Two Gram-reaction-negative, rod-shaped, gliding, yellow-pigmented bacterial strains, designated ZLD-17T and ZLD-29T, were isolated from arid soil samples collected from Xinjiang Province, north-west China, and subjected to analysis using a polyphasic taxonomic approach. Both novel strains required 1.0–2.0 % (w/v) sea salts for optimal growth. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these two strains belong to the genus Lysobacter within the class Gammaproteobacteria. Strain ZLD-17T showed highest 16S rRNA gene sequence similarities to Lysobacter capsici KCTC 22007T (96.9 %), Lysobacter spongiicola DSM 21749T (96.8 %) and Lysobacter koreensis KCTC 12204T (96.8 %), whereas strain ZLD-29T showed highest sequence similarities to Lysobacter niastensis DSM 18481T (96.0 %) and Lysobacter enzymogenes DSM 2043T (95.9 %). 16S rRNA gene sequence similarity between ZLD-17T and ZLD-29T was 96.1 %. The DNA G+C contents of strains ZLD-17T and ZLD-29T were 67.9 and 68.2 mol%, respectively. The major cellular fatty acids of both strains were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C17 : 1ω9c, iso-C16 : 0, C16 : 0 and iso-C11 : 0 3-OH; their predominant isoprenoid quinone was Q-8 and their major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Based on their phenotypic characteristics, phylogenetic position as determined by 16S rRNA gene sequence analysis and chemotaxonomic data, strains ZLD-17T ( = CCTCC AB 207174T  = KCTC 23076T) and ZLD-29T ( = CCTCC AB 207175T = KCTC 23077T) represent two novel species of the genus Lysobacter, for which the names Lysobacter korlensis sp. nov. and Lysobacter bugurensis sp. nov. are proposed, respectively.

Strain B538T is a Gram-positive, motile, rod-shaped bacterium, which was isolated from Xinjiang province in China. This organism grew optimally at 30–35 °C and pH 8.0–8.5. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain B538T belonged to the genus Paenibacillus and chemotaxonomic data (DNA G+C content, 47.0 mol%; major isoprenoid quinone, MK-7; cell wall type, A1γ meso-diaminopimelic acid; major fatty acids, anteiso-C15 : 0 and C16 : 0) supported affiliation of the isolate with the genus Paenibacillus. Comparative 16S rRNA gene sequence analyses showed that the isolate was most closely related to Paenibacillus glycanilyticus DS-1T, with 16S rRNA gene sequence similarity of 98.1 %; sequence similarities to other members of the genus Paenibacillus used in the phylogenetic tree were less than 96.5 %. The DNA–DNA relatedness between strain B538T and P. glycanilyticus DS-1T was about 8.0 %. On the basis of physiological and molecular properties, strain B538T (=KCTC 3952T=DSM 16970T) is proposed as the type strain of a novel species within the genus Paenibacillus, for which the name Paenibacillus xinjiangensis sp. nov. is proposed.

Two Gram-negative, non-motile, pleomorphic bacterial strains, DS-40T and DS-45T, were isolated from a soil sample collected from Dokdo, Korea, and their exact taxonomic positions were investigated by using a polyphasic approach. Strains DS-40T and DS-45T grew optimally at 25 °C and pH 6.5–7.5 in the presence of 0–1.0 % (w/v) NaCl. They contained MK-7 as the predominant menaquinone and possessed iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C contents of strains DS-40T and DS-45T were 36.0 and 36.8 mol%, respectively. Strains DS-40T and DS-45T shared a 16S rRNA gene sequence similarity of 96.7 % and demonstrated a mean DNA–DNA relatedness level of 12 %. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains DS-40T and DS-45T were most closely phylogenetically affiliated with the genus Pedobacter of the family Sphingobacteriaceae. Strains DS-40T and DS-45T exhibited 16S rRNA gene sequence similarity values of 91.4–93.7 and 89.9–91.6 % with respect to the type strains of Pedobacter and Sphingobacterium species, respectively. Phenotypic and chemotaxonomic properties, together with the phylogenetic data, support the assignment of strains DS-40T and DS-45T as two distinct species within the genus Pedobacter. On the basis of phenotypic, phylogenetic and genetic data, strains DS-40T and DS-45T represent two novel species of the genus Pedobacter, for which the names Pedobacter lentus sp. nov. and Pedobacter terricola sp. nov. are proposed, respectively. The respective type strains are DS-40T (=KCTC 12875T=JCM 14593T) and DS-45T (=KCTC 12876T=JCM 14594T).

Limit-dilution procedures were used to isolate seven, helically coiled bacterial strains from faeces of swine that constituted two unidentified taxa. Comparative 16S rRNA gene sequence analysis showed highest similarity values with species of the genus Treponema indicating that the isolates are members of this genus. Strain 7CPL208T, as well as five further isolates, and 14V28T displayed the highest 16S rRNA gene sequence similarities with Treponema pectinovorum ATCC 33768T (92·3 %) and Treponema parvum OMZ 833T (89·9 %), respectively. Polar lipid profiles distinguished 7CPL208T and 14V28T from each other as well as from related species. Based on their phenotypic and genotypic distinctiveness, strains 7CPL208T and 14V28T are suggested to represent two novel species of the genus Treponema, for which the names Treponema berlinense sp. nov. and Treponema porcinum sp. nov. are proposed. The type strain for Treponema berlinense is 7CPL208T (=ATCC BAA-909T=CIP 108244T=JCM 12341T) and for Treponema porcinum 14V28T (=ATCC BAA-908T=CIP 108245T=JCM 12342T).

Bacterial Strains

Two bacterial strains (JC247T and JC248) were isolated from soil samples collected from Rann of Kutch, Gujarat, India. Colonies of both strains were creamy white. Cells were Gram-stain-positive, rods-to-curved rods (crescent-shaped), and produced centrally located oval-shaped endospores. Major (>5 %) fatty acids of both strains were iso-C16  :  0, iso-C14  :  0, iso-C15  :  0, C16  :  1ω11c and C16  :  0, with minor ( < 5 but >1 %) amounts of anteiso-C15  :  0, anteiso-C17  :  0, iso-C16  :  1 H, iso-C17  :  0, iso-C18  :  0, C14  :  0, C17  :  0, C18  :  0, C18  :  1ω9c, iso-C17  :  1ω10c and anteiso-C17  :  0B/isoI. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids of both strains. Cell-wall amino acids were l-alanine, d-alanine, d-glutamic acid and meso-diaminopimelic acid. The genomic DNA G+C content of strains JC247T and JC248 was 48.2 and 48.1 mol%, respectively. Both strains were closely related with mean DNA–DNA hybridization >90 %. 16S rRNA gene sequence analysis of both strains indicated that they are members of the genus Bacillus within the family Bacillaceae of the phylum Firmicutes. Both strains had a 16S rRNA gene sequence similarity of 96.93 % with Bacillus firmus NCIMB 9366T and < 96.92 % with other members of the genus Bacillus. Sequence similarity between strain JC247T and JC248 was 100 %. Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strains JC247T and JC248 as representatives of a novel species of the genus Bacillus, for which the name Bacillus crescens sp. nov. is proposed. The type strain is JC247T ( = KCTC 33627T = LMG 28608T).

The Family

A heterotrophic, Gram-negative, prosthecate bacterium, designated strain G5T, was isolated from a sandy beach of Taean in South Korea. Cells of strain G5T were aerobic, catalase- and oxidase-positive, straight to slightly curved motile rods with a single flagellum and formed yellow–orange colonies on agar. Growth occurred at 15–40 °C (optimum 25–30 °C) and pH 6–9 (optimum pH 7–8). The major cellular fatty acids were C18 : 1ω7c, C17 : 0, C16 : 0, 11-methyl C18 : 1ω7c, C17 : 1ω8c and C17 : 1ω6c. The polar lipid pattern indicated the presence of phosphatidylglycerol, monoglycosyldiglyceride, glucuronopyranosyldiglyceride and two unidentified glycolipids. The G+C content of the genomic DNA was 63.6 mol% and the major quinone was Q-10. Comparative 16S rRNA gene sequence analysis showed that strain G5T belonged to the branch containing the genera Hellea, Robiginitomaculum and Hypomonas within the family Hyphomonadaceae. Within this group, strain G5T was most closely related to Hellea balneolensis 26III/A02/215T with 95.8 % 16S rRNA gene sequence similarity. Based on its phylogenetic position and its phenotypic, chemotaxonomic and molecular properties, strain G5T represents a novel species of a novel genus of the family Hyphomonadaceae, for which the name Litorimonas taeanensis gen. nov., sp. nov. is proposed. The type strain is G5T ( = KACC 13701T  = DSM 22008T).

Respiratory Quinone

Two bacterial strains, PC-142 and PC-147T, isolated from poultry litter compost, were characterized with respect to their phenetic and phylogenetic characteristics. The isolates were endospore-forming rods that were reddish in colour after Gram staining. They were catalase- and oxidase-positive, were able to degrade starch and gelatin and grew at 15–40 °C and pH 5.5–10.0. The predominant fatty acids were anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0, the major respiratory quinone was menaquinone MK-7, the cell-wall peptidoglycan was of the A1γ type and the G+C content of the DNA was 58 mol%. The 16S rRNA gene sequence analysis and phenetic characterization indicated that these organisms belong to the genus Paenibacillus, with Paenibacillus pasadenensis SAFN-007T as the closest phylogenetic neighbour (97.5 %). Strains PC-142, PC-147T and P. pasadenensis SAFN-007T represent a novel lineage within the genus Paenibacillus, characterized by a high DNA G+C content (58–63 mol%). The low levels of 16S rRNA gene sequence similarity with respect to other taxa with validly published names and the identification of distinctive phenetic features in the two isolates indicate that strains PC-142 and PC-147T represent a novel species of the genus Paenibacillus, for which the name Paenibacillus humicus sp. nov. is proposed. The type strain is PC-147T (=DSM 18784T =NBRC 102415T =LMG 23886T).

A Gram-reaction-positive, non-motile, non-spore-forming, aerobic rod, designated BXN5-15T, was isolated from the soil of a ginseng field on Baekdu Mountain in China. Strain BXN5-15T grew optimally at 30 °C and pH 6.0–7.0 in the absence of NaCl on R2A agar. Strain BXN5-15T displayed β-glucosidase activity, which allowed it to transform ginsenoside Rb1 (one of the dominant active components of ginseng) via Rd to minor ginsenoside F2. On the basis of 16S rRNA gene sequence analysis, strain BXN5-15T was shown to belong to the genus Solirubrobacter. The closest phylogenetic relatives were Solirubrobacter soli Gsoil 355T (98.4 % 16S rRNA gene sequence similarity) and Solirubrobacter pauli B33D1T (96.4 %). Lower sequence similarities (<96.0 %) were found with all of the other recognized members of the order Solirubrobacterales. The predominant quinone was MK-7(H4). The major fatty acids (>10 %) were C18 : 1ω9c, iso-C16 : 0 and C18 : 3ω6,9,12c. The G+C content of the genomic DNA was 70.6 mol%. DNA−DNA relatedness between strain BXN5-15T and S. soli KCTC 12628T was 23.3 %. On the basis of genotypic, phenotypic and chemotaxonomic data, strain BXN5-15T represents a novel species within the genus Solirubrobacter, for which the name Solirubrobacter ginsenosidimutans sp. nov. is proposed. The type strain is BXN5-15T ( = KACC 20671T  = LMG 24459T).

Using a polyphasic taxonomic approach, we investigated three bacterial strains – IWT30T, IWT8 and IWT75 – isolated from total mixed ration silage prepared in Hachimantai, Iwate, Japan. The isolates comprised Gram-stain positive, non-motile, non-spore-forming, catalase-negative, rod-shaped bacteria. Good growth occurred at 15–45 °C and at pH 4.0–7.5. Their major cellular fatty acids were C18:1ω9c and C19:1 cyclo 9,10.The G+C content of genomic DNA of strain IWT30T was 44.6 mol%. Comparative 16S rRNA gene sequence analysis showed that these novel strains belonged to the genus Lactobacillus. These strains shared 100 % 16S rRNA gene sequence similarity and were most closely related to the type strains of Lactobacillus silagei, Lactobacillus odoratitofui, Lactobacillus similis, Lactobacillus collinoides, Lactobacillus paracollinoides and Lactobacillus kimchicus, with sequence similarity values of 99.5, 98.8, 98.7, 97.8, 97.8 and 96.8 %, respectively. The level of DNA–DNA relatedness between these strains and their closest phylogenetic neighbours was less than 30 %. On the basis of additional phylogenetic analysis of pheS and rpoA gene sequences and phenotypic and chemotaxonomic characteristics, we conclude that these three strains represent a novel species of the genus Lactobacillus, for which we propose the name Lactobacillus mixtipabuli sp. nov. The type strain is IWT30T ( = JCM 19805T = DSM 28580T).

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.

Phylogenetic Affiliation

Two Gram-negative, rod-shaped, oxidase-positive, non-spore-forming, non-motile bacteria (CCUG 46016T and CCUG 33852T), isolated from a knee aspirate of a 66-year-old man and an industrial glue, respectively, were studied for their taxonomic position. On the basis of chemotaxonomic data [i.e. major ubiquinone (Q-10), major polar lipids (phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine) and major fatty acids (C18 : 1 ω7c and C19 : 0 cyclo ω8c)] and 16S rRNA gene sequence similarity, both strains belong to the Alphaproteobacteria. The presence of spermidine and putrescine as the predominant polyamines in CCUG 46016T were in agreement with its phylogenetic affiliation in the vicinity of the genus Ochrobactrum. 16S rRNA gene sequence similarities between both strains and established species within the genera Bartonella, Ochrobactrum and Brucella were less than 95 %. Although both organisms showed highest 16S rRNA gene sequence similarity to members of Brucella, phenotypic features (including chemotaxonomic features) were more like those of members of the genus Ochrobactrum. Sequence comparison of the recA genes confirmed the separate phylogenetic position of the two strains. On the basis of DNA–DNA pairing results and physiological and biochemical data, the two strains can be clearly differentiated from each other and from all known Ochrobactrum species. It is evident that these organisms represent two novel species in a new genus, Pseudochrobactrum gen. nov., for which the names Pseudochrobactrum asaccharolyticum sp. nov. (the type species, type strain CCUG 46016T=CIP 108977T) and Pseudochrobactrum saccharolyticum sp. nov. (type strain CCUG 33852T=CIP 108976T) are proposed.
