[Properties of immobilized glucoamylase preparations].

The glucoamylase activity was compared with certain properties of glucoamylase preparations immobilized on silochrome and obtained with the use of glucoendomycopsin G15x, gluconigrin G20x and Asp, awamori 466 culture fluid as sources of native enzymes and 2,4-toluylendiisocyanate, cyanurchloride, glutaric aldehyde and gossypol as cross-linking agents. The most active immobilization of the enzyme by silanized silochrome is obtained when the Asp, awamori 466 culture fluid is used as soluble glucoamylase and gossypol--as a cross-linking agent.
