PURPOSE: To provide immobilized enzyme or immobilized microbial cells formed to an industrially desirable sieve-form, by the use of a photo-setting resin as a binder.
CONSTITUTION: An aqueous dispersion of an enzyme such as urease, glucoamylase, catalase, and aspartase, or cells of bacteria such as Streptomyces phaeochromagenes, Aerobacter aerogenes, and Trichoderma viridae is homogeneously mixed with a photo-setting resin such as unsaturated polyester resin and unsaturated acylic resin, and irradiated with an actinic light having a wave length of 2500W6000 to obtain a sieve having a thickness satisfying the formula, an open area ratio of 3W37% and a diameters of sieve mesh of 0.5W3.0mm.
EFFECT: When packed in a reaction column, the liquid space velocity of as high as 0.01cm can be attained. The activity of the enzyme, etc. is scarcely affected by the external diffusion resistance.
