초록

A tentative composition and some properties of biosurfactants, type I and type II, from Pseudomonas sp. SW1 are described. Biosurfactant type I and II are soluble in water, dichloromethane, chloroform, and a mixture of chloroform and methanol, respectively. The UV absorption spectrum of biosurfactants showed three characteristic peaks in the range of 212, 250 and 365nm, respectively. As a result of IR spectroscopy, GC/MS analysis and biochemical analysis, biosurfactant type I was a polymeric biosurfactant containing carbohydrate, lipid and protein. The carbohydrate was characterized as rhamnose. The lipid part consists of $C_{14}-C_{23}$ fatty acid when analyzed by GC/MS. The biosurfactant type II was a rhamnolipid consisting of carbohydrate and lipid.
