Since the biosurfactant shows a smaller
CMC value than those of other biosurfactants from yeasts described
in the literature, as values of 2.5% found for biosurfactants from C.
lipolytica [29] and C. glabrata [30] and of 0.6% for the biosurfactant
from C. antarctica [31], its application at 0.125% is acceptable when
compared to others surface active biomolecules.
Although the literature is sparse in describing methods of
removing oils in solid surfaces, the application of biosurfactants
in removing adsorbed hydrocarbons in soils has been reported
frequently. Souza-Sobrinho et
