Biosurfactants have been widely used in various industrial fields including medicine, food, cosmetics, detergent, pulp and paper, and oil and fat degradation. The culture broth of Aureobasidium pullulans A11211-4-57 using glucose as carbon source exhibited potent surfactant activity. The culture broth was separated by column chromatographies using ODS, silica gel, and Sephadex LH-20 resins, consecutively, to provide two biosurfactants. Based on mass and NMR measurements, their structures were determined as myo-inositol lipids and named pullusurfactans F and G. These compounds showed a high degree of activity, with 27.25 mN/m and 24.07 mN/m, respectively, at 1.0 mg l(-1), which is useful for washing and cleaning agents.
