چکیده انگلیسی
Biosurfactants are the superb alternates for chemical surfactants due to non-toxicity, biodegradability and cost-effectiveness. The present study describes the biosurfactant production from two isolates Bacillus amyloliquefaciens SAS-1 and Bacillus subtilis BR-15. The produced biosurfactants were characterized by fourier transform infrared spectroscopy and mass spectrometry as lipopeptides, surfactins of molecular weight 1007, 1021, 1035 and 1049â¯Da. These molecules displayed an excellent emulsification (E24 60-78%) with hydrocarbons and stability at wide temperature (4-100â¯Â°C) and pH (4-10). The biosurfactants produced by SAS-1 and BR-15 accounted for 56.91â¯Â±â¯1.52 and 66.31â¯Â±â¯2.32% enhanced oil recovery respectively in sand pack column experiment on account of their high surface activity. Further, the biosurfactants efficiently augmented (75-94%) the engine oil degradation with microbial consortium, more than threefold as compared to that without biosurfactants (22-31%). Hence, the presented strains have high potential for environmental applications like enhancing oil recovery and bioremediation of oil spills.
