Abstract
We announce the draft genome sequence of Sulfitobacter sp. strain CB2047, a marine bacterium of the Roseobacter clade, isolated from a phytoplankton bloom. The genome encodes pathways for the catabolism of aromatic compounds as well as transformations of carbon monoxide and sulfur species. The strain also encodes a prophage as well as the gene transfer agent (GTA), both of which are prevalent among members of the Rhodobacterales order.
Highlights
Members of the Roseobacter lineage of marine bacteria are abundant in the world’s oceans, metabolically versatile, and play important roles in various marine biogeochemical cycles [1]
CB2047 was isolated during an induced Emiliania huxleyi bloom in Raunefjorden, Norway, by direct plating onto 0.22-m filtered fjord seawater agar plates supplemented with dimethylsulfoniopropionate (DMSP) as the sole carbon source [3]
Genome-wide nucleotide similarity alignments with the ⌽CB2047-A and ⌽CB2047-C genomes showed that the prophage shares 79 and 74% nucleotide identity, respectively
Summary
Members of the Roseobacter lineage of marine bacteria are abundant in the world’s oceans, metabolically versatile, and play important roles in various marine biogeochemical cycles [1]. Members of the Sulfitobacter genus of the Roseobacter clade have been shown to play important roles in sulfur cycling in the ocean, transforming both organic and inorganic forms of the compound [1, 2]. Dimethylsulfoniopropionate (DMSP)producing phytoplankton species, such as the coccolithophorid Emiliania huxleyi, are important sources of organic sulfur in marine waters and documented Roseobacter niches [1].
