Gene Sequence Analysis

A halo- and organo-sensitive oligotrophic bacterium, designated strain SY-6T, was isolated from humus forest soil at Gyeryong mountain in Korea. Cells of the strain were Gram-negative, strictly aerobic, non-motile rods and the strain formed yellow-pigmented colonies on 100-fold-diluted nutrient broth. Strain SY-6T grew at pH 6.0–7.0 (optimal growth at pH 7.0), at 10–37 °C (optimal growth at 28 °C) and at salinities of 0–0.5 % (w/v) NaCl, growing optimally at 0.01 % (w/v) NaCl. On the basis of 16S rRNA gene sequence analysis, strain SY-6T was shown to belong to the genus Sphingomonas and showed the closest phylogenetic similarity to Sphingomonas polyaromaticivorans B2-7T (96.7 %). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. The predominant ubiquinone and polyamine were Q-10 and sym-homospermidine, respectively. The major fatty acids were C18 : 1ω7c and C16 : 0. The DNA G+C content of the novel isolate was 65.3 mol%. On the basis of the evidence from this polyphasic study, strain SY-6T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas oligoaromativorans sp. nov. is proposed. The type strain is SY-6T ( = KACC 12948T = NBRC 105508T).

A Gram-stain-negative, rod-shaped, orange-coloured, catalase- and oxidase-positive, non-motile bacterium, designated strain 92VT, was isolated from the marine sponge Amphilectus fucorum, collected from Lough Hyne, County Cork, Ireland. 16S rRNA gene sequence analysis revealed that strain 92VT clustered with members of the family Flavobacteriaceae , the closest member being Aquimarina latercula NCIMB 1399T, with a gene sequence similarity of 97.5 %. Strain 92VT required seawater for growth with optimal growth occurring at 25 °C, at pH 6–7 and with 3 % (w/v) NaCl. MK-6 was the sole respiratory quinone present and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0, iso-C17 : 1ω9c and iso-C15 : 0 3-OH. The DNA G+C content was 36.1 mol%. Combined phenotypic differences and phylogenetic analysis indicate that strain 92VT represents a novel species of the genus Aquimarina , for which the name Aquimarina amphilecti sp. nov. is proposed. The type strain is 92VT ( = NCIMB 14723T = DSM 25232T).

A Gram-stain-positive, strictly aerobic, non-motile, coccoid bacterium, designated NCCP-154T, was isolated from citrus leaf canker lesions and was subjected to a polyphasic taxonomic study. Strain NCCP-154T grew at 10–37 °C (optimum 30 °C) and at pH 7.0–8.0 (optimum pH 7.0). The novel strain exhibited tolerance of UV irradiation (>1000 J m−2). Based on 16S rRNA gene sequence analysis, strain NCCP-154T showed the highest similarity to Deinococcus gobiensis CGMCC 1.7299T (98.8 %), and less than 94 % similarity to other closely related taxa. The chemotaxonomic data [major menaquinone, MK-8; cell-wall peptidoglycan type, A3β (Orn–Gly2); major fatty acids, summed feature 3 (C16 : 1ω7c/iso-C15 : 0 2-OH; 35.3 %) followed by C16 : 0 (12.7 %), iso-C17 : 1ω9c (9.2 %), C17 : 1ω8c (7.4 %) and iso-C17 : 0 (6.9 %); major polar lipids made up of several unidentified phosphoglycolipids and glycolipids and an aminophospholipid, and mannose as the predominant whole-cell sugar] also supported the affiliation of strain NCCP-154T to the genus Deinococcus . The level of DNA–DNA relatedness between strain NCCP-154T and D. gobiensis JCM 16679T was 63.3±3.7 %. The DNA G+C content of strain NCCP-154T was 70.0 mol%. Based on the phylogenetic analyses, DNA–DNA hybridization and physiological and biochemical characteristics, strain NCCP-154T can be differentiated from species with validly published names. Therefore, it represents a novel species of the genus Deinococcus . The name Deinococcus citri sp. nov. is proposed, with the type strain NCCP-154T ( = JCM 19024T = DSM 24791T = KCTC 13793T).

Genotypic Characteristics

A novel Gram-stain–positive, filamentous bacterial strain (A-T 7458T) was isolated from soil collected from hill evergreen forest in Thailand. The strain developed cylindrical sporangia containing a longitudinal pair of motile spores, on short ramifications of aerial mycelia. From a taxonomic study using a polyphasic approach, strain A-T 7458T had typical characteristics of members of the genus Planobispora . 16S rRNA gene sequence analysis indicated that the isolate was closely related to Planobispora siamensis A-T 4600T (98.5 %), Planobispora rosea JCM 3166T (97.6 %) and Planobispora longispora NBRC 13918T (97.6 %). The DNA–DNA relatedness values, which differentiated the novel strain from the closest species, were significantly below 70 %. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, madurose, mannose and glucose. The predominant menaquinone was MK-9(H2). The diagnostic phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylinositol-mannoside and aminophosphoglycolipid. The predominant cellular fatty acids were unsaturated C17 : 1 and C18 : 1, and saturated C16 : 0 and C17 : 0. Following an evaluation of phenotypic, chemotaxonomic and genotypic characteristics, the novel isolate is proposed to represent a novel species of the genus Planobispora , to be named Planobispora takensis sp. nov. The type strain is A-T 7458T ( = BCC 48396T = NBRC 109077T).

A Gram-stain-negative, strictly aerobic, non-motile, long, straight-rod and non-flagellated marine bacterium strain, designated SCR12T, was isolated from the gill of a shrimp collected in the Tangyin hydrothermal field of the Okinawa Trough. The growth temperature was in the range of 16–40 °C and the optimum temperature was 37 °C. Optimal growth occurred at pH 6.5 and in the presence of 3 % (w/v) NaCl. The predominant isoprenoid quinone of strain SCR12T was menaquinone-6 (MK-6). The predominant fatty acids (>10 %) were iso-C15 : 0 (44.2 %), iso-C15 : 1 G (19.0 %) and iso-C17 : 0 3-OH (12.1 %). The major polar lipids comprised one phosphatidylethanolamine, three unidentified phospholipids, two unidentified aminolipids and three unidentified lipids. Based on the results of 16S rRNA gene sequence analysis, strain SCR12T was found to be most closely related to Muricauda olearia CL-SS4T (98.09 %), followed by Muricauda beolgyonensis BB-My12T (97.65 %), Muricauda aquimarina SW-63T (97.58 %) and Muricauda ruestringensis DSM 13258T (97.31 %) and with lower sequence similarities (95.74–97.10 %) to other species of the genus Muricauda . Genome relatedness between strain SCR12T and M. olearia CL-SS4T was computed using both average nucleotide identity (ANI) and DNA–DNA hybridization (DDH) and resulted in values of 85.6 % and 29.3±2.3 %, respectively. The genomic DNA G+C content of strain SCR12T was 42.3 mol%. On the basis of polyphasic analysis, the strain SCR12T was considered to represent a novel species of the genus Muricauda, for which the name Muricauda alvinocaridis sp. nov. is proposed. The type strain is SCR12T (=MCCC 1K03731T=JCM 33425T).
