Preparation of core-shell polymer supports to immobilize lipase B from Candida antarctica: Effect of the support nature on catalytic properties
Core–shell supports have been prepared and utilized to immobilize lipase B from Candida antarctica. The hydrophobic nature of the supports permitted to immobilize the enzyme via interfacial activation at low ionic strength. Different supports were prepared having different hydrophobicity and crossli...

Core–shell supports have been prepared and utilized to immobilize lipase B from Candida antarctica.
