Abstract
A carrier for immobilization of microorganisms is prepared by impregnating a fabric such as cotton gauze having a mesh size of 10-50 with 20-50% by weight of a vinyl monomer such as ethlene glycol methacrylate and polymerizing the monomer with ionizing radiation to form a polymer coating on the fabric. A microorganism such as Trichoderma reesei is grown in a liquid culture medium in contact with the polymer-coated fabric and the polymer-coated fabric is recovered containing growing cells of the microorganism. The polymer-coated fabric has high air permeability and permits good diffusion of liquid culture medium.
