Ecological and comparative taxonomic investigations were carried out on 49 Aeromonas strains isolated from water samples of two moderately alkaline lakes of Hungary, Lake Balaton and Lake Ferto/Neusiedlersee together with 3 authentic strains of Aeromonas hydrophila. Five phena were created at greater than 92% similarity value using the UPGMA method with the Jaccard coefficient. Strains isolated from Lake Balaton were determined as A. hydrophila, while strains originated from Lake Ferto were identified as A. hydrophila and A. sobria. The Ferto isolates of A. hydrophila grew only at higher salt concentration (5% NaCl). This might be an adaptation to the higher salt contents in the water of Lake Ferto. However, no specific differences were detected in their behaviour against alkaline pH values. The wide range of their degradative enzymes indicate that aeromonads can play an important role in nutrient cycling.
