Cell suspension culture of the opium poppy plant (Papaver somniferum L.) was permeabilized by Tween 80 and immobilized by glutaraldehyde. The pH optimum of the immobilized cells’ invertase is 4.6 and the temperature optimum is 50 °C. The enzyme hydrolysis was linear for 5 h, reaching 69 % of conversion. The immobilized cells are characterized by a high invertase activity and showed convenient mechanical properties.
