Production of trehalolipid biosurfactants by Rhodococcus erythropolis S67 depending on the growth temperature was studied. R. erythropolis S67 produced glycolipid biosurfactants such as 2,3,4-succinoyl-octanoyl-decanoyl-2′-decanoyl trehalose and 2,3,4-succinoyl-dioctanoyl-2′-decanoyl trehalose during the… Click to show full abstract
Production of trehalolipid biosurfactants by Rhodococcus erythropolis S67 depending on the growth temperature was studied. R. erythropolis S67 produced glycolipid biosurfactants such as 2,3,4-succinoyl-octanoyl-decanoyl-2′-decanoyl trehalose and 2,3,4-succinoyl-dioctanoyl-2′-decanoyl trehalose during the growth in n-hexadecane medium at 26 and 10 °C, despite the different aggregate state of the hydrophobic substrate at low temperature. The surface tension of culture medium was found being reduced from 72 to 27 and 45 mN m−1, respectively. Production of trehalolipid biosurfactants by R. erythropolis S67 at low temperature could be useful for the biodegradation of petroleum hydrocarbons at low temperatures by enhancing the bioremediation performance in cold regions.Graphical abstract
