Organic compatible solutes of halotolerant and halophilic microorganisms

Saline Syst. 2005 Aug 4;1:5. doi: 10.1186/1746-1448-1-5.


Microorganisms that adapt to moderate and high salt environments use a variety of solutes, organic and inorganic, to counter external osmotic pressure. The organic solutes can be zwitterionic, noncharged, or anionic (along with an inorganic cation such as K(+)). The range of solutes, their diverse biosynthetic pathways, and physical properties of the solutes that effect molecular stability are reviewed.
