1 CMC value was measured with purified biosurfactant.
2 Emulsification activity was measured against hydrocarbons with crude
biosurfactant at a concentration of 0.1 g/l.
3 Stabilities were determined by measuring the surface tension of biosurfactant solution.
4 Salt resistance were determined by measuring emulsification activity.
