T (98.7 % 16S rRNA gene sequence similarity) was identified as the nearest relative of strain 2673/12T. Results from DNA–DNA hybridization with the type strain of C. humireducens demonstrated that strain 2673/12T also represented a novel species. Strain 2385/12T showed a quinone system consisting predominantly of menaquinones MK-8(H2) and MK-9(H2) whereas strain 2673/12T contained only MK-8(H2) as predominant quinone. The polar lipid profiles of the two strains showed the major compounds phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. Phosphatidylinositol was identified as another major lipid in 2673/12T whereas it was only found in moderate amounts in strain 2385/12T. Furthermore, moderate to minor amounts of phosphatidylinositol-mannoside, β-gentiobiosyl diacylglycerol and variable counts of several unidentified lipids were detected in the two strains. Both strains contained corynemycolic acids. The polyamine patterns were characterized by the major compound putrescine in strain 2385/12T and spermidine in strain 2673/12T. In the fatty acid profiles, predominantly C18 : 1ω9c and C16 : 0 were detected. The two strains are distinguishable from each other and the nearest related established species of the genus Corynebacterium phylogenetically and phenotypically. In conclusion, two novel species of the genus Corynebacterium are proposed, namely Corynebacterium tapiri sp. nov. (type strain, 2385/12T = CCUG 65456T = LMG 28165T) and Corynebacterium nasicanis sp. nov. (type strain, 2673/12T = CCUG 65455T = LMG 28166T).

Separate Species

Two strains (Gsoil 492T and Gsoil 643T) isolated in Pocheon Province, South Korea, from soil used for ginseng cultivation were characterized using a polyphasic approach. Both isolates comprised Gram-negative, aerobic, non-motile, rod-shaped bacteria. They had similar chemotaxonomic characteristics, e.g. containing MK-7 as the major quinone, having a DNA G+C content in the range 42.5–43.3 mol% and possessing iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. A phylogenetic analysis based on 16S rRNA gene sequences indicated that the two isolates formed a tight cluster with several uncultured bacterial clones and with the established genera Terrimonas, Niastella and Chitinophaga in the phylum Bacteroidetes but were clearly separate from these genera. The levels of 16S rRNA gene sequence similarity between the isolates and type strains of related genera ranged from 87.5 to 92.4 %. Furthermore, the results of physiological and biochemical tests allowed phenotypic differentiation of the isolates from phylogenetically closely related species with validly published names. The level of 16S rRNA gene sequence similarity between the two strains was 99.5 %, whereas the DNA–DNA relatedness value was 44 %, indicating that they represent separate species. On the basis of the polyphasic evidence, a novel genus, Flavisolibacter gen. nov., and two novel species, Flavisolibacter ginsengiterrae sp. nov. (type strain Gsoil 492T=KCTC 12656T=DSM 18136T) and Flavisolibacter ginsengisoli sp. nov. (type strain Gsoil 643T=KCTC 12657T=DSM 18119T), are proposed. Flavisolibacter ginsengiterrae is the type species of the genus.

A Gram-positive, aerobic, long-rod-shaped, non-spore-forming bacterium (strain PPLBT) was isolated from soil mixed with Iberian pig hair. This actinomycete showed keratinase activity in vitro when chicken feathers were added to the culture medium. Strain PPLBT was oxidase-negative and catalase-positive and produced lipase and esterase lipase. This actinomycete grew at 40 °C on nutrient agar and in the same medium containing 5 % (w/v) NaCl. Growth was observed with many different carbohydrates as the sole carbon source. On the basis of 16S rRNA gene sequence similarity, strain PPLBT was shown to belong to the genus Terrabacter of the family Intrasporangiaceae. Strain PPLBT showed 98·8 % 16S rRNA gene sequence similarity to Terrabacter tumescens. Chemotaxonomic data, such as the main ubiquinone (MK-8), the main polar lipids (phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol) and the main fatty acids (i-C15 : 0, ai-C15 : 0, i-C16 : 0 and ai-C17 : 0) supported the affiliation of strain PPLBT to the genus Terrabacter. The G+C content of the DNA was 71 mol%. The results of DNA–DNA hybridization (36·6 % relatedness between Terrabacter tumescens and strain PPLBT) and physiological and biochemical tests suggested that strain PPLBT belongs to a novel species of the genus Terrabacter, for which the name Terrabacter terrae sp. nov. is proposed. The type strain is PPLBT (=CECT 3379T=LMG 22921T).

A Gram-negative, rod-shaped bacterium, IG8T, was isolated from seawater off the Sanriku coast, Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IG8T represented a separate lineage within the genus Loktanella; the highest 16S rRNA gene sequence similarity values were found with the type strains of Loktanella salsilacus (98.6 %) and Loktanella fryxellensis (98.4 %). DNA–DNA hybridization values between strain IG8T and the type strains of L. salsilacus (27.9–36.1 %) and L. fryxellensis (11.3–31.0 %) were clearly below 70 %, the generally accepted limit for species delineation. The DNA G+C content of strain IG8T was 66.3 mol%. On the basis of DNA–DNA hybridization, some biochemical characteristics and 16S rRNA gene sequence comparison, it is proposed that the isolate represents a novel species, Loktanella atrilutea sp. nov. The type strain is IG8T (=IAM 15450T=NCIMB 14280T).
