Characterization and properties of the biosurfactant produced by Candida lipolytica UCP 0988 Electron. J. Biotechnol.
Diniz Rufino,Raquel; Moura de Luna,Juliana; de Campos Takaki,Galba Maria; Asfora Sarubbo,Leonie.
Background: Biotechnological processes are costly, especially for the production of biosurfactants. The successful production of a biosurfactant is dependent on the development of processes using low cost raw materials. Considering the importance of the characteristics of a biosurfactant to facilitate its industrial application, the properties of the biosurfactant produced by Candida lipolytica through previously optimized medium have been established. Results: The yeast was grown for 72 h to determine the kinetics of growth and production. The surface tension of the cell-free broth was reduced from 55 to 25 mN/m. The yield of biosurfactant was 8.0 g/l with a CMC of 0.03%. The biosurfactant was characterized as an anionic lipopeptide composed of 50%...
