ABSTRACT:
A novel mixture of starch-degrading enzymes is produced by a strain of Cladosporium resinae (Strain ATCC No. 20495). One component of this mixture is a novel exo-.alpha.-glucanase (exo-pullulanase). The enzyme mixture is prepared by culturing the microorganism and recovering the enzyme mixture from the medium after removal of grown cells. Exopullulanase can be isolated by fractionation of the mixture. Both the mixture and the exo-pullulanase can be used in the manufacture of dextrose from starch, and alone or in conjunction with appropriate other starch-degrading enzymes, in the production of specific starch conversion products, including fructose syrups. Both the mixture and the exo-pullulanase can also be used for increasing the fermentability of high DE starch conversion products, for example, in production of low calorie alcoholic beverages.
