Changes in the bacterial community composition of different habitats along a polluted river (Suquía River, Cordoba, Argentina)
Resumen:
he objective of the present study was to investigate the influence of environmental conditions on the bacterial community composition in water, sediment and riparian soilduring different water flow periods. For this purpose, samples of three habitats (water, sediment and riparian soil) were collected from five polluted sites and one reference site along the Suquía River during high and low water flow periods. The pH, dissolved oxygen, conductivity and water temperature were measured ?in situ?, with total organic carbon content, nitrate and ammonia concentration being evaluated for all samples. In addition, pH, conductivity and total N were determined in the sediment and riparian soil samples, and the bacterial community composition of water, sediments and riparian soil samples was monitored using restriction fragment length polymorphism of the 16S rRNA gene. The results showed that the bacterial community composition of water was different from that of sediments or riparian soil. A re
