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...

Background and Objective: PAHs are non-polar organic compounds consisting of two or more fused benzene multi-rings. Among these compounds, acenaphthene is a multi-ring hydrocarbon that occurs abundantly in nature. Use of microorganisms to clean the contaminations of soil can be cheap and effective. The most important acenaphthene-degrading bacteria are pseudomonas, micrococcus, and Bacillus. Th...
