Ionic liquids, composed of organic cations and either organic or inorganic anions remain liquid over a wide range of temperature. ionic liquids are a new group of solvents or extractants of great interest as a potential 'green solvent'. Ionic liquids are gaining wide recognition as novel solvents in many research fields, such as chemistry, chemical engineering, electrochemitry, etc. However, not much researches have been done related to biotechnology using ionic liquids, while a lot of researches have been performed in chemistry. The merits of ionic liquids in bioseparation technology are originated from some unique properties of ionic liquids, such as negligible vapor pressure, good thermal stability, controllable viscosity and miscibility with water and organic solvents. An appropriate selection of ionic liquid for bioprocesses requires basic knowledge on physicochemical properties of ionic liquids. This review gives a brief overview on the application of ionic liquids in biotechnology, including bioconversion and bioseparation.
