Enzymatic synthesis of esters by chiral ionic liquids coated lipase from Candida rugosa

Ionic liquids have open up new perspectives in catalysis and biocatalyst. Biocatalysis in nonaqueous media often face problems due to stability of enzyme which then lead to low activity and poor selectivity. Chiral ionic liquid coated-enzyme (CILCE) was prepared by coating Candida rugosa lipase with...
