Bacterium Strain

A novel thermophilic and sulfur-reducing heterotrophic bacterium, strain TFS10-5T, was isolated from a deep-sea hydrothermal field in Yonaguni Knoll IV, Southern Okinawa Trough. Cells of strain TFS10-5T were motile rods, 1.5–5 μm in length and 0.5–0.8 μm in width. Strain TFS10-5T was an obligately anaerobic heterotroph and sulfur-reduction stimulated growth. Growth was observed between 30 and 70 °C (optimum at 55–60 °C), pH 5.0–7.4 (optimum at pH 5.5–5.8), 1.0–5.5 NaCl % (optimum at 3.0–3.5 %). The fatty acid content was C16 : 0 (71.0 %), C16 : 1 (6.0 %), C18 : 0 (21.4 %) and C18 : 1 (1.6 %). The G+C content of the genomic DNA was 28 mol%. 16S rRNA gene sequence analysis indicated that strain TFS10-5T belongs to the genus Marinitoga. Based on the physiological and phylogenetic features of the new isolate, strain TFS10-5T represents a novel species in the genus Marinitoga for which the name Marinitoga okinawensis sp. nov. is proposed. The type strain is TFS10-5T (=JCM 13303T=DSM 17373T).

A novel thermophilic and heterotrophic sulfate-reducing bacterium, strain TFISO9T, was isolated from a deep-sea hydrothermal field at the Yonaguni Knoll IV in the Southern Okinawa Trough. The cells were motile rods 2.5–5.0 μm in length and 0.6–0.9 μm in width. Strain TFISO9T was an obligate heterotroph and reduced sulfate. It grew between 35 and 60 °C (optimum 50 °C), at pH 5.4–7.9 (optimum pH 5.9–6.4) and with 1.5–4.5 % NaCl (optimum 2.5 %). The fatty acid composition was C16 : 0 (61.5 %) and 12Me16 : 0 (38.5 %). The DNA G+C content was 34.9 mol%. The 16S rRNA gene sequence analysis indicated that strain TFISO9T belonged to the genus Desulfothermus. Based on physiological and phylogenetic characteristics, strain TFISO9T represents a novel species for which the name Desulfothermus okinawensis sp. nov. is proposed. The type strain is TFISO9T (=JCM 13304T=DSM 17375T).

Taxonomic Characterization

Nine unidentified Gram-positive, lipophilic corynebacteria were isolated from clinical and food samples and subjected to a polyphasic taxonomic analysis. The bacteria were distinguished from Corynebacterium species with validly published names by biochemical tests, fatty acid content and whole-cell protein analysis. Comparative 16S rRNA gene sequence analysis demonstrated unambiguously that the nine strains were related phylogenetically to the species ‘Corynebacterium tuberculostearicum’ and represented a distinct subline within the genus Corynebacterium. On the basis of both phenotypic and phylogenetic evidence, the formal description of Corynebacterium tuberculostearicum sp. nov. is proposed. The type strain of C. tuberculostearicum is Medalle XT (=LDC-20T=CIP 107291T=CCUG 45418T=ATCC 35529T).

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).

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).

Bacterial isolates obtained from polychlorophenol-contaminated sites in Finland (strain K101T) and from a Dutch drinking water well (strain A175T) were characterized taxonomically. 16S rRNA gene sequence analysis, determination of DNA G+C content, physiological characterization, estimation of the ubiquinone and polar lipid patterns and fatty acid content revealed that strains K101T and A175T were similar to Sphingomonas wittichii RW1T but also showed pronounced differences. The DNA G+C contents of the two novel strains were 63.6 and 66.1 mol%, respectively. On the basis of these results, two novel species of the genus Sphingomonas are described, for which the names Sphingomonas haloaromaticamans sp. nov. [type strain A175T (=DSM 13477T=CCUG 53463T)] and Sphingomonas fennica sp. nov. [type strain K101T (=DSM 13665T=CCUG 53462T)] are proposed.

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).
