Bacterium Strain

A Gram-stain-negative bacterium, strain 5410S-62T, was isolated from an air sample collected in Suwon, Republic of Korea. It was aerobic, motile, mesophilic and formed rod-shaped cells. Colonies on R2A agar were convex, circular and pale orange with entire margins. Growth occurred at pH 5–9 (optimally at pH 7) and at 10–40 °C (optimally at 28 °C). It did not grow in the presence of 1 % NaCl. Comparative analyses of 16S rRNA gene sequences demonstrated that the novel strain was closely related to members of the genus Noviherbaspirillum . Strain 5410S-62T showed the highest sequence similarity (98.2 %) to Glaciimonas singularis A2-57T. It also showed high 16S rRNA gene sequence similarity (98.1–95.6 %) to members of the genus Noviherbaspirillum (98.1 % to Noviherbaspirillum aurantiacum SUEMI08T, 97.8 % to Noviherbaspirillum soli SUEMI10T and Noviherbaspirillum canariense SUEMI03T, 97.6 % to Noviherbaspirillum psychrotolerans PB1T and 95.6 % to Noviherbaspirillum malthae CC-AFH3T). The strain contained summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), C16 : 0 and summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) as major fatty acids, Q-8 as the only ubiquinone and large amounts of phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. Strain 5410S-62T revealed less than 70 % DNA–DNA relatedness with the type strains of closely related species of the genera Noviherbaspirillum and Herbaspirillum and Glaciimonas singularis . Based on the physiological, biochemical and chemotaxonomic data obtained in this study, it is proposed that strain 5410S-62T represents a novel species, Noviherbaspirillum suwonense sp. nov., with 5410S-62T ( = KACC 16657T =  NBRC 108944T) as the type strain.

Wide Range

Members of the metabolically diverse order Nitrosomonadales inhabit a wide range of environments. Two strains affiliated with this order were isolated from soils in Germany and characterized by a polyphasic approach. Cells of strains 0125_3T and Swamp67T are Gram-negative rods, non-motile, non-spore-forming, non-capsulated and divide by binary fission. They tested catalase-negative, but positive for cytochrome c-oxidase. Both strains form small white colonies on agar plates and grow aerobically and chemoorganotrophically on SSE/HD 1 : 10 medium, preferably utilizing organic acids and proteinaceous substrates. Strains 0125_3T and Swamp67T are mesophilic and grow optimally without NaCl addition at slightly alkaline conditions. Major fatty acids are C16 : 1  ω7c, C16 : 0 and C14 : 0. The major polar lipids are diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyglycerol. The predominant respiratory quinone is Q-8. The G+C content for 0125_3T and Swamp67T was 67 and 66.1 %, respectively. The 16S rRNA gene analysis indicated that the closest relatives (<91 % sequence similarity) of strain 0125_3T were Nitrosospira multiformis ATCC 25196T, Methyloversatilis universalis FAM5T and Denitratisoma oestradiolicum AcBE2-1T, while Nitrosospira multiformis ATCC 25196T, Nitrosospira tenuis Nv1T and Nitrosospira lacus APG3T were closest to strain Swamp67T. The two novel strains shared 97.4 % 16S rRNA gene sequence similarity with one another and show low average nucleotide identity of their genomes (83.8 %). Based on the phenotypic, chemotaxonomic, genomic and phylogenetic analysis, we propose the two novel species Usitatibacter rugosus sp. nov (type strain 0125_3T=DSM 104443T=LMG 29998T=CECT 9241T) and Usitatibacter palustris sp. nov. (type strain Swamp67T=DSM 104440T=LMG 29997T=CECT 9242T) of the novel genus Usitatibacter gen. nov., within the novel family Usitatibacteraceae fam. nov.

Endophytic Actinobacterium

A novel endophytic actinobacterium, designated strain YIM 67072T, was isolated from healthy roots of Dysophylla stellata (Lour.) Benth. Cells of this aerobic, cream–yellow-coloured strain occurred singly, in pairs or in tetrads, were Gram-stain-positive and ovoid- to spherical-shaped. Strain YIM 67072T grew at 4–45 °C, pH 5.0–10.0 and in the presence of 0–7 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 67072T belonged to the genus Rothia . The isolate contained MK-7 as the major component of the quinone system. The peptidoglycan type was A3α. The polar lipid profile consisted predominantly of diphosphatidylglycerol and glycolipids. The major fatty acids were anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The DNA G+C content was 53.2 mol%. However, strain YIM 67072T differed from its closest relatives Rothia nasimurium CCUG 35957T (98.5 % 16S rRNA gene sequence similarity), Rothia amarae JCM 11375T (97.6 %) and Rothia terrae L-143T (97.3 %) in many phenotypic characteristics. Moreover, the levels of DNA–DNA relatedness between the novel isolate and the three above-mentioned type strains were 28.7±1.3 %, 36.5±1.2 %, 46.8±1.5 %, respectively. Based on comparative analysis of physiological and chemotaxonomic data, strain YIM 67072T represents a novel species of the genus Rothia , for which the name Rothia endophytica sp. nov. is proposed. The type strain is YIM 67072T ( = DSM 26247T = JCM 18541T).

Biochemical and molecular genetic studies were performed on four unknown Gram-stain-positive, catalase-negative, coccus-shaped organisms isolated from tonsils (n = 3) and nasal samples (n = 1) of four wild rabbits. The micro-organism was identified as a streptococcal species based on its cellular morphological and biochemical tests. Comparative 16S rRNA gene sequencing confirmed its identification as a member of the genus Streptococcus , but the organism did not correspond to any recognized species of this genus. The closest phylogenetic relative of the unknown cocci from wild rabbits was Streptococcus acidominimus NCIMB 702025T (97.9 % 16S rRNA gene sequence similarity). rpoB and sodA sequence analysis of the novel isolate showed interspecies divergence of 16.2 % and 20.3 %, respectively, from the type strain of its closest 16S rRNA gene phylogenetic relative, S. acidominimus . The novel bacterial isolate could be distinguished from the type strain of S. acidominimus by several biochemical characteristics, such as the production of esterase C4, acid phosphatase and naphthol-AS-BI-phosphohydrolase and acidification of different sugars. Based on both phenotypic and phylogenetic findings, it is proposed that the unknown bacterium be classified as a novel species of the genus Streptococcus , Streptococcus cuniculi sp. nov. The type strain is NED12-00049-6BT ( = CECT 8498T = CCUG 65085T).

Strain CH15-11T, isolated from a sediment sample taken from Daechung Reservoir, South Korea, during the late-blooming period of cyanobacteria, was found to be a Gram-stain-negative, non-motile, non-spore-forming, rod-shaped and aerobic bacterium. Strain CH15-11T grew optimally at pH 7 and 28–30 °C. According to a phylogenetic tree based on 16S rRNA gene sequences, strain CH15-11T belonged to the genus Sphingomonas and clustered with Sphingomonas sediminicola Dae 20T, with which it shared the highest 16S rRNA gene sequence similarity (97.6 %). Chemotaxonomic analysis showed that strain CH15-11T had characteristics typical of members of the genus Sphingomonas , such as the presence of sphingoglycolipid, ubiquinone Q-10 and sym-homospermidine. Plus, strain CH15-11T included summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0 as the major fatty acids. The genomic DNA G+C content was 65.6 mol%. Sequence data showed that strain CH15-11T was most closely related to Sphingomonas sediminicola Dae 20T (97.6 %), Sphingomonas ginsengisoli Gsoil 634T (97.2 %) and Sphingomonas jaspi TDMA-16T (97.0 %). However, the DNA–DNA relatedness values between strain CH15-11T and the most closely related type strains were within a range of 35–59 %. Thus, based on the phylogenetic, phenotypic and genetic data, strain CH15-11T was classified as a member of the genus Sphingomonas as a representative of a novel species, for which the name Sphingomonas daechungensis sp. nov. is proposed. The type strain is CH15-11T ( = KCTC 23718T = JCM 17887T).

Optimum Salinity

Strain LHWP2T, a novel, aerobic, budding, motile and ovoid bacterium belonging to the phylum Planctomycetes , was isolated from a dead ark clam (Scapharca broughtonii) from the south coast of Korea. Strain LHWP2T grew optimally at 30 °C, in the presence of 4 % (w/v) NaCl, and at pH 7. The predominant cellular fatty acids were C16 : 0, C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8) and C18 : 1ω9c. The major isoprenoid quinone was menaquinone-6 (MK-6). The dominant polar lipid was identified as phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain was most closely related to Blastopirellula marina DSM 3645T, with a 16S rRNA gene sequence similarity of 94.1 %. The genomic DNA G+C content of strain LHWP2T was 49.5 mol%. Strain LHWP2T was distinguished from B. marina DSM 3645T based on its optimum salinity, acid production from substrates, assimilation of substrates and DNA G+C content. Overall, these phenotypic, genotypic and phylogenetic data suggest that strain LHWP2T should be classified as a novel species belonging to the genus Blastopirellula , for which the name Blastopirellula cremea sp. nov. is proposed. The type strain is LHWP2T ( = KACC 15559T = JCM 17758T).

Marine Sand

A Gram-staining-negative, non-spore-forming, facultatively anaerobic, non-flagellated, non-gliding, rod-shaped bacterium, designated strain BR-18T, was isolated from marine sand collected on the western coast of South Korea. The taxonomic position of the novel strain was determined using a polyphasic approach. Strain BR-18T grew optimally at 25 °C, at pH 6.5–7.0 and in the absence of NaCl. In phylogenetic analyses based on 16S rRNA gene sequences, the novel strain fell within a clade comprising members of the genus Mucilaginibacter and appeared most closely related to Mucilaginibacter lutimaris BR-3T (96.6 % sequence similarity) and Mucilaginibacter rigui WPCB133T (95.9 %). The novel strain showed lower levels of 16S rRNA gene sequence similarity with the type strains of other members of the genus Mucilaginibacter (93.4–95.5 %) and those of other species included in the phylogenetic analyses (<91.6 %). Strain BR-18T contained MK-7 as its predominant menaquinone, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and iso-C15 : 0 as its major fatty acids, phosphatidylethanolamine and an unidentified aminophospholipid as its major polar lipids, and sphingolipids. The genomic DNA G+C content of the novel strain was 42.4 mol%. Based on the phylogenetic and phenotypic data, strain BR-18T represents a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter litoreus sp. nov. is proposed. The type strain is BR-18T ( = KCTC 23697T  = CCUG 61484T).

Strains LMG 27428T and LMG 27427 were isolated from the caecal content of a chicken and produced butyric, lactic and formic acids as major metabolic end products. The genomic DNA G+C contents of strains LMG 27428T and LMG 27427 were 40.4 and 38.8 mol%. On the basis of 16S rRNA gene sequence similarity, both strains were most closely related to the generically misclassified Streptococcus pleomorphus ATCC 29734T. Strain LMG 27428T could be distinguished from S. pleomorphus ATCC 29734T based on production of more lactic acid and less formic acid in M2GSC medium, a higher DNA G+C content and the absence of activities of acid phosphatase and leucine, arginine, leucyl glycine, pyroglutamic acid, glycine and histidine arylamidases, while strain LMG 27428 was biochemically indistinguishable from S. pleomorphus ATCC 29734T. The novel genus Faecalicoccus gen. nov. within the family Erysipelotrichaceae is proposed to accommodate strains LMG 27428T and LMG 27427. Strain LMG 27428T ( = DSM 26963T) is the type strain of Faecalicoccus acidiformans sp. nov., and strain LMG 27427 ( = DSM 26962) is a strain of Faecalicoccus pleomorphus comb. nov. (type strain LMG 17756T = ATCC 29734T = DSM 20574T). Furthermore, the nearest phylogenetic neighbours of the genus Faecalicoccus are the generically misclassified Eubacterium cylindroides DSM 3983T (94.4 % 16S rRNA gene sequence similarity to strain LMG 27428T) and Eubacterium biforme DSM 3989T (92.7 % 16S rRNA gene sequence similarity to strain LMG 27428T). We present genotypic and phenotypic data that allow the differentiation of each of these taxa and propose to reclassify these generically misnamed species of the genus Eubacterium formally as Faecalitalea cylindroides gen. nov., comb. nov. and Holdemanella biformis gen. nov., comb. nov., respectively. The type strain of Faecalitalea cylindroides is DSM 3983T = ATCC 27803T = JCM 10261T and that of Holdemanella biformis is DSM 3989T = ATCC 27806T = CCUG 28091T.

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, strain SC13E-S71T, was isolated from tuff, volcanic rock, where the Roman catacombs of Saint Callixtus in Rome, Italy, was excavated. Analysis of 16S rRNA gene sequences revealed that strain SC13E-S71T belongs to the genus Sphingopyxis , and that it shows the greatest sequence similarity with Sphingopyxis chilensis DSM 14889T (98.72 %), Sphingopyxis taejonensis DSM 15583T (98.65 %), Sphingopyxis ginsengisoli LMG 23390T (98.16 %), Sphingopyxis panaciterrae KCTC 12580T (98.09 %), Sphingopyxis alaskensis DSM 13593T (98.09 %), Sphingopyxis witflariensis DSM 14551T (98.09 %), Sphingopyxis bauzanensis DSM 22271T (98.02 %), Sphingopyxis granuli KCTC 12209T (97.73 %), Sphingopyxis macrogoltabida KACC 10927T (97.49 %), Sphingopyxis ummariensis DSM 24316T (97.37 %) and Sphingopyxis panaciterrulae KCTC 22112T (97.09 %). The predominant fatty acids were C18 : 1ω7c, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), C14 : 0 2-OH and C16 : 0. The predominant menaquinone was MK-10. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. These chemotaxonomic data are common to members of the genus Sphingopyxis . However, a polyphasic approach using physiological tests, DNA base ratios, DNA–DNA hybridization and 16S rRNA gene sequence comparisons showed that the isolate SC13E-S71T belongs to a novel species within the genus Sphingopyxis , for which the name Sphingopyxis italica sp. nov. is proposed. The type strain is SC13E-S71T ( = DSM 25229T = CECT 8016T).

A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529T, was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22–50 °C (optimum 28–45 °C), the pH range for growth was 6.0–8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0–7 % (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 1ω6c, iso-C16 : 1 H and C16 : 1ω7c/iso-C15 : 0 2-OH. The DNA G+C content of strain SCSIO 11529T was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529T belongs to the genus Prauserella , with the closest neighbours being Prauserella marina MS498T (97.0 % 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194T (96.4 %) and Prauserella flava YIM 90630T (95.9 %). Based on the evidence of the present study, strain SCSIO 11529T is considered to represent a novel species of the genus Prauserella , for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529T ( = DSM 45821T = NBRC 109418T).
