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.

DECOMPOSITION OF ORGANIC MACROMOLECULAR COMPOUNDS BY HETEROTROPHIC BACTERIA INHABITING SURFACE MICROLAYER, SUBSURFACE WATER AND SEDIMENT-WATER INTERFACE IN THE MARINE HARBOR CHANNEL
Potential capability of heterotrophic bacteria to hydrolytic degradation different organic macromolecules in three water layers in the marine channel were determined. In studied channel hydro-lysed proteins and lipids. T...
BEYOND SALTY REINS – MODELING BENTHIC SPECIES’ SPATIAL RESPONSE TO THEIR PHYSICAL ENVIRONMENT IN THE POMERANIAN BAY (SOUTHERN BALTIC SEA)
The brackish water environment of the Baltic Sea is dominated by a strong gradient of salinity and along with salinity the benthic diversity decreases – salinity is regarded as the master factor regulating benthic divers...
