The paper presents studies on level hydrolytic activity of extracellular enzymes in the surface microlayer and subsurface water in the coastal lake Dołgie Wielkie. The ranking order of the potential enzyme activity rates in the studied water layers was as follows: aminopeptidase > lipase > α-glucosidase > β-glucosidase. The level of activity of all studied hydrolases was higher in the surface microlayer than subsurface water. Activity of extracellular enzymes was influenced by the season.

PL

W błonie powierzchniowej i w wodzie podpowierzchniowej przybrzeżnego jeziora Dołgie Wielkie badano aktywność enzymatyczną czterech enzymów hydrolitycznych z wykorzystaniem metody spektrofluorometrycznej. Uzyskane wyniki badań wykazały, że najwyższym poziomem aktywności enzymatycznej charakteryzowały się aminopeptydaza i lipaza. Poziom aktywności wszystkich badanych enzymów hydrolitycznych był wyższy w błonie powierzchniowej niż w wodzie podpowierzchniowej. W jeziorze Dołgie Wielkie stwierdzono dynamikę zmian sezonowych poziomu aktywności badanych ektoenzymów.
