Abstract
Enzymes or enzyme producing microorganisms are immobilized by contacting an aqueous medium containing an enzyme or enzyme producing microorganism with tannin, a long chain, polyamine, cationic flocculating agent and a crosslinking agent and separating the resultant enzymatically active reaction product from the aqueous medium. The reaction product has improved physical strength for use in a column bed reactor. A preferred flocculating agent is a water soluble epihalohydrin/polyamine copolymer.
