Popis: The conditions for the submerged and solid-state cultivation of the micromycete Aspergillus ochraceus VKM F-4104D, producing extracellular proteinases that activate protein C in human blood plasma, were optimized. It is shown that the protein C-activating activity of the micromycete in a solid-state culture was 1.5-3.5 times higher than in a submerged culture (as calculated per milliliter of culture medium). Among the extracellular proteins secreted by A. ochraceus VKM F-4104D during submerged and solid-state cultivation, a protein C-activating proteinase with a pI of 6.0-6.3 was identified.
