Keywords: sediment samples | dam reservoirs | oligase activities | polyase activities

Six sediment samples (three from Secu Lake and three from Gozna-Văliug Lake) werecollected and analyzed qualitatively, enzymologically. In the sediment samples, the followingenzymatic activities have been qualitatively determined: four oligase activities (maltase, saccharase,lactase and cellobiase) and five polyase activities (amylase, cellulose, dextranase, glicogenase andinulinase). The studied activities were determined in each sample and they were found to displayvariations in the intensities of the processes depending on the sampling place. Generally, the highestintensity of qualitative enzymatic activities was registered in case of oligases.
