Query: NC_014926:295988 Thermovibrio ammonificans HB-1 chromosome, complete genome Lineage: Thermovibrio ammonificans; Thermovibrio; Desulfurobacteriaceae; Desulfurobacteriales; Aquificae; Bacteria General Information: Environment: Deep sea, Fresh water, Hydrothermal vent; Isolation: Walls of an active deep-sea hydrothermal; Temp: Thermophile; Temp: 60 - 80C; Country: Pacific Ocean. This is a thermophilic, anaerobic, chemolithoautotrophic bacterium isolated from the walls of an active deep-sea hydrothermal vent chimney on the East Pacific Rise. This organism grows on mineral salts in the presence of carbon dioxide and hydrogen, reducing nitrate or sulfur to ammonium or hydrogen sulfide, respectively.

General Information: Marinomonas MWYL1 was isolated from the root surface of the salt marsh grass Spartina anglica, growing near the North Norfolk, England village of Stiffkey. The genus Marinomonas comprises a widespread group of g -proteobacteria that exist in coastal waters, and which had been earlier been included in the genus Alteromonas. The interest in Marinomonas MWYL 1 was that it could grow on the betaine molecule Dimethylsulphoniopropionate (DMSP) as sole carbon source and, when it did do, it released large amounts of the gas dimethyl sulphide. DMSP is a compatible solute that is used by many marine phytoplankton and seaweed macroalgae as an osmoticum and an anti-stress compound. In addition, a few known land angiosperms make DMSP and these include certain species of Spartina - hence the choice of these plants as a source for DMSP-degrading bacteria. Indeed, others had shown previously that the DMSP-catabolising bacteria isolated from Spartina root surfaces included Marinomonas strains.
