Microbiological research on the enzymologic potential of Aries river (Romania) sediments

Ten sediment samples from Arieș river were collected and these samples have been analyzed qualitatively enzymologically. In the sediment samples, the following enzymatic activities have been qualitatively determined: four oligase activities: maltase, saccharase, lactase and cellobiase and three polyase activities: amylase, dextranase and inulinase. The studied activities were determined in each samples and displayed variations in the intensities of the processes depending on the sampling place. Generally, the highest intensity of qualitative enzimatic activities were registered in case of the oligases.
