Abstract

The complex is prepd. by dispersing the cellulose deriv. in an aqs. soln. of the enzymen, esp. a protease, and particularly rennet, in the presence of a buffer maintaining the pH of the soln. at 5-10, esp. 6-9, and effecting contact between the two at 0-45 degrees C for a time sufficient for the enzyme to become fixed onto the cellulose, i.e. 24-48 hrs. The amt. of enzyme used is 0.1-100%, esp. 1-60% by wt. of the cellulose used. The cellulose deriv. is obtd. by chlorinating or sulphochlorinating an alkali cellulose in an org. liq. which is not destroyed by the chlorinating agent, e.g. pyridine or dioxane.
