A Gram-negative, non-flagellated, motile by gliding, aerobic rod, designated DPG-24T, was isolated from seawater of Geoje Island in the South Sea, Korea. Strain DPG-24T grew optimally at 30–37 °C, at pH 7.0–7.5 and with 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DPG-24T belonged to the genus Winogradskyella and clustered with Winogradskyella poriferorum UST030701-295T and Winogradskyella exilis 022-2-26T. Strain DPG-24T exhibited 97.6 and 95.8 % 16S rRNA gene sequence similarities with W. poriferorum UST030701-295T and W. exilis 022-2-26T, respectively, and 92.4–95.7 % with other members of the genus Winogradskyella . Strain DPG-24T contained MK-6 as the predominant menaquinone and iso-C15 : 1 G, iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine, one unidentified lipid, one unidentified aminolipid and one unidentified phospholipid. The DNA G+C content was 36.7 mol%. DNA–DNA relatedness between the isolate and W. poriferorum JCM 12885T was 10.8 %. The differential phenotypic properties and phylogenetic and genetic distinctiveness enabled strain DPG-24T to be differentiated from recognized members of the genus Winogradskyella . On the basis of the data presented, strain DPG-24T is considered to represent a novel species of the genus Winogradskyella , for which the name Winogradskyella aquimaris sp. nov. is proposed; the type strain is DPG-24T ( = KCTC 23502T  = CCUG 60798T).

A Gram-stain-negative, aerobic, non-flagellated and rod-shaped or ovoid bacterial strain, designated GJSW-36T, was isolated from seawater at Geoje island in the South Sea, South Korea. Strain GJSW-36T grew optimally at pH 7.0–8.0, at 25 °C and in the presence of 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain GJSW-36T fell within the clade comprising the type strains of species of the genus Thalassotalea and Thalassomonas fusca . Strain GJSW-36T exhibited 16S rRNA gene sequence similarity values of 94.2–96.0 % to the type strains of species of the genus Thalassotalea and Thalassomonas fusca and of 93.8–94.5 % to the type strains of the other species of the genus Thalassomonas . Strain GJSW-36T contained ubiquinone-8 (Q-8) as the predominant ubiquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C17 : 1ω8c and C16 : 0 as the major fatty acids. The major polar lipids of strain GJSW-36T were phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content of strain GJSW-36T was 45.1 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain GJSW-36T is separated from species of the genus Thalassotalea and Thalassomonas fusca . On the basis of the data presented, strain GJSW-36T is considered to represent a novel species of the genus Thalassotalea , for which the name Thalassotalea ponticola sp. nov. is proposed. The type strain is GJSW-36T ( = KCTC 42155T = CECT 8656T). From this study, it is also proposed that Thalassomonas fusca should be reclassified as a member of the genus Thalassotalea and the description of the genus Thalassotalea is emended.

A novel Gram-stain-negative, rod-shaped, yellow bacterium, designated as LB1R16T, was isolated from the Laigu glacier on the Tibetan Plateau, PR China. Strain LB1R16T was catalase-positive, oxidase-negative and grew at 0–28 °C, pH 6.0–8.0 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LB1R16T belongs to the family Sphingosinicellaceae but formed an independent lineage. The highest level of 16S rRNA gene sequence similarities were found to Polymorphobacter arshaanensis DJ1R-1T (95.24 %), Sphingoaurantiacus capsulatus YLT33T (94.78 %) and Sandarakinorhabdus limnophila DSM 17366T (94.67 %). The genomic DNA G+C content was 68.8 mol%. The main cellular fatty acids were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c), C16 : 0 and C12 : 0-OH. The respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid, one unidentified phospholipid and two unidentified polar lipids, which were different from the type strains of Polymorphobacter arshaanensis , Sphingoaurantiacus capsulatus and Sandarakinorhabdus limnophila . Based on a polyphasic approach, a novel species of a new genus, Glacieibacterium frigidum gen. nov., sp. nov., within the family Sphingosinicellaceae is proposed. The type strain is LB1R16T (=CGMCC 1.11941T=NBRC 113873T).

Strain SB026T was isolated from Brazilian rainforest soil and its taxonomic position established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological features consistent with its classification in the genus Amycolatopsis and formed a branch in the Amycolatopsis 16S rRNA gene tree together with Amycolatopsis bullii NRRL B-24847T, Amycolatopsis plumensis NRRL B-24324T, Amycolatopsis tolypomycina DSM 44544T and Amycolatopsis vancoresmycina NRRL B-24208T. It was related most closely to A. bullii NRRL B-24847T (99.0 % 16S rRNA gene sequence similarity), but was distinguished from this strain by a low level of DNA–DNA relatedness (~46 %) and discriminatory phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the isolate should be classified in the genus Amycolatopsis as representing a novel species, Amycolatopsis rhabdoformis sp. nov. The type strain is SB026T ( = CBMAI 1694T = CMAA 1285T = NCIMB 14900T).

A novel Gram-negative, aerobic, catalase- and oxidase-positive, non-sporulating, non-motile, rod-shaped bacterium, designated strain UST081027-248T, was isolated from seawater of the Red Sea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain UST081027-248T fell within the genus Erythrobacter . Levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of Erythrobacter species ranged from 95.3 % (with Erythrobacter gangjinensis ) to 98.2 % (with Erythrobacter citreus ). However, levels of DNA–DNA relatedness between strain UST081027-248T and the type strains of closely related species were below 70 %. Optimal growth of the isolate occurred in the presence of 2.0 % NaCl, at pH 8.0–9.0 and at 28–36 °C. The isolate did not produce bacteriochlorophyll a. The predominant cellular fatty acids were C17 : 1ω6c, summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c) and C15 : 0 2-OH. The genomic DNA G+C content of strain UST081027-248T was 60.4 mol%. Phenotypic properties and phylogenetic distinctiveness clearly indicated that strain UST081027-248T represents a novel species of the genus Erythrobacter , for which the name Erythrobacter pelagi sp. nov. is proposed. The type strain is UST081027-248T ( = JCM 17468T = NRRL 59511T).

A polyphasic taxonomic study was performed on two previously unidentified Arcanobacterium -like Gram-positive strains isolated from harbour seals. Comparative 16S rRNA gene sequencing showed that both bacteria belonged to the genus Arcanobacterium and were most closely related to Arcanobacterium haemolyticum CIP 103370T (98.4 % 16S rRNA gene sequence similarity), A. canis P6775T (97.4 %), A. phocae DSM 10002T (97.4 %), A. pluranimalium M430/94/2T (95.7 %) and A. hippocoleae CCUG 44697T (95.5 %). The presence of the major menaquinone MK-9(H4) supported the affiliation of the isolates with the genus Arcanobacterium . The polar lipid profile consisted of major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unidentified phospholipid and two unidentified glycolipids. The major fatty acids were C16 : 0, C18 : 0, C18 : 1ω9c and summed feature 5 (comprising C18 : 2ω6,9c and/or anteiso-C18 : 0). Physiological and biochemical tests clearly distinguished the isolates from other members of the genus Arcanobacterium . Based on the common origin and various physiological properties comparable to those of A. phocae , it is proposed that the isolates are classified as members of a novel species with the name Arcanobacterium phocisimile sp. nov. The type strain is 2698T ( = LMG 27073T  = CCM 8430T).

A Gram-negative, non-motile, non-spore-forming bacterial strain, PR1T, was isolated from a mud core sample containing colonial choanoflagellates near Hog Island, Virginia, USA. Strain PR1T grew optimally at 30 °C and with 3 % (w/v) NaCl. Strain PR1T contained MK-7 as the major menaquinone as well as carotenoids but lacked pigments of the flexirubin-type. The predominant fatty acids were iso-C15 : 0 (29.4 %), iso-C17 : 1ω9c (18.5 %) and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c; 11.3 %). The major polar lipids detected in strain PR1T were phosphatidylethanolamine, an unknown phospholipid, an aminophospholipid, an aminolipid and two lipids of unknown character. The DNA G+C content was 38.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain PR1T fell within the cluster comprising the genus Algoriphagus and was most closely related to Algoriphagus halophilus JC 2051T (95.4 % sequence similarity) and Algoriphagus lutimaris S1-3T (95.3 % sequence similarity). The 16S rRNA gene sequence similarity between strain PR1T and the type strains of other species of the genus Algoriphagus were in the range 91–95 %. Differential phenotypic properties and phylogenetic and genetic distinctiveness of strain PR1T demonstrated that this strain was distinct from other members of the genus Algoriphagus , including its closest relative, A. halophilus . Based on phenotypic, chemotaxonomic, phylogenetic and genomic data, strain PR1T should be placed in the genus Algoriphagus as a representative of a novel species, for which the name Algoriphagus machipongonensis sp. nov. is proposed. The type strain is PR1T ( = ATCC BAA-2233T  = DSM 24695T).
