- Lipopeptide biosurfactant produced by Mucor Circinelloides UCP/WFCC 0001 applied in the removal of crude oil and engine oil from soil Nathália Sá Alencar do Amaral Marques Thayse Alves Lima e Silva Rosileide Fontenele da Silva Andrade Jeann Fabiann Branco Júnior Kaoru Okada Galba Maria Campos Takaki Ingeniería hydrocarbon Biotensoative bioremediation surface tension Biosurfactants are molecules synthesized by a wide variety of microorganisms They are characterized by the ability to reduce surface tension and act in the dispersion, solubilization, mobilization, removal and viscosity of petroleum and its derivatives. The aim of this study was to produce biosurfactant using the filamentous fungus M. circinelloides in cultivation with previously established conditions to evaluate its properties, characterize the chemical structure and investigate the application of the biomolecule in the hydrocarbon recovery. Biosurfactant yield was 6.0 g L-1. The surface tension was reduced to 26 mN m-1 with a critical micelle concentration (CMC) of 1.5%. The biosurfactant exhibited stability to surface tension under adverse environmental conditions. M. circinelloides surfactant is similar to chemical surfactants for presenting Oil displacement area of 50 cm2 in water-in-oil dispersion, as well as reduce the oil viscosity from 843.6 to 14.7 cP. Physical-chemical analyzes showed that the biosurfactant produced is a lipopeptide. The cationic character was identified by performing the zeta potential. The biosurfactant demonstrated no toxicity and recovered 95.9% of motor oil adsorbed on a clay soil sample, presenting considerable potential for use in bioremediation processes, especially in the petroleum industry. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200014 https://www.redalyc.org/journal/3032/303260200014/ https://www.redalyc.org/journal/3032/303260200014/html/ https://www.redalyc.org/journal/3032/303260200014/303260200014.epub https://www.redalyc.org/journal/3032/303260200014/movil https://doi.org/10.4025/actascitechnol.v41i1.38986 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
