The object of this work was to study the composition of proteases synthesized by an active culture of Aspergillus kanagawaensis (I) as well as that in the presence of a cultural broth of Asp. wentii (II) which did not produce exoproteases. Enzyme complexes I and II are similar in qualitative composition but complex II has a higher proteolytic activity. The preparation containing the stimulating factor produced by Asp. wentii has been separated by gel filtration and ultrafiltration. Biosynthesis of exoproteases is stimulated by low molecular weight fractions of the cultural broth of Asp. wentii.
