Lipases are glycerol ester hydrolases that catalyze the hydrolysis of triglycerides to free fatty acids and glycerol. Oil spilled soil samples collected from Dharmapuri and Salem districts were screened for a novel lipase producing bacteria by screening in Tributyrin agar plate and Rhodamine olive oil agar and lipase screening liquid medium. Among the two hundred isolates thirty two isolates exhibited high lipolytic activity on TBA plate assay and twenty isolate exhibited high lipolytic activity on ROA plate assay The isolate BLP 141 produces lipase more than 12 U/ml in the further lipase screening liquid medium was selected as a novel lipase producing bacteria and identified by morphological and biochemical characteristics as Pseudomonas. The 16S rRNA gene amplified by bacterial universal primer 27F and 1492R yielded 1478 bp was analysed by BLAST confirmed it as Pseudomonas gessardii and was submitted in GenBank with accession number KJ547711.
