PURPOSE:An immobilized microorganism, obtained by entrapping a suspension of a microorganism in a film of calcium alginate, containing the microorganism in a suspension and capable of exhibiting improved effect, e.g. very ready inflow of cultivation nutrient sources and substances and outflow of metabolites, etc. CONSTITUTION:An immobilized microorganism obtained by dripping a suspension of a microorganism containing calcium ions present therein into a sodium alginate solution to form films of calcium alginate on the surface of the driplets. The concentration of the microorganisms in the suspension need not be specially high and may be about 10<3>-10<6> microorganisms/ml. A calcium salt, e.g. calcium chloride, is added to the suspension. The concentration thereof is preferably 0.5-1.0%. The sodium alginate solution into which the calcium salt is dripped is preferably adjusted to an aqueous solution in about 0.5-5% concentration.
