				 Background: Oily wastewater which is released from different industries is one of the most common pollutants. Efficiency of conventional methods such as gravity separation and skimming, dissolved air flotation, demulsifying, coagulation and flocculation are frequently not efficient enough is not acceptable. Therefore, in this study it was intended to use a new strategy that is combined by two methods. Methods: Nine crude oil degrading bacteria were isolated from oil contaminated sites in the Persian Gulf at Terminal of Bandar Abbas. Choosing cases were cultured in the ONR7a medium supplemented with 1% (v/v) of crude-oil. Two strains that had more growth and higher oil removal were chosen and identified from nine isolated strains for further study. Due to its low price and simple usage of coagulation-flocculation process, the next step of this study was ded.. View More»
