Starch is converted to dextrose by treatment with an amyloglucosidase obtained from cultures of Aspergillus foetida ATCC14916 or a mutant thereof (see Division C3).ALSO:Amyloglucosidase of high purity is produced by cultivating Aspergillus foetida ATCC 14916 or an amyloglucosidase-producing mutant thereof in a nutrient medium containing carbohydrate, preferably at 23 DEG to 35 DEG C. under a pressure of 15-30 p.s.i.g. Thereafter, the enzyme may be precipitated from the culture filtrate with alcohol and used to convert starch to dextrose (see Division C2). |
