Ruegeria pomeroyi DSS-3

Ecology and Physiology

A Model Heterotrophic Marine Bacterium

Ruegeria pomeroyi DSS-3 is an α-proteobacterium in the roseobacter clade isolated in 1998 from coastal Georgia seawater by enriching for growth on the organic sulfur compound DMSP (dimethylsulfoniopropionate).

The roseobacter clade is one of about 10 major taxa of marine bacteria that dominate bacterioplankton communities in coastal and open oceans. Unlike most of the major marine groups, R. pomeroyi and its roseobacter relatives are readily cultured from seawater (González and Moran 1997, González et al. 2000, Buchan et al. 2001). R. pomeroyi is serving as a model organism for studies of the biogeochemical, ecological, and physiological strategies of heterotrophic marine bacteria.
