A novel marine flavobacterial species, designated 3KA7-17 T , was isolated from the hard coral Acropora formosa D. collected in Japan. The strain was pale-orange pigmented, Gram-stain negative, strictly aerobic, coccus shaped, and non-motile. Preliminary analysis based on the 16S rRNA gene sequence revealed an affiliation with the family Flavobacteriaceae of the phylum Bacteroidetes, and it had the greatest sequence similarity (96.0%) to Seonamhaeicola algicola Gy8 T . The DNA G + C content was 34.3 mol%. MK-6 was the major menaquinone, with iso-C15:1 H and/or C13:0 3-OH (24.3%), iso-C15:0 (19.5%), iso-C15:0 3-OH (14.2%), and iso-C17:0 3-OH (15.9%) as the main (> 10%) cellular fatty acids. The major polar lipid profile consisted of phosphatidylethanolamine, two unidentified aminolipids, and two unidentified lipids. Based on distinct phylogenetic and phenotypic evidence, the strain represents a novel species of the genus Seonamhaeicola, for which the name Seonamhaeicola acroporae sp. nov. is proposed and the type strain is 3KA7-17 T (= KCTC 62713 T = NBRC 113410 T ).

“…Some members of the family Flavobacteriaceae are adept at utilizing macromolecules such as polysaccharides [9]. Genome analyses have shown an abundance genes coding for proteases, glycohydrolases and polysaccharide lyases in many of them, indicating that the family plays a very important role in the carbon cycle [10–12]. In our study, we obtained the novel isolate, Dm15 T , from a brown alga in coastal waters, which had the same features as above.…”

A Gram-stain-negative, aerobic, yellow, non-motile, rod-shaped and alginate-degrading bacterium, designated Dm15T, was isolated from marine alga collected in Weihai, PR China. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Dm15T represents a distinct line of the family Flavobacteriaceae . Strain Dm15T had the highest 16S rRNA gene sequence similarity to its closest phylogenetic neighbour Arcticiflavibacter luteus (96.7 %) and 93.7–96.4 % sequence similarity to other phylogenetic neighbours ( Bizionia paragorgiae , Winogradskyella thalassocola , Ichthyenterobacterium magnum , Psychroserpens burtonensis and Arcticiflavibacter luteus ) in the family Flavobacteriaceae . The novel isolate was able to grow at 10–40 °C (optimum, 30–33 °C), pH 7.0–9.0 (optimum, pH 7.0–7.5) and with 0.5–6.0 % NaCl (optimum 2.0–3.0 %, w/v). It could grow at 40 °C, and degrade alginate and cellulose, which were different from the neighbour genera. The draft genome consisted of 3395 genes with a total length of 3 798 431 bp and 34.1mol% G+C content. Especially, there were some specific genes coding for cellulase and alginate lyase, which provided a basis for the above phenotypic characteristics. The strain's genome sequence showed 71.1–80.2 % average amino acid identity values and 71.8–77.7 % average nucleotide identity values compared to the type strains of related genera within the family Flavobacteriaceae . It shared digital DNA–DNA hybridization identity of 19.8 and 20.9 % with I. magnum and A. luteus , respectively. The sole menaquinone was MK-6. The major fatty acids were iso-C15 : 0 and iso-C15 : 1 G. The polar lipids included six unidentified polar lipids, four unidentified aminolipids and phosphatidylethanolamine. Based on the results of phenotypic, chemotaxonomic and phylogenetic analyses, strain Dm15T represents a novel species of a new genus in the family Flavobacteriaceae , phylum Bacteroidetes , for which the name Flavihalobacter algicola gen. nov., sp. nov. is proposed. The type strain is Dm15T (KCTC 42256T=CICC 23815T).
