Genomic insight into Aquimarina longa SW024T: its ultra-oligotrophic adapting mechanisms and biogeochemical functions

摘要

BackgroundSouth Pacific Gyre (SPG) is the largest and clearest gyre in the world, where the concentration of surface chlorophyll a and primary production are extremely low. Aquimarina longa SW024^T was isolated from surface water of the SPG center. To understand how this bacterium could survive in this ultra-oligotrophic oceanic environment and its function in biogeochemical cycle, we sequenced the genome of A. longa SW024^T and performed extensive genomic analyses.
