Purification and chemical characterization of biosurfactant. A) TLC results of carbohydrate and lipid fractions of biosurfactant. B) MS spectra of lipid moiety of glycolipid biosurfactant showing non-polar hydrocarbon chain (hexacosanoic acid, propyl ester). C) MS spectra of sugar moiety of glycolipid biosurfactant showing methyl-4- O-methyl-beta-D-xylopyranoside.
