Query: NC_014532:1873169 Halomonas elongata DSM 2581, complete genome Lineage: Halomonas elongata; Halomonas; Halomonadaceae; Oceanospirillales; Proteobacteria; Bacteria General Information: Halomonas elongata DSM 2581 was isolated from a solar salt facility and is halotolerant up to a concentration of 35%. Halomonas elongata is a halophilic bacterium which uses ectoine as its major compatible solute. This organism can both, synthesize and degrade ectoine and is used as industrial ectoine producer.

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.
