A Gram-stain-negative, aerobic, motile, short rod-shaped, catalase-negative and oxidase-positive bacterium, strain CAU 1568T, was isolated from marine sediment sand sampled at Sido Island in the Republic of Korea. The optimum conditions for growth were at 25?30?°C, at pH 6.5?8.5 and with 0?4.0?% (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain CAU 1568T was a member of the genus Photobacterium with high similarity to Photobacterium salinisoli JCM 30852T (97.7?%), Photobacterium halotolerans KACC 17089T (97.3?%) and Photobacterium galatheae LMG F28894T (97.3?%). The predominant cellular fatty acids were C16?:?0, summed feature 3 (C16?:?1?ω6c and/or C16?:?1?ω7c) and summed feature 8 (C18?:?1?ω7c and/or C18?:?1?ω6c), with Q-8 as the major of isoprenoid quinone. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerols, phosphatidylcholine, phosphatidylethanolamine, phospholipid, two aminophospholipids and three unidentified lipids. The whole genome size of strain CAU 1568T was 4.8?Mb with 50.1?mol% G+C content; including 38 contigs and 4233 protein-coding genes. These taxonomic data support CAU 1568T as representing a novel Photobacterium species, for which the name Photobacterium arenosum sp. nov. is proposed. The type strain of this novel species is CAU 1568T (=KCTC 82404T=MCCC 1K05668T).
