EXTRACELLULAR ENZYME ACTIVITY IN THE SURFACE MICROLAYER AND SUBSURFACE WATER IN THE COASTAL LAKE DOŁGIE WIELKIE
Journal Title: Baltic Coastal Zone - Year 2018, Vol 22, Issue
Abstract
The paper presents studies on level hydrolytic activity of extracellular enzymes in the surface mi-crolayer 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 sur-face microlayer than subsurface water. Activity of extracellular enzymes was influenced by the season.
