Oil degrading organisms were enriched in MSM medium supplemented with used engine oil. Organisms showed zone of clearance of 7-24 mm on TBA and 3-16 mm on used engine oil supplemented MSM plate. The % degradation of used engine oil was 14 to 37%. Isolate DP-1 showed highest activity, it was identified as Pseudomonas aeruginosa DP-1 by 16S r-RNA gene sequencing analysis. The organism gave 2, 6-dichlorophenol indophenol test positive. After optimization the used engine degradation was as high as 68% in 32 days of incubation. Selection and optimization resulted in 1.8 fold increase in used engine oil degradation potential of the organism.
