Adhesion of filamentous microbial cells on paper covered with ionic polymers by radiation polymerization

The adhesion of filamentous microbial cells such as Trichoderma reesei was studied by using carriers covered with polymers which were prepared by the radiation polymerization of ionic monomers. The weight of the cells adhering to the carriers increased with increasing cationic monomer content, indicating that the surface of the polymers prepared from cationic and hydrophobic monomers is suitable for the adhesion of the cells. The production of cellulase in the cells adhered to polymers from cationic monomers was higher than that in cells adhered to polymers prepared from anionic monomers. The growth of the cells adhered to the surfaces of the polymers was affected by the hydrophilicity of the polymers.
