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 novel bacterium, designated strain H3-R18T, was isolated from seashore sand collected from Homi cape, Pohang city, Korea. Cells were Gram-negative, aerobic, non-motile, cream-coloured, mesophilic and slightly halotolerant. 16S rRNA gene sequence analysis indicated that the organism was a member of the genus Pseudomonas, but the sequence showed ⩽96.3 % sequence similarity to that of the type strains of all recognized Pseudomonas species. Highest sequence similarities were to Pseudomonas brenneri CFML 97-391T (96.3 %) and Pseudomonas migulae CIP 105470T (96.3 %). The major fatty acids were summed feature 3 and C16 : 0, with lesser amounts of C12 : 0, C12 : 0 3-OH, C18 : 1ω7c and C14 : 0. The major isoprenoid quinone was Q-9. The DNA G+C content was 64.0 mol%. The phylogenetic, phenotypic and genetic properties of strain H3-R18T suggest that it represents a novel species, for which the name Pseudomonas pohangensis sp. nov. is proposed. The type strain is H3-R18T (=KACC 11517T=DSM 17875T).

An aerobic, Gram-stain-negative, rod-shaped bacterium (strain CC-ALB-1T) was isolated from the rhizosphere of Arabidopsis thaliana. Strain CC-ALB-1T was able to grow at 20–30 °C, pH 5.0–8.0 and with up to 1.0 % (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain CC-ALB-1T had the highest sequence similarity to Chitinophaga ginsengisegetis Gsoil 040T (96.9 %) and Chitinophaga niastensis JS16-4T (96.7 %); lower levels of similarity (<97.0 %) were observed to strains of all other species of the genus Chitinophaga . The fatty acid profile consisted of iso-C15 : 0, iso-C17 : 0 3-OH, C15 : 1ω5c, C16 : 1ω5c and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipid profile contained phosphatidylethanolamine, two unidentified aminolipids and five unidentified lipids. The predominant quinone system was menaquinone 7 (MK-7). The DNA G+C content was 53.4±0.4 mol%. Based on its phylogenetic, phenotypic and chemotaxonomic features, strain CC-ALB-1T is proposed to represent a novel species within the genus Chitinophaga , for which the name Chitinophaga taiwanensis sp. nov. is proposed. The type strain is CC-ALB-1T ( = BCRC 80570T = JCM 18895T).

A Gram-stain-positive, facultatively anaerobic, endospore-forming organism, isolated from the stem of Gossypium hirsutum, was studied to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity comparisons, strain JM-267T was grouped in the genus Bacillus, related most closely to the type strains of Bacillus simplex and Bacillus huizhouensis (both 97.8 %), Bacillus muralis (97.7 %), Bacillus butanolivorans and Bacillus psychrosaccharolyticus (both 97.3 %). 16S rRNA gene sequence similarity to the sequences of the type strains of other Bacillus species was < 97.0 %. The fatty acid profile supported the grouping of the strain to the genus Bacillus. As major fatty acids, anteiso-C15 : 0, iso-C15 : 0, iso-C14 : 0 and iso-C16 : 0 were detected. The polar lipid profile contained the major components diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major quinone was menaquinone 7 (MK-7). DNA–DNA hybridizations with B. simplex DSM 1321T, B. huizhouensis GSS03T, B. muralis LMG 20238T, B. butanolivorans LMG 23974T and B. psychrosaccharolyticus DSM 6T resulted in values clearly below 70 %. In addition, physiological and biochemical test results allowed the clear phenotypic differentiation of strain JM-267T from the most closely related species. Hence, strain JM-267T is considered to represent a novel species of the genus Bacillus, for which the name Bacillus gossypii sp. nov. is proposed. The type strain is JM-267T ( = DSM 100034T = LMG 28742T).

Blastochloris Viridis

A novel Gram-negative, motile, bacteriochlorophyll b-containing purple non-sulfur bacterium, strain JA248T, was isolated from phototrophic enrichments of a yellow–green epilithic biofilm sample collected from Gulmarg, India. The genomic DNA G+C content of strain JA248T was 63.8 mol%. A phylogenetic tree based on 16S rRNA gene sequence analysis showed that strain JA248T had highest similarity to members of the genus Blastochloris and was closely related to Blastochloris sulfoviridis DSM 729T (98.5 % sequence similarity) and Blastochloris viridis DSM 133T (98.4 %) of the class Alphaproteobacteria. Strain JA248T was characterized based on polyphasic taxonomy, and distinct phenotypic and molecular differences based on DNA–DNA hybridization (relatedness of <46.5 % with the two species of the genus Blastochloris), multilocus sequence analysis, and phenotypic and chemotaxonomic evidence separated strain JA248T from other species of the genus Blastochloris. Strain JA248T therefore represents a novel species in the genus Blastochloris, for which the name Blastochloris gulmargensis sp. nov. is proposed. The type strain is JA248T ( = JCM 14795T  = DSM 19786T).

A Gram-negative, aerobic, halophilic, neutrophilic, rod-shaped, non-pigmented, polar-flagellated bacterium, UST010306-043T, was isolated from a pearl-oyster culture pond in Sanya, Hainan Province, China in January 2001. This marine bacterium had an optimum temperature for growth of between 33 and 37 °C. On the basis of 16S rRNA gene sequence analysis, the strain was closely related to Marinomonas aquimarina and Marinomonas communis, with 97.5–97.7 and 97.1 % sequence similarity, respectively. Levels of DNA–DNA relatedness to the type strains of these species were well below 70 %. Analyses of phylogenetic, phenotypic and chemotaxomonic characteristics showed that strain UST010306-043T was distinct from currently established Marinomonas species. A novel species with the name Marinomonas ostreistagni sp. nov. is proposed to accommodate this bacterium, with strain UST010306-043T (=JCM 13672T=NRRL B-41433T) as the type strain.

A cholesterol side-chain-cleaving bacterial strain, AD-6T, was isolated from fresh faeces of a clouded leopard (Neofelis nebulosa) and was studied using a polyphasic taxonomic approach. 16S rRNA gene sequence analysis showed that the novel strain formed a distinct subline within the genus Gordonia, its closest neighbours being the type strains of Gordonia cholesterolivorans, Gordonia sihwensis and Gordonia hydrophobica, with sequence similarity values of 98.2, 97.8 and 97.6 %, respectively. The gyrB gene sequence of strain AD-6T exhibited similarities of 77–91 % with those of the type strains of recognized species of the genus Gordonia, being most similar to the type strains of G. sihwensis, G. hydrophobica and Gordonia hirsuta (91, 87 and 84 % similarity, respectively). The results of whole-cell fatty acid analyses and DNA–DNA relatedness data readily distinguished the new isolate from its nearest neighbours. Strain AD-6T is therefore considered to represent a novel species of the genus Gordonia, for which the name Gordonia neofelifaecis sp. nov. is proposed. The type strain is AD-6T (=NRRL B-59395T=CCTCC AB-209144T).

A Gram-reaction-positive, non-motile, non-spore-forming, aerobic rod, designated BXN5-15T, was isolated from the soil of a ginseng field on Baekdu Mountain in China. Strain BXN5-15T grew optimally at 30 °C and pH 6.0–7.0 in the absence of NaCl on R2A agar. Strain BXN5-15T displayed β-glucosidase activity, which allowed it to transform ginsenoside Rb1 (one of the dominant active components of ginseng) via Rd to minor ginsenoside F2. On the basis of 16S rRNA gene sequence analysis, strain BXN5-15T was shown to belong to the genus Solirubrobacter. The closest phylogenetic relatives were Solirubrobacter soli Gsoil 355T (98.4 % 16S rRNA gene sequence similarity) and Solirubrobacter pauli B33D1T (96.4 %). Lower sequence similarities (<96.0 %) were found with all of the other recognized members of the order Solirubrobacterales. The predominant quinone was MK-7(H4). The major fatty acids (>10 %) were C18 : 1ω9c, iso-C16 : 0 and C18 : 3ω6,9,12c. The G+C content of the genomic DNA was 70.6 mol%. DNA−DNA relatedness between strain BXN5-15T and S. soli KCTC 12628T was 23.3 %. On the basis of genotypic, phenotypic and chemotaxonomic data, strain BXN5-15T represents a novel species within the genus Solirubrobacter, for which the name Solirubrobacter ginsenosidimutans sp. nov. is proposed. The type strain is BXN5-15T ( = KACC 20671T  = LMG 24459T).
