Query: NC_008043:167108 Silicibacter sp. TM1040 mega plasmid, complete sequence

Lineage: Ruegeria; Ruegeria; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria

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.

Subject: NC_015707:1911431 Thermotoga thermarum DSM 5069 chromosome, complete genome

Lineage: Thermotoga thermarum; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria

General Information: Country: Djibouti; Isolation: Continental solfataric spring; Africa; Temp: Hyperthermophile; Temp: 80C. This organism, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Preliminary sequencing of Thermotogales genomes has identified extensive horizontal gene transfer between these organisms and the Archaea. Thermotoga thermarum does not grow at high salt concentrations (>0.6% NaCL). This organism also produces heat stable enzymes such as endoxylanase, beta xylosidase and alpha arabinofuranosidase which may have commercial uses.
