Popis:	he presence of proteins in the culture liquid of filamentous fungi under study was found to induce the secretion of proteinases. The inhibitory analysis of the major extracellular proteinases of the saprotrophic fungus Trichoderma harzianum and the phytopathogenic fungus Alternaria alternata showed that they both belong to the group of serine proteinases. The substrate specificity of these proteinases and their sensitivity to inhibitors suggest that the enzyme of T. harzianum is a subtilisin-like proteinase and the enzyme of A. alternata is a trypsin-like proteinase. This difference between the proteinases may reflect the physiological difference between their producers (saprotroph and phytopathogen).
