A Gram-negative, non-motile, ovoid to rod-shaped bacterium, designated HDW-32T, was isolated from seawater of the Yellow Sea, Korea. Strain HDW-32T grew optimally at pH 7–8, at 30 °C and with 2–3 % (w/v) NaCl. Strain HDW-32T exhibited 95.1 % 16S rRNA gene sequence similarity with Nitratireductor basaltis J3T, 94.8 % sequence similarity with Ahrensia kielensis IAM 12618T and <94.5 % with other members of the family Phyllobacteriaceae . In the neighbour-joining, maximum-likelihood and maximum-parsimony trees based on 16S rRNA gene sequences, strain HDW-32T clustered with A. kielensis IAM 12618T. Strain HDW-32T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. Differences in polar lipids, DNA G+C content and other phenotypic properties distinguished strain HDW-32T from A. kielensis JCM 20689T. Strain HDW-32T could also be distinguished from representatives of the genera Nitratireductor and Hoeflea by differences in fatty acids and polar lipids. On the basis of phylogenetic, chemotaxonomic and phenotypic data, strain HDW-32T represents a novel species belonging to a novel genus of the family Phyllobacteriaceae of the class Alphaproteobacteria , for which the name Pseudahrensia aquimaris gen. nov., sp. nov. is proposed.

A novel pink-pigmented, facultatively methylotrophic strain, designated M6-76T, was isolated from glacial foreland soil near Ny-Ålesund, Svalbard Archipelago, Norway. Cells of strain M6-76T were rod-shaped (0.4–0.7×0.8–2.0 µm), Gram-stain-negative, aerobic and motile by a single polar flagellum. Growth occurred at 4–28 °C (optimum 18 °C) and at pH 5–8 (optimum pH 7). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain M6-76T belonged to the family Methylobacteriaceae . The 16S rRNA gene sequence of the novel strain showed 94.6 %, 94.0 % and 93.9 % sequence similarity to those of Methylobacterium salsuginis MRT, Methylobacterium organophilum ATCC 27886T and Microvirga subterranea FaiI4T, respectively. Cells could utilize methanol as the sole source of carbon and energy but not formate. The major respiratory quinone was Q-10. The polar lipids were phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and two unknown polar lipids. The predominant cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and C16 : 0. The DNA G+C content was 67 mol%. The polyphasic data presented in this study indicated that the isolate should be classified as representing a novel species of a new genus within the family Methylobacteriaceae . The name Psychroglaciecola arctica gen. nov., sp. nov. is therefore proposed for the isolate. The type strain of the type species is M6-76T ( = CCTCC AB 2013033T = KACC 17684T).

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).

Two marine bacterial strains, designated S2-4-21T and MT2-5-19, were isolated from two tidal flat sediments of cordgrass Spartina alterniflora and adjacent oyster culture field in Quanzhou bay, China, respectively. Both strains were Gram-staining-negative, rod-shaped, non-flagellated, non-motile, aerobic, had NaCl requirements, and contained carotenoid and flexirubin pigments. The 16S rRNA gene sequence similarity (99.8%), average nucleotide identity value (99.4%) and average amino acid identity (99.3%) between strain S2-4-21T and strain MT2-5-19 strongly supported that they belonged to a single species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2-4-21T and strain MT2-5-19 formed a monophyletic branch affiliated to the family Flavobacteriaceae , sharing similarities of 94.6% with Euzebyella marina CY01T and E. saccharophila 7SM30T, and of 94.1 and 92.8% with E. algicola MEBiC 12267T and Pseudozobellia thermophile DSM 19858T, respectively. Phylogenomic analysis based on the whole genome sequences supported that the two strains formed a distinct monophyletic clade within Flavobacteriaceae members, which was phylogenetically different from the clades of Euzebyella and Pseudozobellia . The major respiratory quinone was menaquinone MK-6. The major fatty acids (>10%) consisted of C15 : 0 iso, C16 : 0, summed feature 9 (C17 : 1 iso ω9c/C16 : 0 10-methyl) and C17 : 0 iso 3-OH. The polar lipid profiles of strain S2-4-21T and strain MT2-5-19 are identical, including phosphatidylethanolamine, four unidentified aminolipids, and four unidentified lipids. The genomic size was 4.9–5.0 Mb with genomic DNA G+C content of 41.5 mol%. Based on the above characteristics, strains S2-4-21T and MT2-5-19 represented a novel species of a novel genus in the family Flavobacteriaceae . Thus, Pareuzebyella sediminis gen. nov. sp. nov. is proposed with type strain S2-4-21T (=MCCC 1K03818T=KCTC 72152T), and another strain MT2-5-19 (=KCTC 72539=MCCC 1K03874).

Gram-negative strains, motile by a single polar flagellum, non-pigmented and with a curved rod-shaped morphology, designated IMCC1826T and IMCC1883, were isolated from a surface seawater sample from the Yellow Sea. The two strains shared 99.9 % 16S rRNA gene sequence similarity and showed 92 % DNA–DNA relatedness, suggesting that they belonged to the same genomic species. Phylogenetic analysis based on 16S rRNA gene sequences showed that the two isolates were related most closely to the type strain of Thalassolituus oleivorans with a sequence similarity of 96.4 % and formed a robust phyletic lineage with T. oleivorans . DNA–DNA relatedness between the two strains and T. oleivorans DSM 14913T was 8.7–11.6 %. A putative alkane hydroxylase (alkB) gene was detected in strain IMCC1826T by PCR, but the amino acid sequence of the gene was distantly related to that of the AlkB homologue of T. oleivorans DSM 14913T. As expected from the presence of the alkB gene, the new strains utilized n-tetradecane and n-hexadecane as a carbon source. The DNA G+C content was 54.6–56.0 mol% and the main isoprenoid quinone detected was Q-9. Polar lipids of strain IMCC1826T included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and amino-group-containing lipids. On the basis of taxonomic data obtained in this study, strains IMCC1826T and IMCC1883 represent a novel species of the genus Thalassolituus , for which the name Thalassolituus marinus sp. nov. is proposed, with IMCC1826T ( = KCTC 23084T = NBRC 107590T) as the type strain.
