Abstract

A process of producing a high potency glucamylase enzyme system, including the retention of alpha amylase, by cultivation under submerged aerobic conditions of a strain of Aspergillus niger NRRL3112 and 3122 in a cereal grain medium of high concentration, by controlling the pH during the cultivation within a range between 4.4 and 6, preferably between 4.5 and 5.5, and a process of saccharifying and fermenting a starch product to alcohol by adding thereto a ferment including an enzyme system produced by cultivation of such strain in a suitable growth medium. The use of such a ferment results in reduction in an amount of ferments to be required and high yield of alcohol.
