A study was carried out to examine the capabilities of three bacterial isolates to degrade crude oil in NPK- supplemented soil to which crude oil was added at 1, 3,5 and 10 %.750 mg NPK /100g soil at a ratio of 2:1:1was added to the polluted soil and mixed thoroughly. The tested bacterial isolates revealed great potentialities for the degradation of crude oil. The highest oil degradation percent 90% and 77.9% were recorded for Isolate HAC in 1% and 3% oil polluted soil after 12 weeks of incubation, respectively. The biodegradation percentages were upgraded to 98.61% and 93.11% in 1% and 3% oil polluted and NPK supplemented soil, respectively. Gas chromatographic analysis performed that Hegligcrude oil consisted of n-alkanes with chain length of C12 to C35and all the tested isolates could totally degrade chain hydrocarbons with C12, C14, C33 and C35 fractions.
