【 摘 要 】

Recovery tests of crude oil by using bio surfactant of indigenous bacteria Pseudomonas peli, Pseudomonas citronellolis, Burkholderia glumae and Bacillus firmus. The bio surfactants were prepared with the variation concentrations of molasses carbon source; 0, 5, 10, 15, 20, and 25 %. The results showed that 10 g samples, which concentration 18.64% TPH could be dissolved in the bio surfactant 10%. Optimally in the molasses carbon source concentrations for each bacterium at 5, 10, 20 and 15 % with oil recovery as much as 31.92, 17.65, 22.32, and 14.38 % respectively. Oil components which extracted by bio surfactant were analyzed by using GLC (Gas Liquid Chromatography). The bio surfactants of Pseudomonas peli could dissolve oil fraction temperatures; 139.85; 144.69; 149.98; 1.55.03: 174.22 °C, Pseudomonas citronellolis could dissolve oil fraction temperatures; 139.13; 142.64;147.99; 155.03; 159.85; 164.50 °C, Burkholderia glumae could dissolve oil fraction temperatures 144.69; 149.98; 155.03; 159.85; 164.50 °C, and Bacillus firmus could dissolve oil fraction temperatures; 149.98; 155.03; 158.46; 164.50 °C.
