 Abstract:


   The present work highlights the presence of extracellular hydrolytic enzymes such as amylase, caseinase, cellulase, esterase, gelatinase for some strains belonging to the genera Aeromonas, Bacillus, Brachybacterium, Enterobacter, Exiguobacterium, Lysinibacillus, Microbacterium, Pseudomonas and Yersinia isolated from water samples taken from the putative polluted sector of the Pasarea river, in the area of Tunari, Ilfov county. The 20 investigated strains belong to five families as follow: Bacillaceae, Dermabacteraceae, Enterobacteraceae, Microbacteriaceae, Aeromonadaceae, Yersiniaceae and Pseudomonadaceae. The predominant enzymatic activities were the hydrolysis of starch, casein and Tween 80. Strains belonging to the genera Aeromonas, Bacillus and Pseudomonas distinguished themselves by the presence of the five types of enzymatic activities investigated, some of them being combined.
