Cellulase activity of Trichoderma reesei immobilized on gauze covered with hydrophilic and hydrophobic copolymers

The effect of the surface properties of the matrix for immobilized Trichoderma reesei on cellulase activities was studied. The immobilization was based on an adhesion method. The carriers were obtained by coating cellulosic gauze with hydrophilic and hydrophobic monomers using a radiation copolymerization technique. The cellulase activities of the organisms immobilized on the matrices coated with the copolymers were higher than those of the free organisms. Hydrophilic matrices allowed increased growth of the immobilized organisms with increased cellulase activity.
