    • An immobilized lipase is prepared for transesterification of oils, fats or phospholipids in a reaction system containing a very small amount of water such as 50 to 2,000 ppm. The lipase may be a phospholipase such as phospholipase A.sub.2. In a first embodiment, lipase from a microorganism of the genus Rhizopus, Mucor, Alcaligenes or Candida is immobilized on the surface of a hydrophobic, insoluble organic polymer carrier having pores of an average diameter of 10 nm or larger. A solution of lipase is contacted with the polymer carrier for 10 minutes to 40 hours to covalently bond the lipase to the carrier. The immobilized lipase is dried under reduced pressure to a water content of 0.5 to 30 wt %. In a second embodiment, lipase is immobilized on the surface of a polymer carrier such as a hydrophobic, insoluble organic polymer carrier having a pore diameter of 5 to 1,000 nm and having a functional group capable of binding lipase in a aqueous solution and an anion-exchange group on the surface. Preferably, the functional group is an epoxy group and the anion-exchange group is a tertiary amino group. The lipase may be obtained from the same microorganism as in the first embodiment or from another lipase-producing microorganism. Immobilization can be carried out as in the first embodiment. It is preferred to contact a solution of lipase with the polymer carrier in the presence of a fatty acid or derivative thereof for 10 minutes to 10 hours to covalently bond the lipase to the polymer carrier.
    • 制备固定化的脂肪酶用于在含有非常少量的水如50-2000ppm的反应体系中对油,脂肪或磷脂进行酯交换反应。 脂肪酶可以是磷脂酶如磷脂酶A2。 在第一实施方案中,将来自根霉属,毛毛虫,产碱杆菌或假丝酵母属的微生物的脂肪酶固定在具有平均直径为10nm以上的孔的疏水性不溶性有机聚合物载体的表面。 将脂肪酶溶液与聚合物载体接触10分钟至40小时,以将脂肪酶共价键合到载体上。 将固定化的脂肪酶在减压下干燥至含水量为0.5〜30重量%。 在第二实施方案中,将脂肪酶固定在聚合物载体的表面上,例如孔径为5至1000nm的疏水性不溶性有机聚合物载体,并且具有能够在水溶液中结合脂肪酶的官能团和阴离子交换树脂, 交流组在表面上。 优选地,官能团是环氧基团,阴离子交换基团是叔氨基。 脂肪酶可以从与第一实施方案相同的微生物获得,或从另一种脂肪酶生产微生物获得。 固定可以如第一实施例那样进行。 优选在脂肪酸或其衍生物的存在下将脂肪酶与聚合物载体接触10分钟至10小时以将脂肪酶共价结合到聚合物载体上。
