ABSTRACT

Contradictory opinions exist regarding the
fatty acids content of the bioemulsifier obtained from Yarrowia lipolytica yeast. Our research with Y. lipolytica EH 59 strain showed that cells cultivated on glucose, glycerol
or soybean oil excreted a bioemulsifier which does not contain fatty acids permanently
bound to polysaccharide-protein matrix. Fatty acids profiles of cell membranes
and the bioemulsifier posed similar composition, indicating that rather than
being a selective excretion, they are impurities from the cells responsible for
the detection of fatty acids in the bioemulsifier.

Key words: bioemulsifier, biosurfactant, fatty acids, Yarrowia lipolytica, yeast.
