Biodegradation of hydrocarbon by Enterobacter sp IAA-01 isolated from hydrocarbon exploration site soil of Kukawa Northeastern Nigeria

The accidental release of diesel and other hydrocarbon to the environment lead pollution environment. search for an environmentally friendly technique remediation such polluted is not be overemphasis. Microorganisms are used in bioremediation environments. Hydrocarbon-degrading bacterium isolated from exploration site soil Kukawa North-eastern Nigeria, was studied its biodegradation potential diesel. Culture base techniques using nutrient agar mineral salt medium supplemented with 1% used. isolate identified as Enterobacter sp. strain IAA-01.  Identification carried out 16S rRNA sequencing molecular phylogeny analysis Phylip software. Gravimetric conducted measure percentage 21 days, confirmed Gas chromatography (GC) where degraded 78% after days total degradation revealed GC days. results prevailed ability IAA-01 effectively biodegrade oil.   Key words: sp., biodegradation, gas chromatography, pollution.
