  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 activit
