Abstract
A suspension of a microorganism or a plurality of different microorganisms is added to a dispersion of .beta.-chitin gel, and the resultant dispersion is molded and dried to produce an immobilized microorganism such as a film or membrane containing the microorganism. The .beta.-chitin gel dispersion is prepared by isolating and grinding .beta.-chitin from a source such as cuttlefish pen or squid pen, dispersing the ground .beta.-chitin in water and forming a gel dispersion. In forming the gel dispersion, the dispersion of ground .beta.-chitin is gelled and the gel is dispersed in water. Freeze-thawing may be used in gelling the dispersion of ground .beta.-chitin. A film of the immobilized microorganism can be formed on an electrode to prepare a microorganism electrode.
