摘要

A marine psychrophilic bacterium Paenisporosarcina antarctica CGMCC 1.6503(T) (= JCM 14646(T)) was isolated off King George Island, Antarctica (62 degrees 13'31 '' S 58 degrees 57'08 '' W). In this study, we report the complete genome sequence of Paenisporosarcina antarctica, which is comprised of 3,972,524 bp with a mean G + C content of 37.0%. By gene function and metabolic pathway analyses, studies showed that strain CGMCC 1.6503(T) encodes a series of genes related to cold adaptation, including encoding fatty acid desaturases, dioxygenases, antifreeze proteins and cold shock proteins, and possesses several two-component regulatory systems, which could assist this strain in responding to the cold stress, the oxygen stress and the osmotic stress in Antarctica. The complete genome sequence of P. antarctica may provide further insights into the genetic mechanism of cold adaptation for Antarctic marine bacteria.
