摘要: Aspergillus niger was immobilized by adsorption and entrapment in polyurethane foams the efficiency of retention capacity, citric acid productivity operational stability a fluidized bed reactor were then compared. The technique superior to technique, it possible obtain bioparticles capable keeping their activity for more than 25 days.
