Disclosed is a method for purifying a soil using a microbe to decompose a lubricating oil, in which a soil contaminated by a lubricating oil is purified by a treatment using a microbe strain for decomposing a lubricating oil selected from the group consisting of Sphingobacterium sp. OLu-1 (accession number KCTC 12351BP), Novosphingobium capsulatum OLu-2 (accession number KCTC 12352BP), Acinetobacter sp. OLu-3 (accession number KCTC 12353BP), and Xanthomonas sp. OLu-4 (accession number KCTC 12354BP). The microbe strain according to the present invention effectively purifies a soil contaminated by a lubricating oil in a concentration of approximately 500 to 7500 ppm, especially, a soil contaminated by a lubricating oil in a lower concentration of approximately 500 to 2000 ppm as a purified soil firstly purified by a physical or chemical means, thereby recovering an ecological integrity of the soil to improve a recycling possibility. |
