Research on the qualitative enzymatic activities in sediments from Secu and Gozna-Văliug dam reservoirs, Caraş-Severin county (Romania)
Journal Title: Extreme Life, Biospeology & Astrobiology - International Journal of the Bioflux Society - Year 2011, Vol 3, Issue 2
Abstract
Six sediment samples (three from Secu Lake and three from Gozna-Văliug Lake) were collected and analyzed qualitatively, enzymologically. In the sediment samples, the following enzymatic activities have been qualitatively determined: four oligase activities (maltase, saccharase, lactase and cellobiase) and five polyase activities (amylase, cellulose, dextranase, glicogenase and inulinase). The studied activities were determined in each sample and they were found to display variations in the intensities of the processes depending on the sampling place. Generally, the highest intensity of qualitative enzymatic activities was registered in case of oligases.
