  • Immobilization of thermostable microbial lipase by adsorption to macroporous inorganic carrier particles
    Patent number: 5342768
    Abstract: A particulate immobilized microbial lipase is prepared by adsorption of lipase to macroporous inorganic carrier particles having specific characteristics. The carrier particles contain at least 65% silica or silicates, an excess of 90% particles having a size between 100 and 1000 .mu.m and an excess of 80% pores exhibiting a diameter of between 12 and 45 times the diameter of a lipase molecule. The lipase is adsorbed to the carrier particles by contacting the particles with an aqueous solution of lipase and drying the particles to a water content between 1 and 20%. The lipase is preferably a thermostable lipase from a Humicola species, Candida antarctica or Rhizomucor miehei. The particulate immobilized lipase is cheap to produce, exhibits a high specific activity, and can be used for interesterification of fats, hydrolysis of fats or synthesis of fatty acid esters.
