At present microbialremediation is a main measure for removing high molecular weight PAHs from the soil, but it also has somelimitations. In the process of seeking effective ways to repair PAHs contaminated soil, bioremediation technologyis emerge as the times require. In this paper the theoretical basis and difficulties of bioremediation of PAHscontaminated soil be take as the main line, the microbial degradation mechanism of high molecular weight PAHsin soil prehensive reviewed. bined with the curre
