gen. nov., sp. nov., a novel member of the family , isolated from sea sand.

A Gram-negative, non-motile, and creamy-white coloured bacterium, designated CAU 1616, was isolated from sea sand collected at Ayajin Beach, Goseong-gun, Republic of Korea. The bacterium was found to grow optimally at 37 °C, pH 8.0-8.5, and with 1-5 % (w/v) NaCl. Phylogenetic analyses based on the 16S rRNA gene sequences placed strain CAU 1616 within the order . The highest 16S rRNA gene sequence similarity was to YIM D812 (94.1 %), YIM D82 (93.7 %), BA45AL (93.6 %) and HHTR 118 (92.3 %). Comparing strain CAU 1616 with closely related species ( YIM D812 and YIM D82), the average nucleotide identity based on blast+ values were 69.7-69.8 %, the average amino acid identity values were 61.3-61.4 %, and the digital DNA-DNA hybridization values were 18.4-18.5 %. The assembled draft genome of strain CAU 1616 had 29 contigs with an N50 value of 385.8 kbp, a total length of 3 490 371 bp, and a DNA G+C content of 65.1 mol%. The predominant cellular fatty acids were C 2-OH, C cyclo 8, and summed feature 8 (C 6 and/or C 7). The major respiratory quinone was Q-10. Based on phenotypic, phylogenetic, and chemotaxonomic evidence, strain CAU 1616 represents a novel genus in the family , for which the name gen. nov., sp. nov. is proposed. The type strain is CAU 1616 (=KCTC 82428=MCCC 1K06089).
