| Abstract: | Summary Synthesis of a bioemulsifier using a lipase from Pseudomonas sp. with fructose and vinyl laurate was carried out in anhydrous pyridine. The synthetic product was identified as laurylfructose with an emulsifying activity on various hydrocarbons, edible oils and petroleum oils. The compound reduced the surface tension of distilled water from 72 mN/m to 29 mN/m and the interfacial tension of water/n-hexadecane from 50 mN/m to 6 mN/m. |
