Biodegradation of Waste Oil By Some Bacterial Species

Abstract

The Results showed the ability of Pseudomonas fluorescens, Aeromonas SP., Micrococcus luteus and Proteus vulgaris degradation of oil residues in liquid medium in each alone or interacted. results showed high ability of Pseudomonas fluorescens to degradation of oil residues which was 93%, as well as the results showed high ability of synergistic bacteria Pseudomonas fluorescens, Aeromonas SP., to degradation oil residues in liquid medium which reached 86%.while showed synergistic bacteria Proteus vulgaris and Micrococcus luteus less ability to decomposition oil residues which reached 54%.the conducted study depend on Gas -Chromatography and infrared spectrum as good of scientific indicator.
