A Gram-reaction-negative, yellow-pigmented, strictly aerobic bacterium, designated M0116T, was isolated from the sediment of the Mohe Basin in north-east China. Flexirubin-type pigments were produced. Cells were catalase- and oxidase-positive and non-gliding rods. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain M0116T was a member of the family Flavobacteriaceae and was most closely related to members of the genera Empedobacter , Wautersiella and Weeksella with 90.5–91.0 % sequence similarities. The major cellular fatty acids were iso-C15 : 0 and iso-C17 : 0 3-OH. The major respiratory quinone was MK-6 and the major polar lipid was phosphatidylethanolamine. The DNA G+C content was 38.2 mol%. Based on phenotypic, phylogenetic and genotypic data, strain M0116T is considered to represent a novel species of a new genus in the family Flavobacteriaceae , for which the name Moheibacter sediminis gen. nov., sp. nov. is proposed. The type strain is M0116T ( = CGMCC 1.12708T = JCM 19634T). Emended descriptions of Empedobacter brevis , Wautersiella falsenii and Weeksella virosa are also proposed.

Two Gram-stain-negative, yellow-pigmented and strictly aerobic bacteria, designated strains SE-s27T and SE-s28T, were isolated from forest soil. Both strains were non-motile rods that were catalase-positive and oxidase-negative and grew optimally at 25–30 °C, pH 8.0 and with 0 % (w/v) NaCl. Strain SE-s28T produced flexirubin-type pigments, but strain SE-s27T did not produce them. Both strains contained menaquinone-6 as the sole respiratory quinone and phosphatidylethanolamine as a major polar lipid. As the major cellular fatty acids (>10 %), SE-s27T contained iso-C15 : 1 and iso-C15 : 1G, whereas SE-s28T contained iso-C15 : 0 and summed feature 3 comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH. The DNA G+C contents of strains SE-s27T and SE-s28T were 33.1 and 44.3 mol%, respectively. The results of phylogenetic analysis based on 16S rRNA gene sequences revealed that SE-s27T and SE-s28T formed respective distinct phylogenetic lineages within the genus Flavobacterium . Strains SE-s27T and SE-s28T were most closely related to Flavobacterium macrobrachii an-8T and Flavobacterium piscinae ICH-30T with 98.0 and 94.5 % 16S rRNA gene sequence similarities, respectively. In conclusion, strains SE-s27T and SE-s28T represent novel species of the genus Flavobacterium , for which the names Flavobacterium solisilvae sp. nov. and Flavobacterium silvaticum sp. nov. are proposed. The type strains of F. solisilvae and F. silvaticum are SE-s27T (=KACC 18802T=JCM 31544T) and SE-s28T (=KACC 18803T=JCM 31545T), respectively.

A strictly aerobic, Gram-negative, yellow-pigmented, non-spore-forming rod, designated 15C3T, was isolated from aerobic leaf-and-branch compost at EXPO Park in Osaka, Japan. Growth was observed at 9–33 °C (optimum 25 °C) and pH 5.6–7.9 (optimum pH 6.1–7.0). No growth occurred with >2 % (w/v) NaCl. Strain 15C3T reduced nitrate to nitrogen and showed catalase activity but not oxidase activity. The predominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH). The isolate contained phosphatidylethanolamine as the major polar lipid and menaquinone-6 as the major respiratory quinone. The G+C content of the genomic DNA of strain 15C3T was 33.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 15C3T belonged to the genus Flavobacterium and was most closely related to Flavobacterium hercynium WB 4.2-33T (96.9 % sequence similarity). On the basis of phenotypic and phylogenetic distinctiveness, strain 15C3T is considered to represent a novel species in the genus Flavobacterium , for which the name Flavobacterium compostarboris sp. nov. is proposed. The type strain is 15C3T ( = KACC 14224T  = JCM 16527T). Emended descriptions of F. hercynium , Flavobacterium resistens and Flavobacterium johnsoniae are also given.

A Gram-stain-negative, orange-pigmented and strictly aerobic bacterium, designated strain MJ115T, was isolated from seawater in Pohang, South Korea. Cells were non-motile rods and showed positive reactions for catalase and oxidase tests. Growth of strain MJ115T was observed at 4–35 °C (optimum, 30 °C), pH 6.0–7.0 (optimum, pH 6.5) and in the presence of 0–8.0 % (w/v) NaCl (optimum, 2.0%). Strain MJ115T contained iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 1  ω9c, C17 : 0 2-OH, iso-C16 : 0 3-OH, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) as major cellular fatty acids and menaquinone-6 as the major respiratory quinone. Phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids were detected as major polar lipids. The G+C content of the genomic DNA was 40.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ115T formed a phyletic lineage with Nonlabens marinus S1-08T, Nonlabens agnitus JC2678T and Nonlabens antarcticus AKS 622T within the genus Nonlabens . Strain MJ115T was also most closely related to N. marinus S1-08T, N. agnitus JC2678T and N. antarcticus AKS 622T with 96.5, 96.4 and 96.0 % 16S rRNA sequence similarities, respectively. Here it is proposed that strain MJ115T represents a new species of the genus Nonlabens , for which the name Nonlabens ponticola sp. nov. is proposed. The type strain is MJ115T (=KCTC 72237T=NBRC 113963T). In addition, the comparison of the whole genome sequences and phenotypic features suggested that Nonlabens tegetincola and Nonlabens sediminis belong to the same species. Therefore, it is proposed that N. sediminis is reclassified as a later heterotypic synonym of N. tegetincola .

A Gram-staining-negative, chemoheterotrophic, yellow-pigmented, gliding, catalase- and oxidase-positive, flexirubin-negative, strictly aerobic bacterium, designated strain IMCC9485T, was isolated from a seawater sample collected from the Arctic Ocean. Optimal growth of strain IMCC9485T was observed at 25 °C, pH 7–8 and in the presence of 1.5–2.5 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMCC9485T belonged to the genus Formosa and was closely related to Formosa algae KCTC 12364T (98.2 %) and Formosa agariphila KCTC 12365T (98.0 %). DNA–DNA relatedness between the new isolate and F. algae and F. agariphila was far lower than 70 %, which indicated that strain IMCC9485T is a novel genomic species of the genus Formosa . The major fatty acids (>10 %) were iso-C15 : 1G (13.7 %), C16 : 1ω7c and/or C16 : 1ω6c (13.4 %) and iso-C15 : 0 (12.3 %). The G+C content of the genomic DNA was 37.6 mol%. Strain IMCC9485T contained menaquinone-6 (MK-6) as the respiratory quinone and phosphatidylethanolamine, unknown aminophospholipids and unknown polar lipids as polar lipid constituents. On the basis of phylogenetic analyses and differential phenotypic characteristics, it is suggested that strain IMCC9485T ( = KACC 17484T = KCCM 42937T = NBRC 106080T) be assigned to the genus Formosa as the type strain of a novel species, for which the name Formosa arctica sp. nov. is proposed.
