Immobilization of lipase by adsorption on a particulate macroporous resin

摘要: Lipase is immobilized by adsorption on a polymethacrylic acid ester resin such as polymethylmethacrylate cross-linked with divinyl benzene. The preferably particulate, macroporous having an average pore radius of 100-200 Å, total surface area 25-150 m 2 /g and particle size 100-1,000 μm. lipase may be obtained from Mucor miehei, Candida antarctica, Pseudomonas cepacia or Humicola lanuginosa. dried used for interesterifying ester, hydrolyzing synthesizing ester. Interesterification can carried out continuously in fixed-bed column.
