An enzyme or microorganism is entrapped within the gel matrix of a sulfated polysaccharide (said polysaccharide containing more than 10 w/w% of a sulfate moiety in its molecule) in the presence of ammonium ion, a metal ion, a water-soluble amine or a water-miscible organic solvent. The immobilized enzyme or microorganism thus obtained shows a high level of catalytic activity for a long period of time and can be used for continuous enzymatic reactions with substrates. |
