title: The enzymatic activity from the sediment of the Gilau dam reservoir - Cluj county.
abstract: The enzymological studies on the sediment of the accumulation lake that has the main purpose of supplying drinking water to the city of Cluj-Napoca and the nearby villages, were aimed at the comprehensive understanding of the complex processes that happen in these habitats of special significance. In the sediment samples the following enzymatic activities have been quantitatively determined: phosphatase, actual and potential dehydrogenase, catalase, urease and protease. Non-enzymatic catalytic activity was also measured. Based on the relative values for the enzymatic activities, the enzymatic indicator of the sediment quality (EISQ) was calculated (ranging from 0.1 to 0.7). The enzymatic activities have been qualitatively determined for maltase, saccharase, lactase, cellobiase, amylase, dextranase, levanase, cellulase and inulinase. The correlation between the enzymatic and bacteriologic potential was statistically calculated.
