This article introduces an easy to handle immobilization apparatus for the entrapment of microbial cells, organelles and enzymes in spherical gel beads. Ca-alginate beads with entrapped cells of Aspergillus niger showed typical shrinking behaviour (from 3.00 mm to 2.25 mm particle diameter). A loss of stability down to 20% of the initial strength during… CONTINUE READING
