An orange-coloured bacterial strain, designated R2A15-11T, was isolated from greenhouse soil. The strain was found to be strictly aerobic, Gram-negative, non-spore-forming and non-flagellated. The cells were short rods (0.7–0.9×1.0–1.5 μm) and produced flexirubin. Growth of the strain was observed at 10–35 °C, pH 5.0–8.0 and 0–3 % (w/v) NaCl. The predominant isoprenoid quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1 ω7c). The genomic DNA G+C content was 45.0 mol%. Phylogenetic analysis of the 16S rRNA gene sequence of strain R2A15-11T revealed a clear affiliation with the phylum Bacteroidetes, and the highest levels of sequence similarity were found with respect to Terrimonas ferruginea ATCC 13524T (91.5 %), Terrimonas lutea DYT (90.2 %), Niastella yeongjuensis GR20-13T (89.9 %) and Niastella koreensis GR20-10T (89.7 %). On the basis of the polyphasic evidence from this study, strain R2A15-11T represents a novel genus and species, for which the name Niabella aurantiaca gen. nov., sp. nov. is proposed. The type strain of Niabella aurantiaca is R2A15-11T (=KACC 11698T=DSM 17617T).

AbstractStrain SN6T is a non-motile and non-spore-forming gram-negative bacterium which was isolated from the stool sample of an Amazonian patient. The optimum growth was observed at 37 °C, pH 7, and 0–5 g/l of NaCl. Based on the 16S rRNA gene sequence similarity, the strain SN6T exhibited 97.5% identity with Vitreoscilla stercoraria strain ATCC_15218 (L06174), the phylogenetically closest species with standing in nomenclature. The predominant fatty acid was hexadecenoic acid (31%). The genomic DNA G + C content of the strain SN6T was 49.4 mol %. After analysis of taxonogenomic data, phenotypic and biochemical characteristics, we concluded that strain SN6T represents a new species of the genus Vitreoscilla for which the name Vitreoscilla massiliensis sp.nov is proposed. The type strain is SN6T (=CSUR P2036 = LN870312 = DSM 100958).

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).

A Gram-reaction-positive, rod-shaped, spore-forming bacterium, designated Gsoil 1105T, was isolated from soil of a ginseng field in Pocheon Province in South Korea and characterized in order to determine its taxonomic position. Comparative analysis of the 16S rRNA gene sequence showed that the isolate belongs to the order Bacillales, showing the highest level of sequence similarity with respect to Tumebacillus permanentifrigoris Eur1 9.5T (94.6 %). The phylogenetic distances from other described species with validly published names within the order Bacillales were greater than 9.0 %. Strain Gsoil 1105T had a genomic DNA G+C content of 55.6 mol% and menaquinone 7 (MK-7) as the major respiratory quinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1105T represents a novel species of the genus Tumebacillus, for which the name Tumebacillus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 1105T ( = KCTC 13942T  = DSM 18389T).

A Gram-positive, aerobic, non-motile and coccoid actinobacterium, designated P31T, was isolated from a traditional, fermented seafood. The strain was catalase-positive and oxidase-negative. Cells grew in the presence of 0–15.0 % (w/v) NaCl, and at pH 5–10 and 15–37 °C. Major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. Strain P31T contained MK-7 as the predominant menaquinone. The DNA G+C content of the genomic DNA of strain P31T was 65.2 mol%. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain P31T was most closely related to Kocuria kristinae DSM 20032T, with 96.9 % similarity, and these two strains clustered together in constructed phylogenetic trees. The DNA–DNA hybridization value between strain P31T and K. kristinae DSM 20032T was 21.1 %. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, it is suggested that strain P31T represents a novel species of the genus Kocuria, for which the name Kocuria koreensis sp. nov. is proposed. The type strain is P31T (=KCTC 19595T=JCM 15915T).

A Gram-negative, strictly aerobic bacterium, designated CL-ES53T, was isolated from surface water of the East Sea in Korea. Cells of strain CL-ES53T were short rods and motile by means of monopolar flagella. Strain CL-ES53T grew with 4–21 % NaCl (optimum 10 %) and at 5–40 °C (optimum 25 °C) and pH 5.2–8.8 (optimum pH 6.3–7.2). The major isoprenoid quinone was Q-8. The major fatty acids were C18 : 1 ω7c (42.0 %), C18 : 1 ω9c (14.8 %) and C14 : 0 (9.4 %). The genomic DNA G+C content was 64.9 mol%. Analysis of the 16S rRNA gene sequence of strain CL-ES53T revealed that it was a member of the genus Salinisphaera and most closely related to Salinisphaera shabanensis E1L3A T (96.9 % sequence similarity) and Salinisphaera hydrothermalis EPR70T (93.8 %). Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain CL-ES53T formed a robust cluster with S. shabanensis E1L3A T. Although the 16S rRNA gene sequence similarity between strain CL-ES53T and S. shabanensis E1L3A T was rather high (96.9 %), DNA–DNA relatedness between these strains was 12 %, suggesting that they represent genomically distinct species. Strain CL-ES53T was differentiated from S. shabanensis E1L3A T and S. hydrothermalis EPR70T on the basis of optimum temperature for growth and certain phenotypic characteristics. The phylogenetic analysis and physiological and chemotaxonomic data show that strain CL-ES53T should be classified in the genus Salinisphaera within a novel species, for which the name Salinisphaera dokdonensis sp. nov. is proposed. The type strain is CL-ES53T (=KCCM 90064T =DSM 19549T).

Five strains of strictly aerobic, heterotrophic bacteria that form pink–red colonies and are capable of hydrolysing pectin, xylan, laminarin, lichenan and starch were isolated from acidic Sphagnum peat bogs and were designated OB1010T, LCBR1, TPB6011T, TPB6028T and TPO1014T. Cells of these isolates were Gram-negative, non-motile rods that produced an amorphous extracellular polysaccharide-like substance. Old cultures contained spherical bodies of varying sizes, which represent starvation forms. Cells of all five strains were acidophilic and psychrotolerant, capable of growth at pH 3.0–7.5 (optimum pH 3.8–4.5) and at 2–33 °C (optimum 15–22 °C). The major fatty acids were iso-C15 : 0, C16 : 0 and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH). The major menaquinone detected was MK-8. The pigments were carotenoids. The genomic DNA G+C contents were 57.3–59.3 mol%. The five isolates were found to be members of subdivision 1 of the phylum Acidobacteria and displayed 95.3–98.9 % 16S rRNA gene sequence similarity to each other. The closest described relatives to strains OB1010T, LCBR1, TPB6011T, TPB6028T, and TPO1014T were members of the genera Terriglobus (94.6–95.8 % 16S rRNA gene sequence similarity) and Edaphobacter (94.2–95.4 %). Based on differences in cell morphology, phenotypic characteristics and hydrolytic capabilities, we propose a novel genus, Granulicella gen. nov., containing four novel species, Granulicella paludicola sp. nov. with type strain OB1010T (=DSM 22464T =LMG 25275T) and strain LCBR1, Granulicella pectinivorans sp. nov. with type strain TPB6011T (=VKM B-2509T =DSM 21001T), Granulicella rosea sp. nov. with type strain TPO1014T (=DSM 18704T =ATCC BAA-1396T) and Granulicella aggregans sp. nov. with type strain TPB6028T (=LMG 25274T =VKM B-2571T).

Two strains belonging to the genus Shewanella, HAW-EB2T and HAW-EB5T, were isolated previously from marine sediment sampled from the Atlantic Ocean, near Halifax harbour in Canada, for their potential to degrade explosive hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). In the present study, strains HAW-EB2T and HAW-EB5T were found to display high 16S rRNA gene sequence similarity (90–99.5 %) to species of Shewanella, but their gyrB sequences were significantly different from each other and from species of Shewanella (79–87.6 %). Furthermore, DNA–DNA hybridization showed that the genomic DNA of the two strains was only 22 % related and showed less than 41 % relatedness to closely related species of Shewanella. In comparison to other species of Shewanella, strains HAW-EB2T and HAW-EB5T were also unique in some phenotypic properties such as activities of β-galactosidase and tyrosine arylamidase and the ability to metabolize certain organic acids and sugars. Both strains HAW-EB2T and HAW-EB5T utilize malate, valerate, peptone and yeast extract as sole carbon and energy sources. The major membrane fatty acids of the two strains were C14 : 0, iso-C15 : 0, C16 : 0, C16 : 1 ω7, C18 : 1 ω7 and C20 : 5 ω3 and their major quinones were Q-7, Q-8 and MK-7. On the basis of these results, strain HAW-EB2T (=NCIMB 14238T =CCUG 54553T) is proposed as the type strain of Shewanella canadensis sp. nov. and strain HAW-EB5T (=NCIMB 14239T =CCUG 54554T) is proposed as the type strain of Shewanella atlantica sp. nov.

The taxonomic properties of strain DC2a-G7T, a Gram-negative, ovoid to rod-shaped, gellan gum-lysing bacterium, were examined. The 16S rRNA gene sequence similarity showed that DC2a-G7T is a member of the phylum Verrucomicrobia and the closest type strain of a species with a validly published name is Verrucomicrobium spinosum DSM 4136T, with a sequence similarity of 91.2 %. In addition to this similarity value lower than 95 %, the absence of prostheca, the orangey-red colony colour and the compositions of the major menaquinones and polar lipids also supported the differentiation of this bacterium from the genus Verrucomicrobium . Here, we propose the name Roseimicrobium gellanilyticum gen. nov., sp. nov. for the isolate. The type strain of Roseimicrobium gellanilyticum is DC2a-G7T ( = NBRC 108606T = DSM 25532T).

A novel solvent-producing, anaerobic clostridium, strain P7T, was isolated from sediment from an agricultural settling lagoon after enrichment with CO as the substrate. The metabolism of this Gram-positive, motile, spore-forming rod was primarily acetogenic. Acetate, ethanol, butyrate and butanol were the end-products of metabolism. Strain P7T grew on CO, H2/CO2, glucose, galactose, fructose, xylose, mannose, cellobiose, trehalose, cellulose, starch, pectin, citrate, glycerol, ethanol, propanol, 2-propanol, butanol, glutamate, aspartate, alanine, histidine, asparagine, serine, betaine, choline and syringate as sole substrates. Growth was not supported by methanol, formate, d-arabinose, fucose, lactose, melibiose, amygdalin, gluconate, lactate, malate, arginine, glutamine or vanillate. Nitrate reduction, production of indole, gelatin hydrolysis and aesculin hydrolysis were not observed. Analysis of the 16S rRNA gene sequence of the isolate showed that it was closely related to Clostridium scatologenes ATCC 25775T (99·7 % sequence similarity) and clostridial strain SL1T (99·8 % sequence similarity). Strain SL1 had been classified as a strain of C. scatologenes. However, DNA–DNA reassociation analysis showed that both strain P7T and strain SL1 represented novel clostridial species. It is proposed that strain P7T (=ATCC BAA-624T=DSM 15243T) be classified as the type strain of Clostridium carboxidivorans sp. nov. and that strain SL1T (=ATCC BAA-623T=DSM 12750T) be reclassified as the type strain of Clostridium drakei sp. nov.
