BIODEGRADATION OF AUTOMOBILE OIL EFFLUENT BY Pseudomonas aeruginosa

Manuscript History: The used engine oil and washed water of automobile workshops causes soil to lose its useful properties such as fertility, water-holding capacity, permeability and binding capacity. Biosurfactant, synthesized by microorganisms, is a structurally diverse group of surface-active molecule can be employed to degrade the automobile waste engine oil. In the present study, it was observed that Pseudomonas aeruginosa MCCB 0037 showed high potential to produce biosurfactant and showed best degradation of the automobile effluent oils in Diatomaceous earth carrier based formulation. It was observed that oil degradation was found to be 75% and 47.50% in the third week, when CBMI was supplemented with inorganic nutrient and glycerol, respectively. Also, shelf life of CBMI was determined by serial dilution method that indicated CFU count of Pseudomonas aeruginosa
