Studies and research in the field of ammonia pollution treatment have led to the fact that microorganisms have a major role in treating such environmental pollution and thus contributing to environmental balance as they have the ability to dismantle ammonia into harmless elements. This study has been carried out on the Tobruk Bay aiming to detect the level of ammonia contamination from different sources and the potentiality of using bacteria to degrade it. The studied area involving 6 sites are namely the Corniche Beach, Commercial Port and, which has a pipe for the discharge of untreated sewage, Electricity Company and Desalination Plant, which use heavy fuels in the city’s operations, in addition to the Brega and Gulf Oil Companies. The results of ammonia contamination were 0.776mg/l, 0.180mg/l, 0.180mg/l, 0.280mg/l, 0.190mg/l, 0.240 mg/l for the Commercial Port, Electricity Company,El Brega Company, the Corniche Beach, Desalination Plant and Gulf Oil Company respectively. It was noticed that the higher level of concentration of ammonia at the Corniche Beach due to the flow of untreated sewage. On the other hand, the ammonia-dissolving bacteria were isolated from 3 sediment sampleswere collected from Corniche Beach at a distance one meter from beach linebecause it was the highest level of pollution with ammonia and measured its ability toward ammoniabiodegradation. Measurements were taken at different periods of two hours, the first period was recorded as 2.11 mg/l reading of ammonia concentration, and after 22 hours it reached 0.18 mg/l, thus proving its high ability to biodegrade ammonia. The isolated bacterial was defined at Alexandria University in Egypt by 16S rRNA method .This isolate was found to be consistent with another previous study in China, the name of the lysate bacteria was Vibrio alginolyticus.
