A New Method of Detection of Plant Extracellular Proteolytic Enzymes
Nová metóda dôkazu rastlinných extracelulárnych proteolytických enzýmov
Pomocou nerozpustného chromogénneho substrátu (čierny gelasfér) sa vypracovala jednoduchá, citlivá a reprodukovateľná metóda dôkazu extracelulárnych proteolytických enzýmov. Extracelu - lárne proteolytické enzýmy (produkované kalusovou alebo suspenznou kultúrou) hydrolyzujú čierny gelasfér. Zafarbenie okolo kalusovej kultúry a pod ňou je znakom činnosti kalusovou kultúrou produkovaných extracelulárnych proteolytických enzýmov. Intenzita zafarbenia kultivačného mé - dia je mierou aktivity extracelulárnych proteolytických enzýmov suspenznej kultúry.
Klíčová slova:
extracelulárne proteolytické enzýmy – nerozpustný chromogénny substrát – čierny gelasfér – Chelidonium majus L.

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.
