ABSTRACT
A Gram-negative, non-motile, and creamy-white coloured bacterium, designated CAU 1616T, was isolated from sea sand collected at Ayajin Beach, Goseong-gun, Republic of Korea. The bacterium was found to grow optimally at 37â°C, pH 8.0-8.5, and with 1-5â% (w/v) NaCl. Phylogenetic analyses based on the 16S rRNA gene sequences placed strain CAU 1616T within the order Rhodospirillales. The highest 16S rRNA gene sequence similarity was to Fodinicurvata fenggangensis YIM D812T (94.1â%), Fodinicurvata sediminis YIM D82T (93.7â%), Fodinicurvata halophila BA45ALT (93.6â%) and Algihabitans albus HHTR 118T (92.3â%). Comparing strain CAU 1616T with closely related species (Fodinicurvata fenggangensis YIM D812T and Fodinicurvata sediminis YIM D82T), the average nucleotide identity based on blast+ values were 69.7-69.8â%, the average amino acid identity values were 61.3-61.4â%, and the digital DNA-DNA hybridization values were 18.4-18.5â%. The assembled draft genome of strain CAU 1616T had 29 contigs with an N50 value of 385.8 kbp, a total length of 3â490â371 bp, and a DNA G+C content of 65.1âmol%. The predominant cellular fatty acids were C18ââ1 2-OH, C19ââ0 cyclo ω8c, and summed feature 8 (C18ââ1 ω6c and/or C18ââ1 ω7c). The major respiratory quinone was Q-10. Based on phenotypic, phylogenetic, and chemotaxonomic evidence, strain CAU 1616T represents a novel genus in the family Rhodovibrionaceae, for which the name Aquibaculum arenosum gen. nov., sp. nov. is proposed. The type strain is CAU 1616T (=KCTC 82428T=MCCC 1K06089T).
