Studies on the properties of Celluclast/Eudragit L-100 conjugate
Dourado, Fernando; Bastos, Maria de Lurdes; Mota, M.; Gama, F. M.A cellulase from Trichoderma reesei was immobilized on Eudragit L-100, a reversibly soluble polymer depending on the pH of the medium. The solubility of the modified cellulase was studied at different pH values. By changing the pH, the adsorption equilibrium of the derivatized proteins is switched towards the liquid phase, thus making recycling possible. This method allows for improved stability, without major ...
