ABSTRACT:
A method of preparing an enzyme immobilizing carrier includes the steps of providing a material consisting of kaolin mineral. The material is subject to acid treatment with a strong acid having a pH of 4 or less, and hydrothermal treatment at a temperature of from about 100.degree. C. to about 250.degree. C. The material is dried, thereby producing a porous powder. The porous powder is baked at a temperature of from about 350.degree. C. to about 1000.degree. C., for thereby producing the carrier.
