Activity of extracellular enzymes on the marine beach differing in the level of antropopressure

2016

Perliński, P. | Mudryk, Z. J.

The level of activity of extracellular enzymes was determined on two transects characterised by different anthropic pressure on a sandy beach in Ustka, the southern coast of the Baltic Sea. Generally, the level of activity of the studied enzymes was higher on the transect characterised by high anthropic pressure. The ranking order of the mean enzyme activity rates in the sand was as follows: lipase > phosphatase > aminopeptidase > β-glucosidase > α-glucosidase > chitinase. Each enzyme had its characteristic horizontal profile of activity. The levels of activity of the studied enzymes were slightly higher in the surface than subsurface sand layer. Extracellular enzymatic activities were strongly influenced by the season.
