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.

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.

Chryseobacterium Gleum

Strain DCY 63T, isolated from the rhizosphere of ginseng, was a Gram-reaction-negative, strictly aerobic, non-motile, catalase- and oxidase-positive rod. 16S rRNA gene sequence analysis revealed that strain DCY 63T belonged to the genus Chryseobacterium and was closely related to Chryseobacterium indoltheticum LMG 4025T (98.1 %), Chryseobacterium ginsenosidimutans THG 15T (98.0 %) and Chryseobacterium scophthalmum LMG 13028T (97.1 %). The major polar lipids of strain DCY 63T were phosphatidylethanolamine (PE), four unidentified aminolipids and three unidentified polar lipids, and the major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl). The predominant isoprenoid quinone of strain DCY 63T was MK-6 and the G+C content of the genomic DNA was 31.6 mol%. The DNA–DNA relatedness values between strain DCY 63T and C. indoltheticum LMG 4025T, C. ginsenosidimutans THG 15T and C. scophthalmum LMG 13028T were less than 30 %. On the basis of these data, strain DCY 63T is considered to represent a novel species of the genus Chryseobacterium , for which the name Chryseobacterium ginsengisoli sp. nov. is proposed. The type strain is DCY 63T ( = KCTC 23760T = JCM 18019T). An emended description of Chryseobacterium gleum is also proposed.

Emended Description

A novel Gram-staining-negative, strictly aerobic bacterium, designated BS14T, was isolated from a marine tidal flat of the South Sea in Korea. Colonies were opaque, white, smooth and circular on marine agar. Cells were moderately halophilic, non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain BS14T was observed at 5–40 °C (optimum: 30 °C), pH 6.5–9.5 (optimum: 7.0–7.5) and 0–10 % (w/v) NaCl (optimum: 1–1.5 %). The G+C content of the genomic DNA was 61.6 mol%. Strain BS14T contained ubiquinone-10 (Q-10) as the sole respiratory quinone and summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), C18 : 0 3-OH, C10 : 0 3-OH and C18 : 0 as the major fatty acids. The polar lipid pattern comprised phosphatidylethanolamine, diphosphatidylglycerol, an unidentified aminolipid, an unidentified phospholipid and an unidentified polar lipid. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BS14T formed a tight phylogenetic lineage with Defluviimonas denitrificans D9-3T with a bootstrap value of 100 %. The 16S rRNA gene sequence similarity between strain BS14T and D. denitrificans D9-3T was 97.4 % and their DNA–DNA relatedness was 19.1±3.6 %. Based on the phenotypic and genotypic studies, strain BS14T represents a novel species of the genus Defluviimonas , for which the name Defluviimonas aestuarii sp. nov. is proposed. The type strain is BS14T ( = KACC 16442T = JCM 18630T). An emended description of the genus Defluviimonas Foesel et al. 2011 is also proposed.

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.
