[6] Nitratidesulfovibrio vulgaris is a sulfate-reducing bacterium (SRB) that plays an important role in cycling elements.

[9] When Nitratidesulfovibrio vulgaris is exposed to increased salinity, it responds with the upregulation of chemotaxis genes and the downregulation of flagellar biosynthesis.

[6] Another common response is the accumulation of neutral, polar, small molecules that serve as osmoprotectants, such as glycine betaine (GB) and proline.

[6] This microbe also responds to increased salinity by using its efflux systems to pump excess salt ions out of the cell.

[6] One notable characteristic of Nitratidesulfovibrio vulgaris is that it changes to have a more elongated structure when exposed to high salinity, possibly caused by inhibition of DNA replication.
