A novel aromatic-compound-degrading bacterium, strain T3-B9T, was isolated from sediment of Taihu Lake, Jiangsu Province, south-east China. This bacterial isolate assimilated several aromatic compounds such as phenol, aniline, nitrobenzene, 4-chloronitrobenzene and phenanthrene. The taxonomy of strain T3-B9T was studied by polyphasic methods. The organism showed a range of phenotypic and chemotaxonomic properties consistent with those of the genus Novosphingobium. The 16S rRNA gene sequence similarity of strain T3-B9T to members of the genus Novosphingobium ranged from 91·6 to 97·5 %, and this isolate clustered phylogenetically with members of genus Novosphingobium. The DNA–DNA relatedness values of strain T3-B9T to the most phylogenetically related species, Novosphingobium subterraneum DSM 12447T, Novosphingobium aromaticivorans ATCC 700278T and Novosphingobium stygium ATCC 700280T, were 31, 33 and 14 %, respectively. The combined genotypic and phenotypic data show that strain T3-B9T represents a novel species of the genus Novosphingobium, for which the name Novosphingobium taihuense sp. nov. is proposed. The type strain is T3-B9T (=AS 1.3432T=JCM 12465T).

The 16S Rrna Gene

A Gram-positive-staining, non-motile, rod- or coccoid-shaped bacterium, strain CLGT, was isolated from beach sand from Lianyungang, Jiangsu Province, PR China. The organism grew optimally at 30 °C and pH 7.0. Strain CLGT contained l-Lys–d-Asp as the peptidoglycan type and galactose, rhamnose and xylose as the whole-cell sugars. It contained anteiso-C15 : 0 and iso-C15 : 0 as the major fatty acids. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phospholipid, phosphatidylinositol, three phosphoglycolipids and one unidentified lipid. The DNA G+C content was 70.3 mol%. The 16S rRNA gene sequence similarity of strain CLGT with Isoptericola dokdonensis DS-3T was 99.4 % but the DNA–DNA relatedness between strain CLGT and I. dokdonensis DS-3T was 58.7 %. There were also many phenotypic properties that distinguished strain CLGT from recognized species of the genus Isoptericola. The results showed that strain CLGT represents a novel species of the genus Isoptericola, for which the name Isoptericola jiangsuensis sp. nov. is proposed. The type strain is CLGT (=DSM 21863T=CCTCC AB208287T).

A Gram-positive, yellowish bacterium strain AK-1Twas isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genusAgromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1Twas closely related toAgromyces aurantiacus(98.6%) followed byAgromyces soli(98.3%),Agromyces tropicus(97.6%),Agromyces ulmi(97.3%),Agromyces flavus(97.2%), andAgromyces italicus(97.0%), whereas the sequence similarity values with respect to the otherAgromycesspecies with validly published names were between 95.3 and 96.7 %. However, the DNA-DNA hybridization values obtained between strain AK-1Tand other related strains were well below the threshold that is required for the proposal of a novel species. The DNAG+Ccontent of the strain is 71.8 mol%. The above data in combination with the phenotypic distinctiveness of AK-1Tclearly indicate that the strain represents a novel species, for which the nameAgromyces arachidissp. nov. is proposed. The type strain is AK-1T(=MTCC 10524T= JCM 19251T).

A Gram-reaction-positive, rod-shaped, non-motile, non-spore-forming bacterium (strain BX5-10T) was isolated from the soil of a ginseng field on Baekdu Mountain in Jilin district, China. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain BX5-10T was shown to belong to the family Nocardioidaceae and to be most closely related to Nocardioides plantarum NCIMB 12834T (96.5 % sequence similarity), Nocardioides dokdonensis KCTC 19309T (96.2 %) and Nocardioides fonticola NAA-13T (95.1 %). Strain BX5-10T was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone and C18 : 1ω9c, C16 : 0 and C17 : 1ω8c as its major fatty acids. The G+C content of the genomic DNA was 70.3 mol%. The novel strain could be differentiated genotypically and phenotypically from all recognized species of the genus Nocardioides. Based on the results of the phylogenetic analyses and the genotypic and phenotypic data, a novel species, Nocardioides ginsengagri sp. nov., is proposed. The type strain is BX5-10T ( = KCTC 19467T = DSM 21362T).

Two Gram-stain-negative, rod-shaped, orange, catalase- and oxidase-positive, non-motile bacteria, designated W13M1AT and W15M10T, were isolated from the marine sponges Suberites carnosus and Leucosolenia sp., respectively, which were sampled from Lough Hyne, Co. Cork, Ireland. Analysis of the 16S rRNA gene sequences of these isolates revealed that they are members of the genus Maribacter, in the family Flavobacteriaceae of the phylum Bacteroidetes. The type strain most closely related to strain W13M1AT is Maribacter forsetii DSM 18668T with a gene sequence similarity of 96.5 %. The closest related type strain to strain W15M10T is Maribacter orientalis DSM 16471T with a gene sequence similarity of 98.3 %. Phylogenetic inference and phenotypic data combined indicate that the isolates represent two novel species of the genus Maribacter, for which the names Maribacter spongiicola sp. nov. with type strain W15M10T ( = NCIMB 14725T = DSM 25233T) and Maribacter vaceletii sp. nov. with type strain W13M1AT ( = NCIMB 14724T = DSM 25230T), are proposed.

A Gram-stain-positive, endospore-forming, rod-shaped bacterium, designated XJ259T, was isolated from a cold spring sample from Xinjiang Uyghur Autonomous Region, China. The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).

Sequence Similarities

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 pink-coloured bacterial strain, 5516J-15T, was isolated from an air sample from Jeju Island, Republic of Korea. The organism was found to have resistance to UV radiation typical of members of the genus Deinococcus, and it was placed within the radiation of the Deinococcus on a phylogenetic tree based on 16S rRNA gene sequences. Strain 5516J-15T shared low 16S rRNA gene sequence similarity (84.5–87.8 %) with Deinococcus species, showing highest sequence similarity to Deinococcus deserti VCD115T (87.8 %) and Deinococcus indicus Wt/1aT (87.8 %). Strain 5516J-15T had type A3β peptidoglycan with l-ornithine, menaquinone 8 (MK-8) as the major quinone and iso-C12 : 0, anteiso-C13 : 0, iso-C16 : 0 and C16 : 0 as the major fatty acids. Its polar lipid profile contained three unknown aminophospholipids, two unknown polar lipids, one unknown phospholipid and one unknown glycolipid. The DNA G+C content of strain 5516J-15T was 61.3 mol%. Based on the phylogenetic and phenotypic data presented, it is proposed that the unknown strain should be classified within a novel species in the genus Deinococcus with the name Deinococcus cellulosilyticus sp. nov. The type strain is 5516J-15T (=KACC 11606T =DSM 18568T).

An actinomycete, designated strain GIMN4.003T, was isolated from seawater collected in Sanya, China. It produced white aerial mycelium and yellow substrate mycelium on Gause’s synthetic agar medium no. 1. The substrate mycelium colour was not sensitive to pH. Scanning electron microscopy observations revealed that GIMN4.003T produced straight to flexuous spore chains of rough to warty spores. ll-Diaminopimelic acid was present in the cell-wall hydrolysate. Based on chemotaxonomy and morphological features, strain GIMN4.003T was identified as a member of the genus Streptomyces. Melanin was not produced. No antimicrobial activity was detected against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Penicillium citrinum or Candida albicans. Analysis of the 16S rRNA gene sequence revealed that the highest sequence similarity was to Streptomyces radiopugnans R97T (99.0 %). However, DNA relatedness between GIMN4.003T and S. radiopugnans DSM 41901T was low (41.24±1.47 %). Furthermore, the morphological, physiological and biochemical characteristics of strain GIMN4.003T were different from those of S. radiopugnans DSM 41901T and the type strains of other closely related Streptomyces species. On the basis of its physiological and molecular properties, it is evident that strain GIMN4.003T ( = CCTCCM 208215T  = NRRL B-24801T) represents the type strain of a novel species within the genus Streptomyces, for which the name Streptomyces fenghuangensis sp. nov. is proposed.
