Marinomonas sp. MWYL1

Names Marinomonas sp. MWYL1
Accession numbers NC_009654
Background 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 gamma-proteobacteria that exist in coastal waters, and which had been earlier been included in the genus Alteromonas. Some Marinomonas strains are pigmented strains due to melanin and some produce metabolites that may be of biotechnological value . However, the interest in Marinomonas MWYL1 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. The catabolism of DMSP is of major importance, for several reasons. First, it represents a colossal biotransformation of marine sulfur and carbon. Secondly, the process can lead to the production of DMS, much of is released into the atmosphere, where it can be oxidised to form products that act as cloud condensation nuclei. These are responsible for forming much of the cloud cover over the oceans, on such a scale that the light incidence on the Earth and hence the climate is significantly affected . The DMS-dependent synthesis of the climate-changing gas DMS is likely determined by genes that are subject to horizontal gene transfer. (EBI Integr8)
