An orange-pigmented, Gram-staining-negative, rod-shaped bacterium, designated 96_Hippo_TS_3/13T was isolated from the brood pouch of a diseased seahorse male of the species Hippocampus barbouri from the animal facility of the University of Giessen, Germany. Phylogenetic analyses based on the nearly full-length 16S rRNA gene sequence placed strain 96_Hippo_TS_3/13T into the monophyletic cluster of the genus Mesonia within the family Flavobacteriaceae. However, the strain shared only 92.2–93.8 % sequence similarity to type strains of species of the genus Mesonia, with highest sequence similarity to the type strain of Mesonia aquimarina. Cellular fatty acid analysis showed a Mesonia-typical fatty acid profile including several branched and hydroxyl fatty acids with highest amounts of iso-C15 : 0 (40.9 %) followed by iso-C17 : 0 3-OH (14.8 %). In the polyamine pattern, sym-homospermidine was predominant. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The quinone system contained exclusively menaquinone MK-6. The only identified compound in the polar lipid profile was phosphatidylethanolamine present in major amounts. Additionally, major amounts of an unidentified aminolipid and two unidentified lipids not containing a phosphate group, an amino group or a sugar residue were detected. The genomic G+C content of strain 96_Hippo_TS_3/13T was 30 mol%. Based on genotypic, chemotaxonomic and physiological characterizations we propose a novel species of the genus Mesonia, Mesonia hippocampi sp. nov., with strain 96_Hippo_TS_3/13T ( = CIP 110839T =  LMG 28572T = CCM 8557T) as the type strain. An emended description of the genus Mesonia is also provided.

Phosphatidylinositol Mannosides

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

Taxonomical Study

Three short spore chain-forming actinomycete strains were isolated from soil samples collected from subtropical islands in Japan. The cell-wall peptidoglycan of these strains contained meso-diaminopimelic acid (meso-A2pm), glutamic acid and alanine. The major isoprenoid quinone was MK-9(H4), iso-C16 : 0 and 2-OH iso-C16 : 0 were the major cellular fatty acids and phosphatidylethanolamine was a component of the polar lipids. The G+C content of the genomic DNA was 67–69 mol%. Phylogenetic analyses based on the 16S rRNA gene sequences showed that the novel strains consistently formed a monophyletic cluster with Amycolatopsis taiwanensis. On the basis this polyphasic taxonomical study, it is proposed that the two new isolates represent two novel species: Amycolatopsis helveola (type strain TT00-43T=NBRC 103394T=KCTC 19329T) and Amycolatopsis pigmentata (type strain TT99-32T=NBRC 103392T=KCTC 19330T).

A novel filamentous bacterium, designated Nari11AT, was isolated from soil collected from a salt lake named Chott Melghir, located in north-eastern Algeria. The strain is an aerobic, halophilic, thermotolerant, Gram-stain-positive bacterium, growing at NaCl concentrations between 5 and 20 % (w/v) and at 43–60 °C and pH 5.0–10.0. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C17 : 0. The DNA G+C content was 53.4 mol%. ll-Diaminopimelic acid was the diamino acid of the peptidoglycan. The major menaquinone was MK-7, but MK-6 and MK-8 were also present in trace amounts. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and three unidentified phospholipids. Results of molecular and phenotypic analyses led to the description of the strain as a novel member to the genus Melghirimyces , family Thermoactinomycetaceae . Strain Nari11AT shows 96.7 % 16S rRNA gene sequence similarity to the type strain of Melghirimyces algeriensis . On the basis of phenotypic, physiological and phylogenetic data, strain Nari11AT ( = DSM 45514T  = CCUG 60050T) represents the type strain of a novel species, for which the name Melghirimyces thermohalophilus sp. nov. is proposed.

A Gram-variable, motile, endospore-forming, slightly halophilic bacterial strain, DSW-10T, was isolated from Dokdo, an island located at the edge of the East Sea, Korea, and was characterized taxonomically by using a polyphasic approach. This isolate grew optimally at 37 °C and in the presence of 4–5 % NaCl. Strain DSW-10T had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-7 as the predominant menaquinone, and anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and unidentified phospholipids. The DNA G+C content was 36·7 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DSW-10T is phylogenetically affiliated to the genus Virgibacillus, and exhibited sequence similarity of 95·3–98·7 % to the type strains of Virgibacillus species. DNA–DNA relatedness levels between strain DSW-10T and the type strains of some phylogenetically related Virgibacillus species were in the range 8·4–17·5 %. On the basis of phenotypic properties and phylogenetic and genetic distinctiveness, strain DSW-10T (=KCTC 3933T=DSM 16826T) was classified as the type strain of a novel Virgibacillus species, for which the name Virgibacillus dokdonensis sp. nov. is proposed.

The actinomycetes strains KRD168T and KRD185T were isolated from sediments collected from the deep Southern Ocean and, in this work, they are described as representing two novel species of the genus Pseudonocardia through a polyphasic approach. Despite sharing >99 % 16S rRNA gene sequence similarity with other members of the genus, comparative genomic analysis allowed species delimitation based on average nucleotide identity and digital DNA–DNA hybridization. The KRD168T genome is characterized by a size of 6.31 Mbp and a G+C content of 73.44 mol%, while the KRD185T genome has a size of 6.82 Mbp and a G+C content of 73.98 mol%. Both strains contain meso-diaminopimelic acid as the diagnostic diamino acid, glucose as the major whole-cell sugar, MK-8(H4) as a major menaquinone and iso-branched hexadecanoic acid as a major fatty acid. Biochemical and fatty acid analyses also revealed differences between these strains and their phylogenetic neighbours, supporting their status as distinct species. The names Pseudonocardia abyssalis sp. nov. (type strain KRD168T=DSM 111918T=NCIMB 15270T) and Pseudonocardia oceani (type strain KRD185T=DSM 111919T=NCIMB 15269T) are proposed.

A novel actinomycete strain, designated CS5-AC15T, was isolated from a soil sample collected from a cliff on Mara Island, Jeju, Republic of Korea, and subjected to a polyphasic taxonomic analysis. The isolate produced well-developed, yellow substrate mycelium and white aerial mycelium that differentiated into straight or flexuous chains of smooth-surfaced spores. 16S rRNA gene sequence analyses showed that the organism belonged to the family Thermomonosporaceae and formed a tight cluster with the type strain of Actinomadura oligospora (97.4 % sequence similarity). Chemotaxonomic characteristics were consistent with its assignment to the genus Actinomadura in that the isolate had meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall, madurose as the characteristic sugar, N-acetyl type of murein in the peptidoglycan, MK-9(H6) and MK-9(H8) as major menaquinones and a polar lipid profile containing diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown phospholipids. Mycolic acids were not detected. The predominant fatty acids were C16 : 0, C18 : 1ω9c and iso-C16 : 0. The DNA G+C content was 70.9 mol%. DNA relatedness of strain CS5-AC15T and A. oligospora JCM 10648T was 37.9±0.7 %. On the basis of the phenotypic, phylogenetic and DNA–DNA hybridization data, strain CS5-AC15T is assigned to a novel species of the genus Actinomadura, for which the name Actinomadura rupiterrae sp. nov. is proposed (type strain CS5-AC15T  = KCTC 19559T  = DSM 45251T).

AbstractA novel, non-motile, Gram-stain-positive, non-spore-forming, obligate anaerobic bacterium, designated strain TF01-11T, was isolated from human faeces. The isolate was characterized by phylogenetic and phenotypic properties, as well as by determination of its whole genome sequence. The growth temperature and pH ranges were 30–42 °C and 6.0–8.5, respectively. The end products of glucose fermentation were butyric acid and a small amount of acetic acid. The genome was estimated to be 3.61Mbp with G+C content of 36.79 mol%. Genes related to biosynthesis of diaminopimelic acid, polar lipids, polyamines, teichoic and lipoteichoic acids were present. The predominant fatty acids were C16:0 (37.9 %), C14:0 (16.4 %), C13:0 OH/iso-C15:1 H (11.1 %) and C18:1ω9c (10.6 %). Phylogenetic analyses based on 16S rRNA gene sequences, the isolate was a member of family Lachnospiraceae, with the highest sequence similarity to the type strain of Roseburia intestinalis DSM 14610T at 92.18 % followed by Acetivibrio ethanolgignens ATCC 33324T at 91.99 %. The average nucleotide identity (ANI) calculated for the genomes between strain TF01-11T and these closest relatives were 70.5 % and 68.1 %. Based on results of phenotypic characteristics and genotypic properties presented in this study, strain TF01-11T represent a novel species in a new genus, for which the name Butyribacter intestini gen. nov., sp. nov. is proposed. The type strain of the type species is TF01-11T (CGMCC 1.5203T = CGMCC 10984T = DSM 105140T). In addition, Acetivibrio ethanolgignens is proposed to be reclassified as Acetanaerobacter ethanolgignens gen. nov., comb. nov.

A Gram-positive, non-motile, spherical, non-spore-forming bacterial strain, DS-52T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. It grew optimally at 25 °C and pH 6.0–7.0. Strain DS-52T had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and galactose, mannose, xylose and rhamnose as whole-cell sugars. It contained MK-8(H4) and MK-9(H4) as the predominant menaquinones and anteiso-C15 : 0, iso-C15 : 0 and C17 : 0 as major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyldimethylethanolamine. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-52T is most closely related to the genus Nakamurella of the suborder Frankineae. Strain DS-52T exhibited 16S rRNA gene sequence similarity values of 96.5 % to Nakamurella multipartita JCM 9543T and 92.0–93.9 % to other members of the suborder Frankineae. The diagnostic diamino acid type and polar lipid profile of strain DS-52T were the same as those of the genus Nakamurella. However, strain DS-52T could be clearly distinguished from the genus Nakamurella by differences in predominant menaquinones, major fatty acids and cell-wall sugars. Accordingly, based on combined phenotypic, chemotaxonomic and phylogenetic data, strain DS-52T (=KCTC 19127T=CIP 108919T) is proposed as the type strain of a novel species in a new genus, Humicoccus flavidus gen. nov., sp. nov.

Strain KIT 00200-70066-1T was isolated from the sputum of a patient with pulmonary disease. Cells of the strain were Gram-variable, facultatively anaerobic, motile, spore-forming rods and formed colourless to white colonies on tryptic soy agar at 30 °C and pH 7. The pathogenicity of the strain is not known. The strain contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, MK-7 as the predominant menaquinone, anteiso-C15 : 0, iso-C16 : 0 and C16 : 0 as the major fatty acids and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and several unknown lipids in the polar lipid profile. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus Paenibacillus, sharing the highest levels of sequence similarity with Paenibacillus nanensis MX2-3T, Paenibacillus agaridevorans DSM 1355T and Paenibacillus alkaliterrae KSL-134T (95.4, 95.2 and 94.8 %, respectively), and that it occupied a distinct position within this genus. Combined phylogenetic and phenotypic data supported the conclusion that strain KIT 00200-70066-1T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus sputi sp. nov. is proposed; the type strain is KIT 00200-70066-1T (=KCTC 13252T =DSM 22699T).

Two Gram-staining-positive, aerobic, endospore-forming, motile bacteria, strains DT7-4T and DLE-12T, were isolated from roots of evening primrose (Oenothera biennis) and day lily (Hemerocallis fulva), respectively, and subjected to taxonomic characterization. Analysis of 16S rRNA gene sequences indicated that the two strains fell into two distinct phylogenetic clusters belonging to the genus Paenibacillus. Strain DT7-4T was most closely related to Paenibacillus phyllosphaerae PALXIL04T and Paenibacillus taihuensis THMBG22T, with 96.3 % 16S rRNA gene sequence similarity to each, and strain DLE-12T was most closely related to Paenibacillus ginsengarvi Gsoil 139T and Paenibacillus hodogayensis SGT, with 96.6 and 93.3  % sequence similarity, respectively. Both isolates contained anteiso-C15 : 0 as the dominant fatty acid, meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan and MK-7 as the respiratory menaquinone. The cellular polar lipids were composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and unidentified polar lipids. The DNA G+C contents of strains DT7-4T and DLE-12T were 50.1 ± 0.7 and 55.2 ± 0.5 mol%, respectively. The chemotaxonomic properties of both isolates were typical of members of the genus Paenibacillus. However, our biochemical and phylogenetic analyses distinguished each isolate from related species. Based on our polyphasic taxonomic analysis, strains DT7-4T and DLE-12T should be recognized as representatives of novel species of Paenibacillus, for which the names Paenibacillus oenotherae sp. nov. (type strain DT7-4T = KCTC 33186T = JCM 19573T) and Paenibacillus hemerocallicola sp. nov. (type strain DLE-12T = KCTC 33185T = JCM 19572T) are proposed.
