Insight into the genome sequence of a sediment-adapted marine bacterium Neptunomonas antarctica S3-22T from Antarctica

Neptunomonas antarctica S3-22(T). was isolated from marine sediment of the Nella Fjord, Antarctica. Here we report the draft genome sequence of N. antarctica, which comprises 4,568,828 bp with a mean G + C content of 45.7%. We found numerous genes related to resistance, motility and chemotaxis, nitrogen metabolism, aromatic compound metabolism and stress response. These metabolic features and related genes revealed genetic basis for the adaptation to the marine sediment environment in Antarctica. The genome sequence of N. antarctica S3-22(T). may also provide further insights into the ecological role of the genus Neptunomonas. (C) 2015 Elsevier B.V. All rights reserved.
