Biosurfactant
Hydrophilic Moiety Hydrophobic Moiety
Biosurfactant
Biosurfactants are surface-active biomolecules produced by microorganisms.
• Acid• Peptide cations or anions• Mono-, di- or polysaccharides
Hydrophilic Moiety
• Unsaturated or saturated hydrocarbon chains • Fatty acids

Oil displacement activities of foamate and powder were comparable to a commercial dispersant (Slickgone NS) and much higher than a synthetic surfactant (Tween 20).

Lipopeptide biosurfactant could be produced from chitosan-immobilized
Bacillus sp. GY19 in stirred tank fermenter.1
Lipopeptides could be recovered from cell-free culture medium by foam
fractionation process.
Lipopeptides have good surface activity, low toxicity, and stable under
various conditions.
Both foamate and powder containing lipopeptides could be used directly
