  • Method of producing enantioselective immobilized candida rugosa lipase
    Patent number: 8129152
    Abstract: Immobilization of Candida rugosa lipase on a carrier selected from the group consisting of macroporous adsorbent resin of the acrylic type, synthetic epoxy activated resin and Mg—Al-hydrotalcite enhances its enantioselectivity by six to seven folds. The immobilized Candida rugosa lipase is suitable for use in resolution of racemic alcohols and/or carboxylic acids, particularly in resolution of racemic menthol or production of menthyl esters.

  • Production of wax esters
    Patent number: 7557228
    Abstract: Wax esters are prepared by reacting a solution of palm oil in an organic solvent with oleyl alcohol in the presence of an immobilized lipase wherein molar ratio of palm oil to oleyl alcohol is between 1:2 and 1:4. Immobilized lipase used is present in an amount which is equivalent to not less than 1000 ?g of protein per milli-mole of palm oil used and the reaction is carried out at 40° C. to 50° C. for a period of not less than 5 hours. The organic solvent used has a value of log P not less than 3.5.
