Complete genome sequence of Marinomonas arctica BSI20414, a giant antifreeze protein-producing bacterium isolated from Arctic sea ice

Sea ice in the polar oceans is a dynamic and challenging environment for life to survive, with extreme gradients of temperature, salinity nutrients etc., as well formation crystals. Bacteria surviving sea attract broad attention from academia industry, due fascinating mechanisms adaptation. Here we described complete genome sequence Marinomonas arctica BSI20414, isolated Arctic ice. The strain tolerated high low temperature. Genetic features commonly related adaptation oxidative stress, osmotic stress cold were detected genome. In addition, large adhesion protein containing putative antifreeze (AFP) domain was genome, similar giant AFP MpIBP M. primoryensis. presence could facilitate BSI20414 bind favorable conditions protect it freezing. reported here can provide insights into be explored further biotechnological applications.
