Query: NC_016745:2229271 Oceanimonas sp. GK1 chromosome, complete genome
Lineage: Oceanimonas; Oceanimonas; Aeromonadaceae; Aeromonadales; Proteobacteria; Bacteria
General Information: Oceanimonas sp. (strain GK1) is an aerobic, marine halotolerant, Gram-negative bacterium isolated from Gavkhouni Wetland in Iran. It is a motile bacterium which can tolerate up to 12% NaCl. It grows at tempatures between 10 to 45 degrees C with an optimum at 35 degrees C and at pH between 6 to 10 with an optimum at 8. Oceanimonas sp. produces large amounts of poly-hydroxybutyrate (PHB) as a carbon and energy reservoir under unbalanced growth conditions. PHB is a biodegradable and renewable biosynthetic polymer which can be used in medicine, tissue engineering, and packaging materials.
Subject: NC_008044:136844 Silicibacter sp. TM1040, complete genome
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.
