Complete genome of Pseudomonas sp. DMSP-1 isolated from the Arctic seawater of Kongsfjorden, Svalbard

Authors: Zeng, Yin-Xin and Zhang, Yi-He and Qu, Jiang-Yong

The genus Pseudomonas is highly metabolically diverse and has colonized a wide range of ecological niches. The strain Pseudomonas sp. DMSP-1 was isolated from Arctic seawater (Kongsfjorden, Svalbard) using dimethylsulfoniopropionate (DMSP) as the sole carbon source. To better understand its role in the Arctic coastal ecosystem, the genome of Pseudomonas sp. strain DMSP-1 was completely sequenced. The genome contained a circular chromosome of 6,282,445?bp with an average GC content of 60.01?mol%. A total of 5510 protein coding genes, 70 tRNA genes and 19 rRNA genes were obtained. However, no genes encoding known enzymes associated with DMSP catabolism were identified in the genome, suggesting that novel DMSP degradation genes might exist in Pseudomonas sp. strain DMSP-1.
