FREMGANGSMAADE TIL DESINFICERING OG VASK AF IMMOBILISERET LACTASE

摘要

Effective disinfection and washing of immobilized lactase from Aspergillus oryzae is carried out after a period of hydrolyzing lactose by treatment of the immobilized lactase with aqueous solutions of pH's 2 to 4 and 6 to 8.7, one or both of which contain a disinfectant. The solution having a pH of 6 to 8.7 may be a phosphate buffered solution. The lactase may be immobilized on a high polymer compound by covalent linkage. The immobilized lactase has outstanding resistance to chemicals and wide pH stability so that decrease of lactase activity is minimized.
