Gene Sequence Analysis

A Gram-staining-negative, strictly aerobic, non-motile, non-spore-forming, yellow and rod-shaped bacterium, designated E-II-3T, was isolated from ground water at Daejeon in Korea. Strain E-II-3T grew between 4 and 45 °C (optimal growth at 28 °C), between pH 6.0 and 9.0 (optimal growth at pH 7.5) and at salinities of 0–2.0 % (w/v) NaCl, growing optimally with 0.5 % (w/v) NaCl. On the basis of 16S rRNA gene sequence analysis, strain E-II-3T was shown to belong to the genus Novosphingobium and showed closest phylogenetic similarity to ‘Novosphingobium ginsenosidimutans’ FW-6 (97.7 %), Novosphingobium aromaticivorans F199T (96.9 %) and Novosphingobium subterraneum B0478T (96.5 %). The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and sphingoglycolipid. The predominant ubiquinone and polyamine components were Q-10 and spermidine, respectively. The major fatty acids were C18 : 1ω7c (34.0 %), C16 : 1ω7c and/or iso-C15 : 0 2-OH (23.8 %) and C17 : 1ω6c (19.3 %). The DNA G+C content of this novel isolate was 62.7 mol%. DNA–DNA relatedness between strain E-II-3T and ‘N. ginsenosidimutans’ KACC 16615, N. aromaticivorans KCTC 2888T and N. capsulatum KCTC 22844T was 38, 33 and 29 %, respectively. On the basis of polyphasic analysis from this study, strain E-II-3T represents a novel species of the genus Novosphingobium for which the name Novosphingobium aquiterrae sp. nov. is proposed. The type strain is E-II-3T ( = KACC 17599T = NBRC 109812T = NCAIM B 02537T).

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).

Analysis of hsp60 sequences showed that strain CU3-7T was closely related to B. adolescentis KCTC 3216T (94.0 %) and B. ruminantium KCTC 3425T (92.5 %). The DNA–DNA hybridization values with the closely related strains were all below the cut-off value for species delineation, 17.0 % with B. ruminantium KCTC 3425T and 14.9 % with B. adolescentis KCTC 3216T. Fructose-6-phosphate phosphoketolase activity was detected. The predominant cellular fatty acids were C16 : 0 (27.7 %), C18 : 1ω9c (27.4 %) and C18 : 1ω9c dimethylacetate (15.5 %). The DNA G+C content was 58.6 mol%. On the basis of polyphasic taxonomy, strain CU3-7T should be classified as the type strain of a novel species within the genus Bifidobacterium , for which the name Bifidobacterium faecale sp. nov. is proposed ( = KACC 17904T = JCM 19861T).
