Flavonoid esters synthesis using novel biocatalytic systems - CAL B immobilized onto LifeTech (TM) ECR supports
In order to enhance productivity and cost-effectiveness of current lipase-catalyzed processes of flavonoid esters synthesis, different LifeTech (TM) ECR carriers varying in functional groups, polarity and porosity were hereby screened as immobilization supports for free lipase B from Candida antarct...

In order to enhance productivity and cost-effectiveness of current lipase-catalyzed processes of flavonoid esters synthesis, different LifeTech (TM) ECR carriers varying in functional groups, polarity and porosity were hereby screened as immobilization supports for free lipase B from Candida antarctica.

Highly active preparations were obtained by using hydrophobic C18 (ECR 8806M), epoxy/butyl (ECR 8285F) and primary amino (ECR 8409F) functionalized resins. Interestingly, lipase immobilized via hydrophobic interactions and covalent bonds exhibited high catalytic activity in esterification reactions using oleic acid as well as natural oils as acyl donors, yielding more than 70 % and 50 % conversion degree, respectively.
