Query: NC_003911:4001094 Silicibacter pomeroyi DSS-3, complete genome Lineage: Ruegeria pomeroyi; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria General Information: Formerly Silicibacter pomeroyi, his marine bacterium is a member of the Roseobacter clade and was isolated off of the coast of Georgia in 1998. Dimethylsulfoniopropionate-degrading bacterium. Capable of degrading the organic sulfur compound DMSP (dimethylsulfoniopropionate) and can metabolize a number of sulfur compounds. DMSP is synthesized by marine algae and the degradation product dimethylsulfide contributes to the global sulfur cycle.

General Information: This strain was isolated from a culture of the dinoflagellate Pfiesteria piscicida CCMP1830 which has been implicated in many large scale algal blooms resulting in increased mortality in fish. The bacteria are attached to the surface of the dinoflagellate and in some ways allow the dinoflagellate to grow as those lacking the bacteria die off. The bacterium also chemotaxes towards the dinoflagellate product DMSP (dimethylsulfoniopropionate) and metabolizes it. DMSP is a major source of sulfur in marine ecosystems and plays a role in the sulfur biogeochemical cycle. The implication is a tight association between these important dinoflagellates and this marine bacterium.
