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, 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.
研究了红球菌 S67 生产海藻糖脂生物表面活性剂的能力，这取决于生长温度。尽管在低温下疏水性底物的聚集状态不同，但红球菌 S67 在 26 和 10°C 的正十六烷培养基中生长时，产生了糖脂生物表面活性剂，如 2,3,4-琥珀酰辛酰癸酰-2'-癸酰海藻糖和 2,3,4-琥珀酰二辛酰-2'-癸酰海藻糖。培养基的表面张力分别从 72 降低到 27 和 45 mN/m。在低温下，红球菌 S67 生产海藻糖脂生物表面活性剂可用于增强寒冷地区的生物修复性能，从而促进低温下石油烃的生物降解。
