Seawater, or sea water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every kilogram of seawater has approximately 35 grams (1.2 oz) of dissolved salts. The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about −2 °C (28 °F). The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was −2.6 °C (27.3 °F).
Algibacter is a genus in the phylum Bacteroidota (Bacteria).
Lewinella is a Gram-negative, chemoorganotrophic and aerobic genus from the family Lewinellaceae.
Ponticoccus is a bacterial genus from the family of Propionibacteriaceae.
The Temperatibacteraceae are a family of bacteria.
Oceanihabitans is a genus of marine bacterium in the family Flavobacteriaceae. It contains a single species, O. sediminis. It is aerobic, Gram-negative, rod-shaped, and motile by gliding. O. sediminis produces flexirubin pigments. It is positive for cytochrome c oxidase and catalase. O. sediminis can use glucose, mannose, maltose and adipic acid as sole carbon sources for chemoheterotrophic growth. It is a chemoorganotroph and is chemotaxonomically characterized by the presence of menaquinone 6 (MK-6). The type strain is S9-10T.
Flavivirga aquatica is a Gram-negative, aerobic and slightly alkaliphilic bacterium from the genus of Flavivirga.
