Overview

By means of an insoluble chromogenic substrate (black gelasphere), a simple, sensitive and repro- ducible method of detection of extracellular proteolytic enzymes was worked out. Extracellular proteolytic enzymes (produced by a callus or suspension culture) hydrolyse black gelasphere. Colouring around the callus culture and under it is a sign of the activity of extracellular proteolytic enzymes produced by the callus culture. The intensity of colouring of the cultivating medium is a measure of the activity of extracellular proteolytic enzymes of the suspension culture.

Key words:
extracellular proteolytic enzymes – insoluble chromogenic substrate – black gelasphere – Chelidonium majus L.
