PREPARATION METHOD OF, IMMOBILIZED ENZYME OR IMMOBILIZED MICROBE ABSTRACT OF DISCLOSURE:, A method of preparing an immobilized enzyme or an immobilized microbe is disclosed characterized in that after an enzyme or a microbe is added to an aqueous solution of sodium alginate with an M/G ratio of 0.01 - 0.8 the solu-, tion is brought into contact with an aqueous solution containing barium ion or strontium ion for gelation. Enzymes or microbes immobilized by this method have the advantage that the strength of the immobilizing gel is improved, while the inherent activity and characteristics of the enzymes or microbes are not inhibited.
