Distribution of members of the family Enterobacteriaceae in the Istanbul Strait
Abstract The aim of this study was to determine the distribution of the Enterobacteriaceae members present in the sea water samples obtained from the stations selected at the Marmara Sea entry and the Black Sea exit of the Istanbul Strait and the effect of the physical parameters on the distribution of these indicator bacteria. A total of 126 unit isolates of the members of the Enterobacteriaceae were identified using API 20E (Biomereux) in the sea water samples obtained from the surface waters (0-30 cm) and various depths by monthly samplings from February 2006 to March 2007. Faecal and total coliform analyses were performed in order to state the bacterial pollution load using membrane filtration technique. Temperature, salinity, conductivity, pH and dissolved oxygen were measured by a CTD (SBE-15). The results of this study demonstrated that the highest bacterial abundance and pollution were present at the Marmara Sea entry of the Istanbul Strait, the number of bacteria determined below the depth of 20 m were higher than the deep discharge standards, and the deep discharge at the Marmara Sea entry of the Istanbul Strait was not attaining its purpose due to the lower layer waters were returning to the Marmara Sea instead of merging in the Black Sea, as pointed out by the bacterial levels.
