Abstract: The disclosure is directed to the production of the enzyme glucoamylase. During the growth of glucoamylase producing microorganisms, ammonium hydroxide or ammonia gas is introduced into the growth medium to provide a source of ammonia and to maintain the pH of medium at the level where optimum growth of the microorganisms occurs.

Abstract: The invention is directed to a process for preparing dextrose containing syrups having a predictable dextrose content. During enzymatic hydrolysis of starch to dextrose, C1O2 is incorporated into the hydrolysate to inactivate the enzyme when the dextrose content of the hydrolysate reaches a predetermined level.
