[Properties of immobilized acid proteinase from Aspergillus awamori]

pH-optimum, thermal stability and storage stability of immobilized acid proteinase from Aspergillus awamori obtained by covalent binding on silochrome through glutaraldehyde were studied. Acid proteinase immobilization was found to shift towards the acid range by a unit. Thermal stability of the immobilized preparation was lower than that of the native enzyme.
