Room temperature ionic liquids offer a stable, polar medium for biocatalysis. Enzymes, especially lipases, show enhanced activity and selectivity in these unique solvents, enabling novel recycling and recovery methods.

Area of Science:

  • Biocatalysis and Green Chemistry

Background:

  • Room temperature ionic liquids (RTILs) are non-volatile, thermally stable, and highly polar solvents.
  • Their moderate hydrophilicity and unique properties make them potential alternatives to traditional reaction media.

Purpose of the Study:

  • To discuss the application of RTILs as reaction media for biocatalysis.
  • To highlight the performance of enzymes, particularly lipases, in RTILs.

Main Methods:

  • Enzymatic reactions were conducted in various ionic liquid media, including anhydrous and aqueous biphasic systems.
  • Enzyme activity, enantioselectivity, and operational stability were evaluated and compared to traditional solvents.

Main Results:

  • A wide range of enzymes demonstrated catalytic activity in ionic liquids.
