摘要：
A method of producing a milk clotting enzyme including the steps of (a) fermenting a strain of Rhizomucor miehei or Aspergillus oryzae to form a fermentation product having a glycoslated Rhizomucor miehei aspartic protease and other proteins, and (b) subjecting a quantity of the fermentation product to a deglycosylating treatment to form a coagulant preparation having an at least partly deglycoslated aspartic protease and the other proteins. The at least partly deglycosylated protease has a milk clotting activity that is at least 10% higher than a milk clotting activity of the glycosylated aspartic protease.
