ABSTRACT:
A microorganism or enzyme is mixed with an alginate and a silica sol in the presence of water to obtain a liquid mixture having a pH of 3 to 10 and containing an alginate concentration of 0.5 to 3.5% (w/v) and a silica concentration originating from the silica sol of 0.5 to 35% (w/v). The mixture is contacted with a gelling agent in the form of an aqueous solution to obtain a gel containing the microorganism or enzyme.
