Draft Genome Sequences of Idiomarina abyssalis Strain KJE, Marinobacter salarius Strain NP2017, and Marinobacter salarius Strain AT3901, Isolated from Deep-Sea Sediment near the Western Flank of the Mid-Atlantic Ridge.

We report the draft genomes of environmental cultures collected from shallow sediment from the western flank of the Mid-Atlantic Ridge. The isolates were most closely related to Idiomarina abyssalis strain KJE (100% complete), Marinobacter salarius strain NP2017 (97.6% complete), and Marinobacter salarius strain AT3901 (98.4% complete). Isolates identified as an Idiomarina species possess complete nitrite oxidation and reduction pathways, and isolates identified as a Marinobacter species possess complete dissimilatory nitrate reduction pathways.
