Species of Pseudomonas and Bacillus Isolated from Refined Oil-contaminated Soil Showed the Potential to Efficiently Degrade Diesel

The high rise in the exploration and usage of petroleum products have led to widespread contamination environment. Thence, continuous search for microorganisms with potential mineralize these pollutants is necessary. This study was conducted isolate, identify determine diesel degradation bacteria from oil-contaminated soil collected three filling stations Azare, Katagum LGA, Bauchi State, Nigeria. degrading were identified using standard protocols. isolates screened spectrophotometrically their utilize 1% (v/v) as sole carbon energy source best candidate used determining effect concentration on its biodegradation. results revealed presence bacterial species including Pseudomonas aeruginosa, putida Bacillus subtilis. P. Putida showed highest at 120 h an absorbance 2.27±0.03 600 nm followed by aeruginosa (2.23±0.03) observed 2% least recorded 3% 2.40±0.00, 2.20±0.00 respectively. detection degraders crucial light lingering efficient hydrocarbon bioremediation since degrative capability could be enhanced deployment diesel-contaminated environments.
