title: [Production of proteinases in the process of developing cultures of Streptomyces thermovulgaris T-54].
abstract: The secretion of some proteolytic enzymes by Streptomyces thermovulgaris T 54 was studied using artificial chromogenic substrates of proteinases. Maximum accumulation of the enzymes hydrolysing Z-Glu-pNA and Z-Ala-Ala-Leu-pNA occurred during autolysis of the culture. Two peaks of activity were observed, when DNP-Gly-Gly-Ile-Arg was used as a substrate, one of them being correspondent to prevalence of dense colonies in the culture and the other to the prevalence of friable networks of hyphae.
