Abstract :Two-liquid phase systems consisting of two insoluble liquids can be effective in removing high concentrations of hydrocarbons from aqueous environments. In this study, the removal efficiencies of Naphthalene insert ignore into journalissuearticles values(Nap);, Acenaphthene insert ignore into journalissuearticles values(Acn);, Fluorene insert ignore into journalissuearticles values(Flu);, Fluoranthene insert ignore into journalissuearticles values(Flr);, Anthracene insert ignore into journalissuearticles values(Ant);, and Pyrene insert ignore into journalissuearticles values(Pyr); at high concentrations in the two-liquid phase system were investigated. Two-liquid phase systems were constituted using Bis insert ignore into journalissuearticles values(2-Ethylhexyl); sebacate insert ignore into journalissuearticles values(BES); and aqueous fermentation media. Nutrient Broth insert ignore into journalissuearticles values(NB); and Bushnell Haas Yeast insert ignore into journalissuearticles values(BHY); medium were used as aqueous fermentation media. Acn, Flu, Flr, Ant, Pyr, and Nap were degraded at a rate of 93.1%, 80.8%, 57.6%, 68.5%, 63.8%, and 100%, respectively with BES/NB system. In the BES/BHY system, Acn, Flu, Flr, Ant, Pyr, and Nap, were degraded at a rate of 29.6%, 44.3%, 22.8%, 68.1%, and 19.7%, 45.4%, respectively. When both systems are compared, it has been shown that the BES/NB system can be effective under specified conditions.
