The genus Sulfitobacter has been mostly found in marine and hypersaline environments. Members of this genus were observed to be associated with marine microalgae by inducing cell death of algae and degrading of algae-derived dimethylsulfoniopropionate (DMSP). Here we reported the complete genome sequence of strain Sulfitobacter sp. BSw21498 isolated from seawater of Kongsfjorden, an Arctic fjord in Svalbard. The strain contained a circular chromosome of 3,097,372 bp with G+C content of 58.55 mol% and a plasmid of 147,547 bp with G+C content of 56.53 mol%. In particular, a gene for DMSP lyase DddL was found in the genome, rendering Sulfitobacter sp. strain BSw21498 one of the Rhodobacterales bacteria equipped with the potential for DMSP degradation.
该属 Sulfitobacter 主要存在于海洋和高盐环境中。该属的成员通过诱导藻类细胞死亡和降解藻类衍生的二甲基巯基丙酸酯（DMSP）与海洋微藻有关。在这里，我们报道了从斯瓦尔巴群岛 Kongsfjorden 的海水中分离出的 Sulfitobacter sp. BSw21498 菌株的完整基因组序列。该菌株包含一个 3,097,372 bp 的圆形染色体，GC 含量为 58.55 mol%，一个 147,547 bp 的质粒，GC 含量为 56.53 mol%。特别是，在基因组中发现了 DMSP 裂解酶 DddL 的基因，这使得 Sulfitobacter sp. 菌株 BSw21498 成为具有 DMSP 降解潜力的红杆菌目细菌之一。
