Isolation and identification of fresh water light crude oil degrading bacteria was the aim of this
in vitro study. Moreover, determining the optimum conditions for oil degrading activity. Total
bacterial count and bacterial indicators were counted in parallel with oil degrading bacteria in
sediment and water samples. Temperature, pH, COD and oil concentration were determined as the
optimum factors for the activity of the oil degraders. The ability of oil degrading was tested via
quantifying oil residues using gas chromatographs. The analysis of sediment samples showed the
presence of some polycyclic aromatic hydrocarbons. After four frequent screenings, oil degrading
bacteria were identified out of 225 isolates. Isolates has given the most potent crude oil degrading
activity were identified as Pseudomonas aeruginosa, Coronobacter sakazakii, klebsiella oxytoca
and Bordetella bronchispetica consequently. Oil degraders were mesothermic bacteria with
optimum pH activity from 7 to 7.5. Results can be concluded that, the consortium of the four
bacterial strains showed high efficiency of oil degradation.
