title: [Comparative characteristics of microbial proteases by the level of hydrolysis of protein substrates].
abstract: Screening of enzyme preparations displaying a maximum proteolytic activity at pH 4.0-5.5 and effecting deep proteolysis of plant proteins was performed. Amyloprotooryzin prepared from Aspergillus oryzae 387 containing a complex of proteolytic enzymes was the most effective. The amino acid composition of the hydrolysates obtained was studied. Amyloprotooryzin increased the contents of amino acids by 108-227%, depending on the substrate used. The enzymatic complex of amyloprotooryzin was studied; in addition, proteases, alpha-amylase, exo-beta-glucanase, and xylanase were detected in the complex.
