Complete Genome Sequence of Nitrogen-Fixing Marine Bacterium Vibrio diazotrophicus YJK1 Isolated from Salt Marsh in Jeju, Republic of Korea

Species of the genus Vibrio are marine bacteria characterized by rapid growth and high metabolic flexibility [1].Among them, Vibrio diazotrophicus, first described in 1982, is a Gram-negative marine non-cyanobacterial diazotroph capable of nitrogen fixation [2].Biological nitrogen fixation plays a critical role in marine ecosystems by supplying bioavailable nitrogen to plankton communities, thereby influencing primary production [3].V. diazotrophicus YJK1 was isolated from a salt marsh located on Biyangdo Island, Jeju, Republic of Korea.The YJK1 strain was initially screened on LB3 high-salt medium (5 g/l of yeast extract, 10 g/l of tryptone, and 30 g/l of sodium chloride) at 30℃ for 24 h, followed
