Abstract: The immobilization of lipase with diatomite powder as the carrier by t he means of absorption method was studied. The results of the optimal condition s for im mobilization are that pH is 7.7; temperature is in the range of 30 ℃ and 35 ℃; ionic strength is in the range of 0.01 mol/L and 0.03 mol/L; the optimal ra ti o of diatomite to lipase is 8∶1(mass ratio).

Key words: immobilization, lipase, diatomite
