Query: NC_012029:1525929 Halorubrum lacusprofundi ATCC 49239 chromosome 1, complete genome Lineage: Halorubrum lacusprofundi; Halorubrum; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea General Information: Formerly Halobacterium lacusprofundi, this organism is an extremely halophilic archaeon isolated from Deep Lake, Antarctica. Extremely halophilic archaeon isolated from the Antarctic. Halorubrum lacusprofundi is a red pigmented halophilic archaeon which has been found in hypersaline marine enviornments. Originally thought to be a psychrophile, further research determined that the optimum temperature for growth for Halorubrum lacusprofundi was from 31 - 37 degrees C.

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.
