Abstract
A process for immobilizing enzyme-containing microbial cells by contacting such cells with an aqueous agar solution containing from about 1.0 to 8.0% sulfate moiety on a weight/weight basis, contacting a solution of inorganic sodium salts with a stream of the cell mixture whereby agar fibers containing cells are formed; and recovering the cell-containing agar fibers produced.
Claims14
A process for immobilizing enzyme-containing microbial cells comprising:
- (a) contacting enzyme-containing microbial cells with an aqueous agar solution at a temperature of from about 40.degree. to 60.degree. C.;
- said agar containing from about 1.0 to 8.0% sulfate moiety on a weight/weight basis;
- (b) contacting a 0.10 to 5.0 molar solution of inorganic sodium salts at a temperature of from about 0.degree. to 20.degree. C. with a stream of the mixture formed in a) above whereby agar fibers containing cells are formed;
- and
- (c) recovering said cell-containing agar fibers.
