Abstract
Immobilized enzymes covalently bound to an inorganic carrier by an amino group through a bifunctional spacer have improved properties when the carrier is formed of amorphous, approximately spherical silica particles obtained from synthetic calcium silicate. The silica particles have an average particle size of from 15 to 80 .mu.m, an apparent particle volume of from 1.3 to 3 cm.sup.3 /g, and a specific surface area of from 250 to 800 m.sup.2 /g.
