Abstract
The effect of nitrogen sources in the fermentation medium and the cultivation conditions on the production of proteinases with plasmin-like and prekallikrein activation activity by micromycete Aspergillus terreus 2 was investigated. The highest secretion of proteinases was achieved when the micromycete was cultivated on a medium containing both amine- and mineral nitrogen sources at an initial pH of 5.5 and at 28°С. It was established that the extracellular micromycete proteinases are equally capable of hydrolyzing fibrin and fibrinogen.
