Abstract
This research focuses on bioremediation method of oily contaminated soil. Three sets of bioremediation experiment were conducted using bioprocessing medicines and water with Pseudomonas mendocina. The best experimental condition for bioremediation of oily contaminated soil is well discussed. Oil concentration in the soil was measured using the gravimetric analysis method after extracting with normal hexane. Moreover, a qualitative analysis of the oily contaminated soil was investigated by means of mass spectroscopy method (GC-MS). The experimental results showed that an attack of bacteria on the oily contaminated soil caused a significant decrease of the TPH density less than 20% from its original value 5600ppm.
