Abstract:

This study focused on a) determining spatial and temporal counts of bacteria using the Most Probable Number method (MPN), and b) evaluating the findings in terms of quality parameters of the sediment, sediment pore water and overlying water. Accordingly, surface sediment and water samples were taken at two stations located in areas of the pond, fed by groundwater polluted by agricultural runoff, with and without macrophytes in January, April, July and October 2017. It was determined that: a) while no statistically significant difference (p>0.05) was seen in the numbers of nitrification bacteria between the stations located in areas with and without macrophytes, the numbers of denitrification bacteria varied according to location and month; b) as the nitrification and denitrification bacteria counts obtained at both stations in the sampling months were extremely low (11.0-21.50 cells 100 ml-1 and 8.50-22.50 cells 100 ml-1, respectively), the bacteria did not play a sufficiently active role in the pond’s nitrogen cycle; c) the negative sediment redox potential values (-11.50 and -30.0 mV) prevented nitrifying bacteria activity; d) the low levels of denitrification bacteria detected may have been responsible for the low mineralization of the complex organic nitrogen in the sediment; e) there were no parallels between the numbers of nitrification bacteria and ammonium values in the sediment pore water, and the low levels of nitrification bacteria played a role in the ammonium concentrations in the water. Finally, macrophyte conservation and the reduction of the intensive agriculture practiced in the surrounding area could be suggested for the pond-management strategies.
