A Gram-stain-negative, rod-shaped, non-flagellated, non-gliding, aerobic bacterial strain, designated LPB0138T, was isolated from a marine spoon worm (Urechis unicinctus). The strain LPB0138T contains a circular chromosome of 3.43 Mb with a DNA G+C content of 30.4 mol%. The genome includes 2987 protein-coding genes and two copies of rRNA operons. The 16S rRNA gene sequence analysis showed that the isolate occurred within a clade containing only members of the family Flavobacteriaceae . The highest sequence similarity was observed with the genus Lutibacter (93.0–94.3 %), but the phylogenetic leaf of the new isolate did not belong to any of the genera known in the family Flavobacteriaceae . The low sequence similarity and the phylogenetic tree topology implied the novel generic status of the new isolate. The phenotypic properties of the strain LPB0138T also differentiated this isolate from its neighbour genera by showing a distinctive fatty acid composition, unique polar lipids profile, and low DNA G+C content. The LPB0138T strain contained menaquinone 6 as the isoprenoid quinone; iso-C15 : 1 G, iso-C15 : 0, iso-C15 : 0 3-OH, and iso-C17 : 0 3-OH as the major fatty acids; and phosphatidylethanolamine, unidentified aminophospholipids, unidentified aminolipids, and unidentified lipids as the major polar lipids. Based on the polyphasic taxonomic data obtained, the LPB0138T strain is considered to represent a novel species in a novel genus of the family Flavobacteriaceae, for which the name Urechidicola croceus gen. nov., sp. nov. was proposed. The type strain is LPB0138T (=KACC 18889T;=JCM 31563T).

A Gram-stain-negative, light pink-coloured, rod-shaped, flagellated and facultative anaerobic bacterial strain, designated MT2928T, was isolated from deep-sea sediment collected from the Mariana Trench. Growth of strain MT2928T occurred optimally at 28 °C, pH 8.0–9.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain MT2928T belongs to the genus Pontivivens and has the highest sequence similarity to Pontivivens insulae GYSW-23T (96.6 %). Genomic analysis indicated that strain MT2928T contains a circular chromosome of 4 199 362 bp with G+C content of 67.2 mol%. The strain did not produce bacteriochlorophyll a, but produced carotenoid. The predominant respiratory quinone of MT2928T was ubiquinone-10. The polar lipids of MT2928T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified lipids and two unidentified phospholipids. The major fatty acids of strain MT2928T contained summed feature 8 (C18 : 1  ω7c or/and C18 : 1  ω6c), C18 : 0 and summed feature 2 (iso-C16 : 1 I and/or C14 : 0 3-OH). On the basis of phylogenetic, physiological, biochemical and other phenotypic properties, strain MT2928T represents a novel species of the genus Pontivivens , and the name Pontivivens ytuae sp. nov. is proposed with the type species MT2928T (=MCCC 1K05575T=JCM 34320T).

Gram-negative, rod-shaped, oxidase-negative, facultatively anaerobic, yellow–orange-pigmented and motile bacterial strains, designated 8N4T, 9N2 and 10N3, were isolated from flower nectar of Amygdalus communis (almond) and Citrus paradisi (grapefruit). The 16S rRNA gene sequences of the strains shared highest sequence similarity of 97.0 % with that of Phaseolibacter flectens ATCC 12775T and lower similarity with sequences from other type strains of genera of the Enterobacteriaceae . A polyphasic approach that included determination of phenotypic properties and phylogenetic analysis based on 16S rRNA, gyrB, rpoB and atpD gene sequences supported the classification of strains 8N4T, 9N2 and 10N3 within a novel species in a novel genus in the family Enterobacteriaceae . Strain 8N4T, and the reference strains of the novel species, grew at 4–35 °C (optimum, 28–30 °C), with 0–5.0 % NaCl (optimum, 3 % NaCl) and with 0–60 % sucrose (optimum, 10–25 % sucrose). Their major cellular fatty acids were C16 : 0, C17 : 0 cyclo, C18 : 1ω7c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The DNA G+C content of strain 8N4T was 46.8 mol%. On the basis of phenotypic properties and phylogenetic distinctiveness, the floral nectar isolates are classified within a novel species in a new genus in the family Enterobacteriaceae , for which the name Rosenbergiella nectarea 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 Gram-stain-negative, aerobic, short rod-shaped, motile, brownish-coloured bacterium, termed strain LPB0137T, was isolated from a squid. Its cells could grow weakly on marine agar 2216 with 0.04 % 2,3,5-triphenyl tetrazolium chloride (TTC). Each cell of strain LPB0137T has a circular chromosome with a length of 2.87 Mb and 27.7 mol% DNA G+C content. The genome includes 2698 protein-coding genes and six rRNA operons. In 16S rRNA gene sequence trees, strain LPB0137T formed a robust monophyletic clade with Poseidonibacter antarcticus SM1702T with a sequence similarity of 98.3 %. However, the average nucleotide identity and in silico DNA–DNA hybridization values between the two type strains were low (83.9 and 28.1 %, respectively). The overall phenotypic and genomic features of strain LPB0137T supported its assignment to the genus Poseidonibacter . However, the relatively low gene and genome sequence similarity between this strain and other type strains of the genus Poseidonibacter and several enzymatic characteristics indicated the taxonomic novelty of the isolated strain as a new member of the genus Poseidonibacter . Therefore, based on the phylogenetic and phenotypic characteristics of LPB0137T, we proposed a novel species of the genus Poseidonibacter for it, with the name Poseidonibacter parvus sp. nov. The type strain of this new species is thus LPB0137T (=KACC 18888T=JCM 31548T).
