Evaluation of petroleum-degrading potential of bacteria from water and sediment.

Characterization of Bacteria Degrading Petroleum Derivatives Isolated from Contaminated Soil and Water

جدا سازی باکتری های تجزیه کننده هیدروکربن های آروماتیک چند حلقه ای (PAH)  از دریاچه مهارلو و بررسی اثر غلظت نمک در تجزیه آن ها 

Background and Aim: In this research we isolated the bacterial species degrading polycyclic aromatic hydrocarbons (PAHs) and determined optimal salt concentration for PAH degradation.Materials and Methods: We used naphthalene and anthracene as the only sources of carbon for isolating PAH-degrading bacteria the main culture medium was ONR7a. The bacteria isolated by this method were used for the...

Isolation and identification of phenol degrading bacteria from Kor river and their growth kinetics assay

Background : Phenol and it’s derivatives were removed by physicochemical methods in the past but nowadays biological treatment has priority. Bacteria with the rapid proliferation in the presence of phenol and it’s derivatives can remove them in a good manner. The aim of this project is isolation and identification of bacteria that degrade phenol from water and sediment of Kor river and also inv...

Bioaccumulation and translocation factors of petroleum hydrocarbons in Aeluropus littoralis

Background: Polycyclic aromatic hydrocarbons (PAHs), which consist of fused conjugated aromatic rings, not only are toxic to humans and other living organisms, but will also pollute groundwater. These compounds can be point source or non-point source and are one of the most widespread organic pollutants. Some of them are suspected carcinogens and are linked to other health problems. This study ...

Characterization and Potentials of Indigenous Oil-Degrading Bacteria Inhabiting the Rhizosphere of Wild Oat (Avena Fatua L.) in South West of Iran.

Background: The contamination of ecosystem with petroleum and its derivatives is con‌sidered as one of the most crucial environmental threat in Iran. Application of micro‌organisms has been demonstrated as an appropriate and more practical alternative to clean-up petroleum hydrocarbons in the contaminated environments. Objectives: The objectives of this study were isolating r...
