A Gram-staining-negative, catalase- and oxidase-positive, non-motile bacterium, designated strain KOPRI 21160T, was isolated from Antarctic soil. Based on 16S rRNA gene sequence analysis, strain KOPRI 21160T was found to belong to the genus Polaribacter . Sequence similarity between strain KOPRI 21160T and the type strains of species of the genus Polaribacter was 94.2–98.3 %. The nearest phylogenetic neighbours of strain KOPRI 21160T were Polaribacter butkevichii KCTC 12100T (98.3 % similarity) and Polaribacter irgensii KCTC 23136T (97.5 %). DNA–DNA relatedness was 50.6 %, between strain KOPRI 21160T and P. butkevichii KCTC 12100T, and 45.2 % between strain KOPRI 21160T and P. irgensii KCTC 23136T. Strain KOPRI 21160T grew at 4–37 °C and at pH 7.0–8.5. It could hydrolyse DNA, starch and Tweens 20, 40, 60 and 80. Menaquinone-6 (MK-6) was the only respiratory quinone, and iso-C15 : 0, iso-C15 : 0 3-OH and C15 : 1ω6c were the major cellular fatty acids. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and one unidentified lipid. The DNA G+C content was 30.0 mol%. Based on data from our polyphasic study, the organism is considered to represent a novel species of the genus Polaribacter , for which we propose the name Polaribacter sejongensis sp. nov. The type strain is KOPRI 21160T ( = KCTC 23670T = JCM 18092T). Emended descriptions of the genus Polaribacter , Polaribacter butkevichii Nedashkovskaya et al. 2005 and Polaribacter irgensii Gosink et al. 1998 are also proposed.

A Gram-staining-negative, aerobic, cream-coloured, marine bacterium, with rod-shaped cells, designated strain YJ-S3-2T, was isolated from salt flat sediment of Yongyu-do, Republic of Korea. YJ-S3-2T grew at pH 5.0–9.0 (optimum pH 7.0), 4–45 °C (optimum 30 °C) and with 1–18 % (w/v) NaCl (optimum 6 %). The results of 16S rRNA gene sequence analysis indicated that YJ-S3-2T was closely related to Marinobacter segnicrescens SS011B1-4T (97.0 %) followed by, ' Marinobacter nanhaiticus ' D15-8W (96.7 %), Marinobacter bryozoorum 50-11T (96.7 %), Marinobacter koreensis DSMZ 179240T T (96.5 %) and Marinobacter bohaiensis T17T (96.5 %). The average nucleotide identity (ANI) and the genome to genome distance calculator (GGDC) estimate values between YJ-S3-2T and related type strains were 73.7–79.8 and 19.9–22.5 %, and also 73.5 and 20.7 % with Marinobacter hydrocarbonoclasticus . YJ-S3-2T was characterized as having Q-9 as the predominant respiratory quinone and the principal fatty acids (>10 %) were C16 : 0 (22.3 %), summed feature 9 (C17 : 1iso ω9c/C16 : 0 10-methyl, 13.8 %) and 3 (C16 : 1ω7c/C16 : 1ω6c, 11.9 %). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids and two unidentified phospholipids. The DNA G+C content of YJ-S3-2T is 60.9 mol%. On the basis of the polyphasic taxonomic evidence presented in this study, YJ-S3-2T should be classified as representing a novel species within the genus Marinobacter , for which name Marinobacter halodurans sp. nov. is proposed, with the type strain YJ-S3-2T (=KACC 19883T=KCTC 62937T=JCM 33109T).

Two Gram-staining-negative, aerobic, rod-shaped bacterial strains, designated Za6a-12T and Za6a-17, were isolated from seawater of the East China Sea. Cells of Za6a-12T and Za6a-17 were approximately 1.5–2.0 µm×0.5–0.7 µm and motile by a single polar flagellum. Strains grew optimally at pH 7.5-8.0, 28 °C, and in the presence of 2.5–3.0 % (w/v) NaCl. Chemotaxonomic analysis showed that the predominant respiratory quinone of strains Za6a-12T and Za6a-17 was ubiquinone-8 (>97 %), and the major fatty acids were C14 : 0, C16 : 1ω7c and/or iso-C15 : 0 2-OH, C16 : 0 and C17 : 1ω8c. Their DNA G+C contents were 42.7 mol% and 42.8 mol%, respectively. 16S rRNA gene sequence analysis revealed that the isolates belonged to the genus Thalassomonas and showed the highest sequence similarity to Thalassomonas loyana CBMAI 722T (95.9 %). Strains Za6a-12T and Za6a-17 could be differentiated from T. loyana CBMAI 722T according to their phenotypic and chemotaxonomic features, DNA G+C contents and fatty acid composition. On the basis of these features, we propose strains Za6a-12T and Za6a-17 to be representatives of a novel species of the genus Thalassomonas with the name Thalassomonas eurytherma sp. nov. suggested. Strain Za6a-12T ( = CGMCC 1.12115T = JCM 18482T) is the type strain of this novel species.

A Gram-staining-negative bacterium, strain TS-T86T, was isolated from Lake Tuosu, a saline lake (salinity 5.4 %, w/w) in Qaidam basin, China. Its taxonomic position was determined by using a polyphasic approach. Strain TS-T86T was strictly heterotrophic, aerobic and catalase- and oxidase-positive. Cells were non-spore-forming, non-motile rods, 0.4–0.6 µm wide and 1.2–2.3 µm long. Growth was observed in the presence of 0–9.0 % (w/v) NaCl (optimum, 2.0 %), at 4–35 °C (optimum, 25 °C) and at pH 7.0–10.5 (optimum, pH 8.5–9.0). Strain TS-T86T contained MK-7 as the predominant respiratory quinone. The major fatty acids (>10 %) were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipids consisted of phosphatidylethanolamine, an unknown phospholipid, six unidentified aminolipids and two uncharacterized lipids. The DNA G+C content was 35 mol% (T m). Phylogenetic trees based on 16S rRNA gene sequences showed that strain TS-T86T was associated with the genus Belliella , and showed the highest sequence similarity to Belliella baltica BA134T (98.5 %) and then to Belliella kenyensis No.164T (95.7 %) and Belliella pelovolcani CC-SAL-25T (95.3 %). DNA–DNA relatedness of strain TS-T86T to Belliella baltica DSM 15883T was 32±3 %. It is concluded that strain TS-T86T represents a novel species of the genus Belliella , for which the name Belliella aquatica sp. nov. is proposed. The type strain is TS-T86T ( = CGMCC 1.12479T = JCM 19468T).

A novel strain, designated strain CU3-7T, was isolated from faeces of a two-week-old baby. The isolate was Gram-staining-positive, anaerobic and rod-shaped. Results from 16S rRNA gene sequence analysis revealed that strain CU3-7T was phylogenetically affiliated with members of the genus Bifidobacterium . Strain CU3-7T showed the highest level of sequence similarity with Bifidobacterium adolescentis KCTC 3216T (98.4 %), followed by Bifidobacterium ruminantium KCTC 3425T (97.9 %). 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).

It grew at 16–37 °C (optimum 25 °C) and at pH 5.0–8.5 (optimum between pH 6.5 and pH 7.0). NaCl was not obligatory for growth but was tolerated at concentrations up to 2.0 % (w/v) NaCl. The novel strain formed yellow colonies on trypticase soy agar. Cells of strain LM2-5T were rods that measured 0.3–0.5 µm in width and 3.0–5.0 µm in length. The predominant respiratory quinone was Q-8. The major fatty acids were iso-C15 : 0 and iso-C17 : 1ω9c. The genomic DNA G+C content was 66.7 mol%. In phylogenetic analyses based on 16S rRNA gene sequences, strain LM2-5T clustered with members of the genus Dokdonella and appeared most closely related to Dokdonella koreensis DS-123T (96.4 % sequence similarity), Dokdonella fugitiva A3T (96.1 %), Dokdonella soli KIS28-6T (95.7 %) and Dokdonella ginsengisoli Gsoil 191T (95.7 %).
