摘　　要：The present research work highlights the biosurfactant application toward enhanced pyrene degradation by Pseudomonas sp.Lipopeptide-type biosurfactant was produced from Free Air CO_(2) Enriched(FACE)soil bacterium Bacillus sp.SS105.The different concentrations of biosurfactant at different time intervals were optimized for maximum pyrene degradation and quantified through analytical methods such as the scanning process of UV-Vis spectrophotometer and GC-MS analysis.In the absence of biosurfactant,Pseudomonas sp.could degrade only 8%of pyrene at the concentration of 5 mg per 100 ml,while the degradation rate enhanced by 95%in presence of biosurfactant(5 mg/100 ml of culture).This result demonstrated that biosurfactant produced from Bacillus sp.SS105 has potential to enhance the bioavailability and biodegradation of pyrene by Pseudomonas sp.
