Query: NC_010321:2207364 Thermoanaerobacter pseudethanolicus ATCC 33223 chromosome, complete
Lineage: Thermoanaerobacter pseudethanolicus; Thermoanaerobacter; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria
General Information: Thermoanaerobacter ethanolicus was isolated from a hot spring microbial mat in Yellowstone National Park. It is a thermophilic anaerobic bacterium, which ferments a wide range of hexose and pentose sugars, as well as starch and pullulan, to ethanol.
Subject: NC_008043:615049 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.
