[Coordination immobilization of fungal proteinases]

The possibility of coordination immobilization of fungal enzymes from Aspergillus niger MB and Aspergillus flavipes on the styrene copolymer with maleic acid has been explored. Optimal conditions for preparing insoluble chromium-containing enzyme polymeric complexes have been studied. The synergistic effect of salts of different metals on stability of chromium-containing immobilized preparations has been demonstrated. Properties of the resultant immobilized preparations have been examined.
