Biosurfactants are microbial molecules which acting on the liquid surface and interface, providing the formation of stable emulsions. Their production is closely related to the ability of microorganisms to use hydrocarbons from contaminated environments for its growth. Besides, they can be produced from renewable and low-cost substrates such as agro-industrial residues. This work was aimed for biosurfactant production by Serratia marcescens UCP/WFCC 1549 using wastes and its potential for fuels biodegradation after its acclimatization on diesel. The best results were obtained in the medium containing 6% of cassava wastewater and 7.5% of corn post frying oil, with reduction of the water surface tension from 70 to 26.2 mN/m. The emulsification index obtained in this condition was 64.0% to diesel, 57.69% to corn post frying oil and 54.17% to engine burned oil. The results obtained after acclimatization of S. marcescens on 15% of diesel shown higher values of fuels degradation to 79.63% (cotton biodiesel), 65.57% (sunflower biodiesel), 60.50% (diesel), 57.20% (gasoline) and 39.26% (kerosene) using 2,6 dichlorophenol-indophenol (DCIP) as redox indicator.
