Polyaromatic hydrocarbons (PAHs) in the petroleum contaminated soil is toxic for human health and difficult to be degraded by indigenous microorganisms. In this paper, we examined the effect of mixing compost into the contaminated soil for enhancement of PAHs degradation. We used メpre-cultured compostモ containing effective microorganisms for remediation and it was cultivated compost with PAHs reagents for several weeks. Enhancement of PAHs degradation was demonstrated by mixing the pre-cultured compost into the recent contaminated soil. We also revealed that the soil after bioremediation is safety because it did not inhibit the growth of the plant. |
