A novel Gram-staining-negative, aerobic, non-motile, yellow-to-orange carotenoid-type-pigmented and rod-shaped bacterium, designated strain WP25T, was isolated from the intestine of a comb pen shell, Atrina pectinata, which was collected from the South Sea near Yeosu in Korea. The isolate grew optimally at 20 °C, at pH 7 and with 2 % (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain WP25T belonged to the genus Polaribacter in the family Flavobacteriaceae and the highest sequence similarity was shared with the type strain of Polaribacter sejongensis (98.5 %). The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, C15 : 1ω6c and iso-C15 : 0 3-OH. The main respiratory quinone was menaquinone MK-6. The polar lipids of strain WP25T were phosphatidylethanolamine, two unidentified aminolipids, an unidentified phospholipid and four unidentified lipids. The genomic DNA G+C content was 31.2 mol%. DNA–DNA hybridization experiments indicated <12.6 % genomic relatedness with closely related strains. Based on phylogenetic, phenotypic and genotypic analyses, strain WP25T represents a novel species in the genus Polaribacter , for which the name Polaribacter atrinae sp. nov. is proposed, with the type strain WP25T ( = KACC 17473T = JCM 19202T).

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).

Two novel strains (HMF3257T and HMF4905T), isolated from freshwater and bark samples, were investigated to determine their relationships within and between species of the genus Spirosoma by using a polyphasic approach. They were aerobic, Gram-stain-negative, non-motile and rod-shaped bacteria. The major fatty acids (>10%) in both strains were identified as summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and C16 : 1 ω5c, while strains HMF3257T and HMF4905T contained a moderately high amount of C16 : 0 and iso-C15 : 0, respectively. The predominant respiratory quinone was MK-7 for both strains. In addition to phosphatidylethanolamine and one unidentified glycolipid, the polar lipid profile of strain HMF3257T consisted of three unidentified aminophospholipids, one unidentified aminolipid and two unidentified polar lipids, and that of strain HMF4905T consisted of one unidentified aminophospholipid, two unidentified aminolipids and three unidentified polar lipids. The DNA G+C contents of strains HMF3257T and HMF4905T were 47.2 and 46.4 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains HMF3257T and HMF4905T are closely related to Spirosoma migulaei 15J9-8T (97.0 % sequence similarity), while sharing 97.4 % sequence similarity with each other. The average nucleotide identity value between strains HMF3257T and HMF4905T was 81.1 %, and the digital DNA–DNA hybridization value between these two strains was 24.4 %. Based on the above data, strains HMF3257T and HMF4905T represent two novel members within the genus Spirosoma , for which the names Spirosoma telluris sp. nov. and Spirosoma arboris sp. nov. are proposed, respectively. The type strain of S. telluris is HMF3257T (=KCTC 62463T=NBRC 112670T) and type strain of S. arboris is HMF4905T (=KCTC 72779T=NBRC 114270T).

A Gram-staining-negative, rod-shaped, gliding and pale-pink-pigmented bacterium, designated strain ZLM-10T, was isolated from a soil sample collected from an arid area in Xinjiang province, China, and characterized in a taxonomic study using a polyphasic approach. The novel strain grew optimally at 30–37 °C and in the presence of 2 % (w/v) sea salts. The only respiratory quinone detected was MK-7 and the major cellular fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and two unidentified aminophospholipids. The DNA G+C content was 45.4 mol%. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZLM-10T was a member of the phylum Bacteroidetes and appeared most closely related to Cesiribacter roseus 311T (90.2 % sequence similarity), Marivirga sericea LMG 13021T (89.2 %), Cesiribacter andamanensis AMV16T (89.1 %) and Marivirga tractuosa DSM 4126T (89.1 %). On the basis of phenotypic and genotypic data and phylogenetic inference, strain ZLM-10T should be classified as a novel species of a new genus in the family Flammeovirgaceae , for which the name Nafulsella turpanensis gen. nov., sp. nov. is proposed. The type strain of the type species is ZLM-10T ( = CCTCC AB 208222T = KCTC 23983T).

A Gram-stain-negative, non-motile, mesophilic, aerobic, rod-shaped bacterium, designated strain 2-3T, was isolated from surface seawater at Muroto city, Kochi prefecture, Japan. This strain grew well with starch. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain fell within the family Rhodobacteraceae and that the strain was related most closely to the genus Pacificibacter (94.0 % sequence similarity to the type strain). The DNA G+C content was 52.4 mol%. The major fatty acids were C18 : 1ω7c, C14 : 0 and C16 : 0. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, one unidentified lipid, one unidentified aminolipid and one unidentified phospholipid. The major isoprenoid quinone was Q-10. Strain 2-3T did not grow at 4 or 35 °C, while the type strain of the type species of the genus Pacificibacter grows at both temperatures.

Four Gram-staining-positive, catalase-negative, coccoid isolates, designated NTUH_1465T, NTUH_2196, NTUH_4957 and NTUH_5572T, were isolated from human specimens. The four isolates displayed more than 99.6 % 16S rRNA gene sequence similarity with Gemella haemolysans ATCC 10379T, and 96.7 to 98.6 % similarity with Gemella sanguinis ATCC 700632T, Gemella morbillorum ATCC 27824T or Gemella cuniculi CCUG 42726T. However, phylogenetic analysis of concatenated sequences of three housekeeping genes, groEL, rpoB and recA, suggested that the four isolates were distinct from G. haemolysans ATCC 10379T and other species. Isolates NTUH_2196, NTUH_4957 and NTUH_5572T clustered together and formed a stable monophyletic clade. DNA–DNA hybridization values among strains NTUH_1465T and NTUH_5572T and their phylogenetically related neighbours were all lower than 49 %. The four isolates could be distinguished from G. haemolysans and other species by phenotypic characteristics. Based on the phylogenetic and phenotypic results, two novel species Gemella parahaemolysans sp. nov. (type strain NTUH_1465T = BCRC 80365T = JCM 18067T) and Gemella taiwanensis sp. nov. (type strain NTUH_5572T = BCRC 80366T = JCM 18066T) are proposed.
