A Gram-stain-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterial strain, BS-B2T, which was isolated from a tidal flat sediment at Boseong in South Korea, was characterized taxonomically. Strain BS-B2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. The novel strain exhibited highest 16S rRNA gene sequence similarity (97.4 %) to Marivita geojedonensis DPG-138T. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain BS-B2T is closely related to Primorskyibacter sedentarius KMM 9018T, showing 96.5 % sequence similarity. Strain BS-B2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the predominant fatty acid. The polar lipid profile of strain BS-B2T comprised phosphatidylcholine, phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid as major components, and differentiated it from the type strains of P. sedentarius and M. geojedonensis . The DNA G+C content of strain BS-B2T was 62.2 mol%. Differential phenotypic properties, together with the phylogenetic and chemotaxonomic data, demonstrated that strain BS-B2T can be distinguished from phylogenetically related genera as well as P. sedentarius and M. geojedonensis . On the basis of the data presented, strain BS-B2T is considered to represent a novel species of a new genus, for which the name Aestuariivita boseongensis gen. nov., sp. nov. is proposed. The type strain of Aestuariivita boseongensis is BS-B2T ( = KCTC 42052T = CECT 8532T).

Sequencing of the amplified 16S rRNA gene and phylogenetic analysis were performed as described by Yoon et al (2003). Isoprenoid quinones were extracted according to the method of Komagata & Suzuki (1987) and analysed using reversed-phase HPLC and a YMC ODS-A (25064.6 mm) column.…”

A strain of Gram-staining-negative, aerobic, non-flagellated, non-gliding and rod-shaped bacteria, designated WS-MY3 T , was isolated from a brown algae reservoir in South Korea. Strain WS-MY3 T grew optimally at 25 6C, at pH 7.0-8.0 and in the presence of 2.0-3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain WS-MY3 T fell within the cluster comprising the type strains of species of the genus Formosa, clustering coherently with the type strains of Formosa agariphila and Formosa algae. It exhibited 16S rRNA gene sequence similarity values of 98.7, 97.9 and 96.8 % to the type strains of F. agariphila, F. algae and Formosa spongicola, respectively. Strain WS-MY3 T contained MK-6 as the predominant menaquinone and iso-C 15 : 0 , iso-C 16 : 0 3-OH, iso-C 15 : 1 G and summed feature 3 (C 16 : 1 v7c and/or C 16 : 1 v6c) as the major fatty acids. The major polar lipids of strain WS-MY3 T were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain WS-MY3 T was 37.3 mol% and its DNA-DNA relatedness values with F. agariphila KCTC 12365 T and F. algae KCTC 12364 T were 23 % and 17 %, respectively. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WS-MY3 T is separate from the three recognized species of the genus Formosa. On the basis of the data presented, strain WS-MY3 T is considered to represent a novel species of the genus Formosa, for which the name Formosa undariae sp. nov. is proposed. The type strain is WS-MY3 T (5KCTC 32328 T 5CECT 8286 T ).

A Gram-stain-negative, non-flagellated, non-gliding and rod-shaped bacterial strain, designated KEM-8 T , was isolated from seawater in the Korean peninsula. Strain KEM-8 T was found to grow optimally at pH 7.0-8.0, at 30 8C and in the presence of 2-3 % (w/v) NaCl. A neighbourjoining phylogenetic tree based on 16S rRNA gene sequences showed that strain KEM-8 T falls within the clade comprising species of the genus Gaetbulibacter, clustering with the type strains of Gaetbulibacter marinus and Gaetbulibacter lutimaris with which it exhibits 98.4 and 97.2 % 16S rRNA gene sequence similarity, respectively. Sequence similarities to Gaetbulibacter saemankumensis SMK-12 T and Gaetbulibacter aestuarii KCTC 23303 T were 95.4 and 95.2 %, respectively. Strain KEM-8 T was found to contain MK-6 as the predominant menaquinone and iso-C 15 : 0 , iso-C 17 : 0 3-OH, iso-C 16 : 0 3-OH and iso-C 15 : 1 G as the major fatty acids. The major polar lipids were identified as phosphatidylethanolamine and an unidentified lipid. The DNA G+C content of strain KEM-8 T was 36.0 mol% and mean DNA-DNA relatedness values with G. marinus KCTC 23046 T and G. lutimaris D1-y4 T were 27.6¡0.9 and 10.3¡1.4 %, respectively. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain KEM-8 T is distinguishable from species of the genus Gaetbulibacter with validly published names. On the basis of the data presented, strain KEM-8 T represents a novel species of the genus Gaetbulibacter, for which the name Gaetbulibacter aquiaggeris sp. nov. is proposed. The type strain is KEM-8 T (5KCTC 42198 T 5NBRC 110553 T ).The genus Gaetbulibacter, a member of the family Flavobacteriaceae (phylum Bacteroidetes), was established by Jung et al. (2005) with the description of Gaetbulibacter saemankumensis, isolated from seawater of the Yellow Sea in South Korea. Subsequently, three further species of the genus, Gaetbulibacter marinus, Gaetbulibacter aestuarii and Gaetbulibacter lutimaris, were described from marine environments in Korea (Yang & Cho, 2008;Park et al., 2012;Yoon et al., 2013).The standard dilution plating technique was used for isolation of bacterial strains from seawater from Geumgang Estuary Bank (368 009 48.960 N 1268 449 23.9990 E) in South Korea. Strain KEM-8 T was isolated on marine agar 2216 (MA; Becton Dickinson) at 25 8C and cultivated routinely on MA at 30 8C. Strain KEM-8 T was maintained on MA at 4 8C for short-term preservation and as a glycerol suspension (20 %, w/v in distilled water) at 280 8C for long-term preservation. G. marinus KCTC 23046 T and G. lutimaris D1-y4 T were used as reference strains for DNA-DNA hybridization, phenotypic characterization (except for some characters) and fatty acid analysis. G. saemankumensis (type species of the genus Gaetbulibacter) SMK-12 T and G. aestuarii KCTC 23303 T were used as reference strains for phenotypic characterization (except for some characters) and fatty acid analysis. G. saemankumensis SMK-12 T and G. lutimaris D1-y4 T were obta...
