title: [Stability of alpha-amylase with immobilization through its different functional groups].
abstract: The paper deals with stability of Aspergillus aryzae alpha-amylase immobilized on CM- and AE-celluloses using N,N'-dicyclohexylcarbodiimide by means of binding through its amine or carboxylic groups. The binding of the enzyme with CM-cellulose makes its preparations more stable to the effect of EDTA and elevated temperature (50 degrees C) than under fixation on AE-cellulose.
