An orange, rod-shaped, gliding bacterium, designated strain PSC33T, was isolated from the gut microflora of a mussel collected from Gwangyang Bay, South Sea (Republic of Korea). Cells were Gram-reaction-negative, strictly aerobic, and catalase- and oxidase-positive. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G, C15 : 0 3-OH and iso-C17 : 1ω9c. The only isoprenoid quinone was menaquinone-6 (MK-6). The DNA G+C content of strain PSC33T was 37.9 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain PSC33T formed an evolutionary lineage within the radiation encompassing members of the genus Aquimarina with Aquimarina macrocephali JAMB N27T as its nearest neighbour (96.3 % sequence similarity). A number of phenotypic characteristics distinguished strain PSC33T from recognized members of the genus Aquimarina . On the basis of the data presented in this study, strain PSC33T is considered to represent a novel species of the genus Aquimarina , for which the name Aquimarina mytili sp. nov. is proposed. The type strain is PSC33T ( = KCTC 23302T = JCM 17454T). An emended description of A. macrocephali is also provided.

An orange-coloured and slender rod-shaped bacterium, designated strain PSC32T, was isolated from the gut microflora of a mussel collected from Gwangyang Bay, South Sea (Republic of Korea). Cells were Gram-reaction-negative, strictly aerobic, and catalase- and oxidase-positive. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. The only isoprenoid quinone of strain PSC32T was MK-6 and the DNA G+C content was 36.9 mol%. Phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids were found as major polar lipids. A phylogenetic tree based on 16S rRNA gene sequences showed that strain PSC32T forms an evolutionary lineage within the genus Aquimarina and is closely related to Aquimarina spongiae A6T (97.0 % similarity) and to other members of the genus Aquimarina (94.4–96.5 %). Genomic DNA–DNA relatedness between strain PSC32T and A. spongiae A6T was 40.7 %. A number of phenotypic characteristics distinguished strain PSC32T from described members of the genus Aquimarina . On the basis of the evidence presented in this study, strain PSC32T represents a novel species, for which the name Aquimarina gracilis sp. nov. is proposed. The type strain is PSC32T ( = KCTC 23301T = JCM 17453T). An emended description of Aquimarina spongiae is given.

Emended Description

A Gram-staining-negative, catalase- and oxidase-positive, strictly aerobic, rod-shaped bacterial strain isolated from fresh water in Trabzon, Turkey and designated MK3T was characterized by phenotypic and molecular methods in order to determine its phylogenetic position. On the basis of 16S rRNA gene sequence similarity, strain MK3T was shown to belong to the genus Flavobacterium , being most closely related to Flavobacterium ceti CECT 7184T (93.6 %). Sequence similarity with other species of the genus Flavobacterium with validly published names was less than 91.6 %. Phenotypic and chemotaxonomic data supported the affiliation of strain MK3T to the genus Flavobacterium . The only menaquinone was MK-6; the major fatty acids were iso-C15 : 0 (45.2 %), summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1ω9c; 20.4 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 13.3 %) and the major polar lipids were phosphatidylethanolamine, one unidentified aminophospholipid and two unidentified phospholipids. The G+C content of the genomic DNA was 38.6 mol%. The results of physiological and biochemical tests allowed strain MK3T to be distinguished phenotypically from Flavobacterium ceti CECT 7184T. Strain MK3T, therefore, represents a novel species of the genus Flavobacterium , for which the name Flavobacterium anatoliense sp. nov. is proposed. The type strain is MK3T ( = LMG 26441T = NCCB 100384T). An emended description of Flavobacterium ceti is also proposed.

A light-yellow-coloured bacterium, designated strain PTJT-5T, was isolated from the stem of Smilacina japonica A. Gray collected from Taibai Mountain in Shaanxi Province, north-west China, and was subjected to a taxonomic study by using a polyphasic approach. The novel isolate grew optimally at 25–28 °C and pH 6.0–7.0. Flexirubin-type pigments were produced. Cells were Gram-reaction-negative, strictly aerobic, rod-shaped and non-motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain PTJT-5T was a member of the phylum Bacteroidetes , exhibiting the highest sequence similarity to Lacibacter cauensis NJ-8T (87.7 %). The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 and iso-C17 : 0 3-OH. The only polyamine was homospermidine and the major polar lipid was phosphatidylethanolamine. The only respiratory quinone was MK-7 and the DNA G+C content was 40.3 mol%. Based on the phenotypic, phylogenetic and genotypic data, strain PTJT-5T is considered to represent a novel species of a new genus in the family Chitinophagaceae , for which the name Taibaiella smilacinae gen. nov., sp. nov. is proposed. The type strain of Taibaiella smilacinae is PTJT-5T ( = CCTCC AB 2013017T = KCTC 32316T). An emended description of Flavihumibacter petaseus is also proposed.

A strictly aerobic, Gram-stain-negative bacterium, designated strain No.6T, was isolated from a lichen (Cladonia sp.) collected in Geogeum Island, Korea, and its taxonomic status was established by a polyphasic study. Cells of strain No.6T were non-motile, catalase- and oxidase-positive, non-spore-forming rods. Growth was observed at 15–35 °C (optimum, 25–30 °C), at pH 5.0–10.0 (optimum, pH 6.0–8.0) and with 0–3 % NaCl (optimum, 0–2 %). The predominant cellular fatty acids were summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c, 41.5 %), iso-C15 : 0 (26.7 %) and C16 : 0 (9.6 %), and menaquinone MK-7 was the only respiratory quinone. The G+C content of the genomic DNA of strain No.6T was 36.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain No.6T fell within the evolutionary group encompassed by the genus Sphingobacterium . Levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of recognized Sphingobacterium species ranged from 92.1 to 99.1 %, the highest values being with Sphingobacterium siyangense SY1T (99.1 %) and Sphingobacterium multivorum IAM 14316T (98.5 %). DNA–DNA relatedness between strain No.6T and these two type strains were 32.0 and 5.7 %, respectively. The polar lipids found in strain No.6T were phosphatidylethanolamine, two unidentified phospholipids, three unidentified aminophospholipids, one glycolipid and four unidentified lipids. One unidentified sphingolipid was also found. On the basis of phenotypic and genotypic data, strain No.6T represents a novel species of the genus Sphingobacterium , for which the name Sphingobacterium cladoniae sp. nov. is proposed. The type strain is No.6T ( = KCTC 22613T = JCM 16113T). An emended description of Sphingobacterium siyangense is also proposed.

A Gram-stain-negative bacterium, designated strain PF-30T, was isolated from floodwater of a paddy field in South Korea. Strain PF-30T was found to be a strictly aerobic, motile and pink-pigmented rods which can grow at 25–40 °C (optimum, 28 °C), at pH 5.0–9.0 (optimum pH 7.0) and at salinities of 0.5–3.0 % NaCl (optimum 0.5 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain PF-30T belongs to the genus Elioraea , showing highest sequence similarity to Elioraea tepidiphila TU-7T (97.1%) and less than 91.3 % similarity with other members of the family Acetobacteraceae . The average nucleotide identity (ANI) and DNA–DNA relatedness between the strain PF-30T and E. tepidiphila TU-7T yielded an ANI value of 75.1 % and DNA–DNA relatedness of 11.7±0.7 %, respectively. The major fatty acids were identified as C18 : 0 and C18 : 1 ω7c. The predominant respiratory quinone was identified as Q-10. The DNA G+C content was determined to be 69.9 mol%. The strain PF-30T was observed to produce plant-growth-promoting materials such as indole-3-acetic acid (IAA), siderophore and phytase. On the basis of the results from phylogenetic, chemotaxonomic and phenotypic data, we concluded that strain PF-30T represents a novel species of the genus Elioraea , for which the name Elioraea rosea sp. nov. is proposed. The type strain is PF-30T (=KACC 19985T=NBRC 113984T).
