title: [Glucoamylase immobilization on silochrome using gossypol].
abstract: The paper is concerned with conditions of glucoamylase binding with silanized silochrome using gossypol, dialdehyde isolated from cotton-plant. Kinetic properties of the immobilized enzyme are studied. The enzyme pH optimum does not change with immobilization and the temperature optimum is shifted from 50 degrees to 60 degrees C; a certain increase of the seeming Km is also observed. A high yield of the enzyme activity in immobilization evidences for the possibility of using gossypol as a binding agent in glucoamylase immobilization.
