Partial characterization of biosurfactant from Lactobacillus pentosus and compa...

Moldes, Ana; Paradelo, R.; Vecino, X.; Cruz, J. M.; Gudiña, Eduardo J.; Rodrigues, L. R.; Teixeira, J. A.; Dominguez, José Manuel; Barral, M. T.

The capability of a cell bound biosurfactant produced by Lactobacillus pentosus, to accelerate the bioremediation of a hydrocarbon-contaminated soil, was compared with a synthetic anionic surfactant (sodium dodecyl sulphate SDS-). The biosurfactant produced by the bacteria was analyzed by Fourier transform infrared spectroscopy (FTIR) that clearly indicates the presence of OH and NH groups, C=O stretching of ca...

Kinetic study of fermentative biosurfactant production by Lactobacillus strains

Rodrigues, L. R.; Moldes, Ana; Teixeira, J. A.; Oliveira, Rosário

Screening of biosurfactant-producing ability of four Lactobacillus strains was performed, being shown that for all the tested strains biosurfactant production occurred mainly in the first 4 h. The Lactobacillus strains showed zones of clearing in the blood agar with a diameter <1 cm. The minimum surface tension value of the fermentation broth achieved was 39.5 mN/m for Lactobacillus pentosus CECT-4023 that repr...


Modeling of biosurfactant production by Lactobacillus Strains

Rodrigues, L. R.; Moldes, Ana; Teixeira, J. A.; Oliveira, Rosário

Screening of biosurfactant-producing ability of three Lactobacillus strains was performed, being shown that, for all the tested strains, biosurfactant production is occurring mainly in the first 7 hours. All strains reduced 8 mN/m the surface tension of the fermentation broth at the end of fermentation and lysed blood agar with scores ranging between (++) corresponding to complete hemolysis with a diameter < 1 ...
