A bacterial strain, PY2T, capable of oxidizing carbon monoxide, was isolated from a soil sample collected from a roadside at Yonsei University, Seoul, Korea. On the basis of 16S rRNA gene sequence analysis, strain PY2T was shown to belong to the genus Terrabacter and was most closely related to Terrabacter lapilli LR-26T (99.1 % similarity). Strain PY2T was characterized chemotaxonomically as having iso-C15 : 0 as the predominant fatty acid, MK-8(H4) as the major menaquinone, ll-diaminopimelic acid as the diagnostic diamino acid of the cell wall, as possessing a polar lipid profile that included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and unknown amino-containing phosphoglycolipids, and having a DNA G+C content of 75.6 mol%. DNA–DNA relatedness values between strain PY2T and the type strains of T. lapilli, Terrabacter tumescens, Terrabacter terrae and Terrabacter aerolatus were 20.0 %, 22.9 %, 35.9 % and 64.5 %, respectively. Based on the combined evidence from the phylogenetic analyses, chemotaxonomic data and DNA–DNA hybridization experiments, it is proposed that strain PY2T represents a novel species for which the name Terrabacter carboxydivorans sp. nov. is proposed. The type strain is PY2T (=KCCM 42922T=JCM 16259T).

The 16S Rrna Gene

A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterium designated SGD-V-25T was isolated from Veraval sediment sample, India. Strain SGD-V-25T was capable of growing at 25–50 °C (optimum 37 °C), pH 6–12 (optimum pH 7.0) and with 0–5 % (w/v) NaCl. The taxonomic position of this strain was deduced using a polyphasic approach and the 16S rRNA gene sequence analysis showed that the isolate belongs to the phylum Firmicutes , forming the cluster with Bacillus badius MTCC 1548T, with which it shares highest similarity of 99.1 % with 13 nt differences. Other type strains of the genus Bacillus showed less than 96 % similarity. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipid profile of strain SGD-V-25T showed the presence of diphosphatidylglycerol, phosphatidylglycerol, phsophoglycolipid and two aminophospholipids. The predominant isoprenoid quinone was MK-7. The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0, C16 : 1ω11c and C16 : 0. The genomic DNA G+C content of strain SGD-V-25T was 37.6 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA hybridization, strain SGD-V-25T could be clearly distinguished from closely related members of the genus Bacillus , and the name Bacillus encimensis sp. nov., is proposed to accommodate this strain. The type strain is SGD-V-25T ( = NCIM 5513T = DSM 28241T).

Chinese Medicinal Plant

Two actinobacterial strains, CPCC 203464T and CPCC 203448, isolated from surface-sterilized stems of medicinal plants were subjected to a polyphasic taxonomic study. These two aerobic organisms formed pale yellow colonies on tryptic soy agar (TSA). Cells were Gram-stain-positive, non-acid-fast, non-motile, rod- or coccoid-like elements. Comparative 16S rRNA gene sequence analysis indicated that strains CPCC 203464T and CPCC 203448 were most closely related to the type strains of the species of the genus Williamsia . Chemotaxonomic properties such as containing meso-diaminopimelic acid in the cell wall, arabinose, galactose and ribose being the whole-cell hydrolysate sugars, phosphatidylethanolamine (PE), diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and phosphatidylinositol (PI) as the phospholipids, and C16 : 0, 10-methyl C18 : 0, C18 : 1ω9c, C16 : 1ω7c and/or iso-C15 : 0 2-OH as major fatty acids supported the affiliation of strains CPCC 203464T and CPCC 203448 to the genus Williamsia . The DNA–DNA hybridization values in combination with differentiating chemotaxonomic and physiological characteristics strongly suggested that these two isolates should be classified as representatives of a novel species of the genus Williamsia . The name Williamsia sterculiae sp. nov. is proposed, with strain CPCC 203464T ( = DSM 45741T = KCTC 29118T) as the type strain.

A Gram-stain-negative, vibrio-shaped, spheroplast-forming, motile, aerobic bacterium was isolated from the soil of a salt desert in Kutch, Gujarat, India. The strain, designated JC232T, was oxidase- and catalase-positive. 16S rRNA gene sequence analysis indicated that strain JC232T was a member of the genus Caenispirillum and was related most closely to Caenispirillum salinarum AK4T (98.9 % similarity) and Caenispirillum bisanense K92T (96.8 %). Genome relatedness based on DNA–DNA hybridization of strain JC232T with the type strains of closely related species was less than 40 %. The DNA G+C content of strain JC232T was 70 mol%. Phosphatidylglycerol, phosphatidylethanolamine, phosphotidylcholine, diphosphatidylglycerol, two unidentified amino lipids (AL1 and 2) and four unidentified lipids (UL1–4) were the polar lipids of strain JC232T. C18 : 1ω7c/C18 : 1ω6c, C16 : 0 and C16 : 1ω7c/C16 : 1ω6c were the major (>15 %) fatty acids of strain JC232T, with minor amounts of C12 : 0, C14 : 0 3-OH/iso-C16 : 0 I, C18 : 1 2-OH, C18 : 0, C16 : 0 3-OH and C19 : 0cycloω8c. Although strain JC232T shared the predominant ubiquinone system (Q10) with the type strains of C. salinarum and C. bisanense, it differed from the latter in polar lipid profile, NaCl growth range and other phenotypic/physiological properties. On the basis of morphological, physiological, genotypic, phylogenetic and chemotaxonomic analyses, strain JC232T is considered to represent a novel species of the genus Caenispirillum, for which the name Caenispirillum deserti sp. nov. is proposed. The type strain is JC232T ( = KCTC 42064T = NBRC 110150T).

A novel Gram-stain-positive, coccoid actinobacterium, designated strain Sco-D01T, was isolated from volcanic ash collected from Oreum (a parasitic volcanic cone) on Jeju Island, Republic of Korea. Cells were aerobic, oxidase-negative and catalase-positive. Colonies were vivid yellow, circular, smooth and convex. The diagnostic diamino acid in the cell wall was ll-diaminopimelic acid. The predominant menaquinone was MK-8(H4). The polar lipids were phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and an unknown phospholipid. The fatty acid profile was represented by large amounts of saturated, unsaturated, 10-methyl and hydroxyl components. The DNA G+C content of strain Sco-D01T was 72.0 mol%. 16S rRNA gene sequence analysis revealed that strain Sco-D01T belonged to the family Nocardioidaceae and formed a distinct sublineage within the radiation of the genus Marmoricola. The level of DNA–DNA relatedness between strain Sco-D01T and its closest phylogenetic relative, Marmoricola aurantiacus DSM 12652T, was 30.2 % (35.4 % in duplicate measurements). On the basis of phenotypic and DNA–DNA hybridization data, strain Sco-D01T is considered to represent a novel species of the genus Marmoricola, for which the name Marmoricola scoriae sp. nov. is proposed.

A novel actinomycete, strain SST-8T, was isolated from sand sediment of Samyang Beach in Jeju, Korea, and subjected to a polyphasic taxonomic study. The organism, which produced opaque, circular, yellow colonies, with a coryneform morphology, showed the following chemotaxonomic characteristics: meso-diaminopimelic acid as the diamino acid in the peptidoglycan, MK-8(H2) as the major menaquinone, phosphatidylglycerol as the only polar lipid, anteiso-C15 : 0 and anteiso-C17 : 0 as major fatty acids and a DNA G+C content of 70.7 mol%. The combination of morphological and chemotaxonomic features supported its classification in the genus Brevibacterium. Phylogenetic analyses, based on 16S rRNA gene sequence studies, showed that strain SST-8T formed an intermediate branch between the Brevibacterium luteolum/Brevibacterium otitidis and Brevibacterium mcbrellneri/Brevibacterium paucivorans clusters. Sequence similarity calculations based on a neighbour-joining analysis revealed that the closest relatives of strain SST-8T were the type strains of B. paucivorans (96.6 %), B. luteolum (96.5 %), B. mcbrellneri (96.3 %), Brevibacterium avium (96.0 %) and B. otitidis (95.9 %). Based on a broad set of phenotypic and genetic data, it was evident that the strain represents a novel species of the genus Brevibacterium. The name Brevibacterium samyangense sp. nov. is proposed, with SST-8T (=NRRL B-41420T=KCCM 42316T) as the type strain.

A bacterial strain designated 11N27T was isolated from an agricultural soil sample. Cells of this strain were Gram-reaction-variable, facultatively anaerobic, endospore-forming, white-pigmented, peritrichously flagellated and hydrolysed xanthine. The major fatty acids of strain 11N27T were anteiso-C15 : 0, iso-C16 : 0 and C16 : 0. The polar lipid profile contained phosphatidylethanolamine, two unknown phospholipids, two unknown aminolipids, one unknown aminophospholipid and two unknown polar lipids. The G+C content of the genomic DNA of strain 11N27T was 50.3 mol%. MK-7 was the predominant respiratory quinone. meso-Diaminopimelic acid was the diagnostic diamino acid in the peptidoglycan. 16S rRNA gene sequence analysis showed that strain 11N27T was phylogenetically related to Paenibacillus mendelii C/2T (96.2  % sequence similarity) and Paenibacillus sepulcri CMM 7311T (96.0  %). The genotypic and phenotypic data showed that strain 11N27T could be distinguished from phylogenetically related species and that this strain represents a novel species of the genus Paenibacillus. The name Paenibacillus xanthinilyticus sp. nov. is proposed with the type strain 11N27T( = KACC 17935T = NBRC 109108T).

A Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1396T) producing a yellow pigment, was isolated from the healthy internal stem tissue of post-harvest cotton (Gossypium hirsutum, cultivar ‘DES-119’) grown at the Plant Breeding Unit at the E. V. Smith Research Center in Tallassee (Macon county), AL, USA. 16S rRNA gene sequence analysis of strain JM-1396T showed high sequence similarity values to the type strains of Novosphingobium mathurense, Novosphingobium panipatense (both 98.6 %) and Novosphingobium barchaimii (98.5 %); sequence similarities to all other type strains of species of the genus Novosphingobium were below 98.3 %. DNA–DNA pairing experiments of the DNA of strain JM-1396T and N. mathurense SM117T, N. panipatense SM16T and N. barchaimii DSM 25411T showed low relatedness values of 8 % (reciprocal 7 %), 24 % (reciprocal 26 %) and 19 % (reciprocal 25 %), respectively. Ubiquinone Q-10 was detected as the dominant quinone; the fatty acids C18 : 1ω7c (71.0 %) and the typical 2-hydroxy fatty acid, C14 : 0 2-OH (11.7 %), were detected as typical components. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. The polyamine pattern contained the major compound spermidine and only minor amounts of other polyamines. All these data revealed that strain JM-1396T represents a novel species of the genus Novosphingobium. For this reason we propose the name Novosphingobium gossypii sp. nov. with the type strain JM-1396T ( = LMG 28605T = CCM 8569T = CIP 110884T).

A Gram-stain-negative bacterium, designated strain Marseille-Q3039T, was isolated from subgingival dental plaque of a woman with gingivitis in Marseille, France. Strain Marseille-Q3039T was found to be an anaerobic, motile and spore-forming crescent-shaped bacterium that grew at 25–41.5 °C (optimum, 37 °C), pH 5.5–8.5 (optimum, pH 7.5) and salinity of 5.0 g l−1 NaCl. The results of 16S rRNA gene sequence analysis revealed that strain Marseille-Q3039T was closely related to Selenomonas infelix ATCC 43532T (98.42 % similarity), Selenomonas dianae ATCC 43527T (97.25 %) and Centipedia periodontii DSM 2778T (97.19 %). The orthologous average nucleotide identity and digital DNA–DNA hybridization relatedness between strain Q3039T and its closest phylogenetic neighbours were respectively 84.57 and 28.2 % for S. infelix ATCC 43532T and 83.93 and 27.2 % for C. periodontii DSM 2778T. The major fatty acids were identified as C13 : 0 (27.7 %), C15 : 0 (24.4 %) and specific C13 : 0 3-OH (12.3 %). Genome sequencing revealed a genome size of 2 351 779 bp and a G+C content of 57.2 mol%. On the basis of the results from phenotypic, chemotaxonomic, genomic and phylogenetic analyses and data, we concluded that strain Marseille-Q3039T represents a novel species of the genus Selenomonas , for which the name Selenomonas timonae sp. nov. is proposed (=CSUR Q3039=CECT 30128).
