Abstract

Members of the genus Pseudomonas have been frequently isolated from the marine environment, indicating their ecological role in native habitats. One bacterial strain, Pseudomonas sp. BSw22131, was isolated from seawater in Kongsfjorden, Svalbard. The bacterium can grow with algae-derived dimethylsulfoniopropionate (DMSP) as the sole carbon source. Here, we sequenced the complete genome of strain BSw22131, which contained a single circular chromosome of 5,739,290 (G + C content of 58.23 mol%) without any plasmids. A total of 5362 protein-coding genes, 65 tRNA genes, and 16 rRNA genes were obtained. Genome sequence analysis revealed that strain BSw22131 was not only a potential novel species of the genus Pseudomonas but also different from Pseudomonas sp. DMSP-1 that was isolated from the same habitat and also utilized DMSP as the sole carbon source for growth. The results can be helpful for understanding the catabolism of the genus Pseudomonas in sulfur cycling in the Arctic fjord ecosystem.

以二甲基磺酰丙酸(DMSP)为唯一碳源生长的新型海洋假单胞菌BSw22131的全基因组序列

假单胞菌属的成员经常从海洋环境中分离出来，表明它们在原生栖息地中的生态作用。从斯瓦尔巴群岛Kongsfjorden海水中分离到1株假单胞菌BSw22131。该细菌可以以藻类衍生的二甲基磺酰丙酸(DMSP)作为唯一的碳源生长。本研究对菌株BSw22131的全基因组进行了测序，发现该菌株的单环染色体长度为5,739,290 (G + C含量为58.23 mol%)，不含质粒。共获得蛋白编码基因5362个，tRNA基因65个，rRNA基因16个。基因组序列分析表明，菌株BSw22131不仅是假单胞菌属的潜在新种，而且与假单胞菌sp. DMSP-1不同，后者分离自同一生境，以DMSP为唯一碳源生长。研究结果有助于了解假单胞菌属在北极峡湾生态系统硫循环中的分解代谢。

期刊介绍： The journal publishes papers on all functional and evolutionary aspects of genes, chromatin, chromosomes and (meta)genomes of marine (and freshwater) organisms. It deals with new genome-enabled insights into the broader framework of environmental science. Topics within the scope of this journal include: • Population genomics and ecology • Evolutionary and developmental genomics • Comparative genomics • Metagenomics • Environmental genomics • Systems biology More specific topics include: geographic and phylogenomic characterization of aquatic organisms, metabolic capacities and pathways of organisms and communities, biogeochemical cycles, genomics and integrative approaches applied to microbial ecology including (meta)transcriptomics and (meta)proteomics, tracking of infectious diseases, environmental stress, global climate change and ecosystem modelling.
