Abstract

A PROCESS AND METHOD OF SOLUBILIZING ENZYMES IN SUCH MANNER AS TO RETAIN THEIR BIOLOGICAL ACTIVITY OVER A LONG PERIOD OF TIME OF SHELF LIFE AND A BIOLOGICALLY ACTIVE SOLUTION OF ENZYMES WHICH RETAINS SAID BIOLOGICAL ACTIVITY OVER A LONG PERIOD OF TIME AND SHELF LIFE. A METHOD OA SOLUBILIZING ENZYMES WHEREBY TO RETAIN THEIR BIOLOGICA ACTIVITY OVER LONG PERIODS OF TIME WHICH UTILIZED (1) AMYLOPSIN AND CARBONIC ANHYDRASE, (2) A CARBOHYDRATE SUITABLE AS A SUBSTRATE FOR THE AMYLOPSIN AND (3) CETYL PYRIDINIUM CHLORIDE OR NH4CU. THE SOLUTION FOR MAINTAINING AMYLOPSIN IN BIOLOGICALLY ACTIVE CONDITION (WITH OR WITHOUT OTHER ENZYMES ADDED THERETO ALSO RETAINED IN BIOLOGICAL ACTIVITY OVER LONG PERIODS OF TIME) CONTAINING, IN ADDITION TO THE AMYLOPSIN AND OTHER OPTIONAL ENZYMES, CARBONIC ANHYDRASE, NH4C1 OR CETYL PYRIDINIUM CHLORIDE AND CARBOHYDRATE SUITABLE AS A SUBSTRATE FOR THE AMYLOPSIN (NH7BR AS AN OPTION.
