Authors: Meng, Yingying and Zhang, Zheng and Li, Jiang and Lv, Yingtao and Lin, Xuezheng

The general features and genome characteristics of the denitrifying bacterium Marinobacter sp. Arc7-DN-1, isolated from Arctic Ocean sediment, are described. Marinobacter sp. Arc7-DN-1 uses NO3- or NH4+ as the sole nitrogen source to grow at low temperatures. The strain can grow at a wide range of temperatures (0–30?°C) and NaCl concentration (15–90‰). The genome has one circular chromosome of 4,300,456?bp (57.64?mol%?G?+?C content), consisting of 4012 coding genes, including 50 tRNAs and three rRNA operons as 16S-23S-5S rRNA. On the basis of the KEGG analysis, strain Arc7-DN-1 encodes 43 proteins related to nitrogen metabolism, including a complete denitrifying pathway and an assimilatory nitrate reduction pathway.
