Query: NC_016052:2201211 Tetragenococcus halophilus NBRC 12172, complete genome
Lineage: Tetragenococcus halophilus; Tetragenococcus; Enterococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Tetragenococcus halophilus is a gram-positive lactic acid bacterium which flourishes in extreme salt environments. It plays a role in halophilic fermentation processes such as the production of soy sauce and fish sauce.
Subject: NC_008043:499399 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.
