Abstract
Aspergillus niger was immobilized by adsorption and entrapment in poly urethane foams and the efficiency of retention capacity, citric acid p roductivity and the operational stability of a fluidized bed reactor w ere then compared. The adsorption technique was superior to the entrap ment. technique, and it was possible to obtain bioparticles capable of keeping their activity for more than 25 days.
