Comparison of two yeast biosurfactants for the removal of petroleum hydrocarbons

Original language description

The aim of this paper was to produce, isolate and characterize two types of biosurfactant produced by yeasts Yarrowia lipolytica and Candida bombicola and quantify their potential for stimulated attenuation. Critical micelle concentration (CMC) and minimum surface tension (MST) were determined for both biosurfactants. CMC = 31 mg/L and MST = 40 mN/m (producer Yarrowia lipolytica), CMC = 83 mg/L and MST = 43 mN/m (producer Candida bombicola). Lower interfacial tension causes that non-polar carbon sourcecan be easily utilized by microorganisms, thus dependence of interfacial tension between organic phase and surfactant solution was measured. Kerosene and crude oil were chosen as representatives of organic phase. Biosurfactant produced by Yarrowia lipolytica was found to be more effective for remediation application, because its solution decreased the interfacial tension by 80%.
