title: Halocynthiibacter arcticussp. nov., isolated from Arctic marine sediment.
abstract: A Gram-staining-negative, oxidase- and catalase-positive, non-motile, aerobic and rod-shaped bacterium producing white colonies, PAMC 20958T, was isolated from a marine sediment of the Arctic. PAMC 20958Tgrew at 10-27 °C (optimally at 21 °C), at pH 5.5-9.5 (optimally at pH 7.0-7.5) and in the presence of 0.5-7.5 % (w/v) (optimally at 2.0 %) NaCl. PAMC 20958Tshowed 97.5 % 16S rRNA gene sequence similarity withHalocynthiibacter namhaensisKCTC 32362Tand formed a robust phylogenetic clade with this species. The average nucleotide identity value between strain PAMC 20958TandH. namhaensisKCTC 32362Twas 79.7 % and the genome-to-genome distance was 13.0 % on average. The genomic DNA G+C content calculated from the genome sequence was 53.2 mol%. The major fatty acids were C18 : 1ω7cand/or C18 : 1ω6c. The major respiratory isoprenoid quinone was ubiquinone-10 (Q-10) and major polar lipids were phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid and two unidentified lipids. On the basis of phylogenetic analysis and genotypic and phenotypic data obtained in this study, it is concluded that strain PAMC 20958T( = KCTC 42129T= JCM 30530T) represents the type strain of a novel species of the genusHalocynthiibacter,for which the nameHalocynthiibacter arcticussp. nov. is proposed.
