Kinetic resolution of rac-1,2-diols using the biocatalyst Burkholderia cepacia lipase (BCL) immobilized on a biodegradable binary blend support of hydroxypropyl methyl cellulose(HPMC)/polyvinyl alcohol (PVA) has been investigated. The immobilization technique improved enzyme activity significantly and it has excellent recyclability with
The application of biocatalysis to the synthesis of chiral molecules is one of the greenest technologies for the replacement of chemical routes due to its environmentally benign reaction conditions and unparalleled chemo-, regio- and stereoselectivities. We have been interested in

DNA shuffling and saturation mutagenesis of positions F108, L190, I219, D235, and C248 were used to generate variants of the epoxide hydrolase of Agrobacterium radiobacter AD1 (EchA) with enhanced enantioselectivity and activity for styrene oxide and enhanced activity for 1,2-epoxyhexane

A microorganism with the ability to catalyze the resolution of racemic phenyloxirane was isolated and identified as Aspergillus niger SQ-6. Chiral capillary electrophoresis was successfully applied to separate both phenyloxirane and phenylethanediol. The epoxide hydrolase (EH) involved in this resolution
In this study, a highly efficient process for Candida parapsilosis-catalyzed deracemization of racemic 1-phenyl-1,2-ethanediol (PED) was described, based on a resin-based in situ substrate feeding and product removal (ISSFPR) methodology. The resin H103 was selected and used to keep the
