Development activities were aimed at the elaboration of the experimental workshop production technologies for glycoamylase of mould fungus origin. For the fermentation a genetically stabilized Aspergillus niger strain titled ATCC 22343/65 was selected. In the scale up experiments composition of the medium was optimalized by orthogonol schedules of central layout, and 12-14 GAU. cm-3 enzyme activity was reached in this way. A processing and formulation procedure was developed for the economical production of a glycoamylase enzyme meeting the industrial quality requirements and having adequate - 100 GAU. cm-3 - specific activity. Storage characteristics and stability of the product are equally excellent, and according to the evidence of the application technical tests it comes up also to the international level
