Abstract
Porous cellulose beads are prepared by distributing droplets of a solvent mixture containing a cellulose derivative into an aqueous solution to form porous beads which are then washed and hydrolyzed to form porous cellulose beads. The porous cellulose beads, which may be cross-linked, if desired, by suitable treatment, are useful carriers to which enzymes can be immobilized.
