| Abstract | ||
| Strains of heterotrophic and hydrocarbon- utlizing bacteria were isolated from um- Qasir soil in Basrah .Aportion of expermential soil was treated with Regular Basrah crude oil .Another part of the soil was left untreated .One month after crude oil spreading ,adapted bacteria were isolated at different soil depths in the two plots .Bacteri genera Pseudomonas,Micrococcus ,Flavobcteriums ,Vibrio,Bacillus ,Staphylococcus ,Aeromonas ,Klebsiella ,Actinomycetes ,Acinetobacter ,Artheobacter,and Corynebacterium ,were identified.The biodegradation potential of the hydrocarbon- utlizing microorganisms isolated from polluted and unpolluted soils were similar. The high number of heterotrophic and hydrocarbon- utlizing bacteria in treated soil compaired with untreated ,There is high segnificant differences (p<0.01)in the total count of bacteria,were obtain among different depths,the highest bacterial count was isolated from the surface layer 0-20 cm in both treated and untreated soil. | ||
