Query: NC_017068:2604876 Selenomonas ruminantium subsp. lactilytica TAM6421, complete
Lineage: Selenomonas ruminantium; Selenomonas; Veillonellaceae; Selenomonadales; Firmicutes; Bacteria
General Information: This organism is a member of the normal flora of the sheep rumen. The genus Selenomonas constitutes a group of motile crescent-shaped bacteria and includes species living in the gastrointestinal tracts of animals, in particular, the Ruminants. Despite being Firmicutes they stain Gram-negative and possess a double bilayer. Cells are crescent or bean-shaped with coiled flagella located on the concave surface with an infolding of the cell membrane behind the flagellar attachment point.
Subject: NC_009654:4253431 Marinomonas sp. MWYL1, complete genome
Lineage: Marinomonas; Marinomonas; Oceanospirillaceae; Oceanospirillales; Proteobacteria; Bacteria
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.
