To evaluate bacterial biodegradation of organic contaminants in a tidal rier, the effects of salinity on the activity of heterotrophic bacteria were examined. It was revealed from experiment that salinity content affect bacterial respiration and population. It was observed that, the greater the change in salinity the greater the effect on the bacteria. With a stable level of salinity, the surviving bacteria managed to acclimate and return to normal respiration and population levels after a period of several hours. Experiments in the actual tidal river with chambers verified the laboratory results and demonstrated that the damage caused to the bacteria by salinity variation.
