Abstract
Novel immobilized cells are prepared by immobilizing microbial cells in a gel carrier wherein an absorbent for organic solvents harmful to the cells is dispersed. A method for normally culturing these immobilized cells is utilized in a medium that contains the organic solvents or to which organic solvents are added without any previous sterilization. The present invention makes it possible to realize an ideal fermentation process without requiring a sterilizing process.
